Sanic is a Flask-like Python 3.5+ web server that's written to go fast. It's based on the work done by the amazing folks at magicstack, and was inspired by this article: https://magic.io/blog/uvloop-blazing-fast-python-networking/.
|
||||
|
||||
On top of being Flask-like, Sanic supports async request handlers. This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.
|
||||
|
||||
## Benchmarks
|
||||
|
||||
All tests were run on an AWS medium instance running ubuntu, using 1 process. Each script delivered a small JSON response and was tested with wrk using 100 connections. Pypy was tested for Falcon and Flask but did not speed up requests.

It is also useful for API versioning, where one blueprint may point at

## Use-case: API versioning
|
||||
|
||||
Blueprints can be very useful for API versioning, where one blueprint may point
|
||||
at `/v1/<routes>`, and another pointing at `/v2/<routes>`.
|
||||
|
||||
When a blueprint is initialised, it can take an optional `url_prefix` argument,
|
||||
which will be prepended to all routes defined on the blueprint. This feature
|
||||
can be used to implement our API versioning scheme.
|
||||
|
||||
```python
|
||||
# blueprints.py
|
||||
from sanic.response import text
|
||||
from sanic import Blueprint
|
||||
|
||||
blueprint_v1 = Blueprint('v1')
|
||||
blueprint_v2 = Blueprint('v2')
|
||||
|
||||
@blueprint_v1.route('/')
|
||||
async def api_v1_root(request):
|
||||
return text('Welcome to version 1 of our documentation')
|
||||
|
||||
@blueprint_v2.route('/')
|
||||
async def api_v2_root(request):
|
||||
return text('Welcome to version 2 of our documentation')
|
||||
```
|
||||
|
||||
When we register our blueprints on the app, the routes `/v1` and `/v2` will now
|
||||
point to the individual blueprints, which allows the creation of *sub-sites*
|
||||
for each API version.
|
||||
|
||||
```python
|
||||
# main.py
|
||||
from sanic import Sanic
|
||||
from blueprints import blueprint_v1, blueprint_v2

# Class-Based Views
|
||||
|
||||
Sanic has simple class based implementation. You should implement methods(get, post, put, patch, delete) for the class to every HTTP method you want to support. If someone tries to use a method that has not been implemented, there will be 405 response.
|
||||
Class-based views are simply classes which implement response behaviour to
|
||||
requests. They provide a way to compartmentalise handling of different HTTP
|
||||
request types at the same endpoint. Rather than defining and decorating three
|
||||
different handler functions, one for each of an endpoint's supported request
|
||||
type, the endpoint can be assigned a class-based view.
|
||||
|
||||
## Defining views
|
||||
|
||||
A class-based view should subclass `HTTPMethodView`. You can then implement
|
||||
class methods for every HTTP request type you want to support. If a request is
|
||||
received that has no defined method, a `405: Method not allowed` response will
|
||||
be generated.
|
||||
|
||||
To register a class-based view on an endpoint, the `app.add_route` method is
|
||||
used. The first argument should be the defined class with the method `as_view`
|
||||
invoked, and the second should be the URL endpoint.
|
||||
|
||||
The available methods are `get`, `post`, `put`, `patch`, and `delete`. A class
|
||||
using all these methods would look like the following.
|
||||
|
||||
## Examples
|
||||

|
||||
from sanic import Sanic

# Contributing
|
||||
|
||||
Thank you for your interest!
|
||||
Thank you for your interest! Sanic is always looking for contributors. If you
|
||||
don't feel comfortable contributing code, adding docstrings to the source files
|
||||
is very appreciated.
|
||||
|
||||
## Running tests
|
||||
|
||||
* `python -m pip install pytest`
|
||||
* `python -m pytest tests`
|
||||
|
||||
## Documentation
|
||||
|
||||
Sanic's documentation is built
|
||||
using [sphinx](http://www.sphinx-doc.org/en/1.5.1/). Guides are written in
|
||||
Markdown and can be found in the `docs` folder, while the module reference is
|
||||
automatically generated using `sphinx-apidoc`.
|
||||
|
||||
To generate the documentation from scratch:
|
||||
|
||||
```bash
|
||||
sphinx-apidoc -fo docs/_api/ sanic
|
||||
sphinx-build -b html docs docs/_build
|
||||
```
|
||||
|
||||
The HTML documentation will be created in the `docs/_build` folder.
|
||||
|
||||
## Warning
|
||||
One of the main goals of Sanic is speed. Code that lowers the performance of Sanic without significant gains in usability, security, or features may not be merged.

# Cookies
|
||||
|

## Request
|
||||
Cookies are pieces of data which persist inside a user's browser. Sanic can
|
||||
both read and write cookies, which are stored as key-value pairs.
|
||||
|
||||
Request cookies can be accessed via the request.cookie dictionary
|
||||
## Reading cookies

|
||||
### Example
|
||||
A user's cookies can be accessed `Request` object's `cookie` dictionary.
|
||||
|
||||
```python
|
||||
from sanic import Sanic
|
||||

## Writing cookies
|
||||
|
||||
Response cookies can be set like dictionary values and
|
||||
have the following parameters available:
|
||||
|
||||
* expires - datetime - Time for cookie to expire on the client's browser
|
||||
* path - string - The Path attribute specifies the subset of URLs to
|
||||
which this cookie applies
|
||||
* comment - string - Cookie comment (metadata)
|
||||
* domain - string - Specifies the domain for which the
|
||||
cookie is valid. An explicitly specified domain must always
|
||||
start with a dot.
|
||||
* max-age - number - Number of seconds the cookie should live for
|
||||
* secure - boolean - Specifies whether the cookie will only be sent via
|
||||
HTTPS
|
||||
* httponly - boolean - Specifies whether the cookie cannot be read
|
||||
by javascript
|
||||
|
||||
### Example
|
||||
When returning a response, cookies can be set on the `Response` object.
|
||||
|

# Custom Protocols
|
||||
|
||||
You can change the behavior of protocol by using custom protocol.
|
||||
If you want to use custom protocol, you should put subclass of [protocol class](https://docs.python.org/3/library/asyncio-protocol.html#protocol-classes) in the protocol keyword argument of `sanic.run()`. The constructor of custom protocol class gets following keyword arguments from Sanic.
|
||||
*Note: this is advanced usage, and most readers will not need such functionality.*
|
||||
|
||||
* loop
|
||||
`loop` is an asyncio compatible event loop.
|
||||
You can change the behavior of Sanic's protocol by specifying a custom
|
||||
protocol, which should be a subclass
|
||||
of
|
||||
[asyncio.protocol](https://docs.python.org/3/library/asyncio-protocol.html#protocol-classes).
|
||||
This protocol can then be passed as the keyword argument `protocol` to the `sanic.run` method.
|
||||
|
||||
* connections
|
||||
`connections` is a `set object` to store protocol objects.
|
||||
When Sanic receives `SIGINT` or `SIGTERM`, Sanic executes `protocol.close_if_idle()` for a `protocol objects` stored in connections.
|
||||
The constructor of the custom protocol class receives the following keyword
|
||||
arguments from Sanic.
|
||||
|
||||
* signal
|
||||
`signal` is a `sanic.server.Signal object` with `stopped attribute`.
|
||||
When Sanic receives `SIGINT` or `SIGTERM`, `signal.stopped` becomes `True`.
|
||||
|
||||
* request_handler
|
||||
`request_handler` is a coroutine that takes a `sanic.request.Request` object and a `response callback` as arguments.
|
||||
|
||||
* error_handler
|
||||
`error_handler` is a `sanic.exceptions.Handler` object.
|
||||
|
||||
* request_timeout
|
||||
`request_timeout` is seconds for timeout.
|
||||
|
||||
* request_max_size
|
||||
`request_max_size` is bytes of max request size.
|
||||
- `loop`: an `asyncio`-compatible event loop.
|
||||
- `connections`: a `set` to store protocol objects. When Sanic receives
|
||||
`SIGINT` or `SIGTERM`, it executes `protocol.close_if_idle` for all protocol
|
||||
objects stored in this set.
|
||||
- `signal`: a `sanic.server.Signal` object with the `stopped` attribute. When
|
||||
Sanic receives `SIGINT` or `SIGTERM`, `signal.stopped` is assigned `True`.
|
||||
- `request_handler`: a coroutine that takes a `sanic.request.Request` object
|
||||
and a `response` callback as arguments.
|
||||
- `error_handler`: a `sanic.exceptions.Handler` which is called when exceptions
|
||||
are raised.
|
||||
- `request_timeout`: the number of seconds before a request times out.
|
||||
- `request_max_size`: an integer specifying the maximum size of a request, in bytes.
|
||||
|
||||
## Example
|
||||
By default protocol, an error occurs, if the handler does not return an `HTTPResponse object`.
|
||||
In this example, By rewriting `write_response()`, if the handler returns `str`, it will be converted to an `HTTPResponse object`.
|
||||
|
||||
An error occurs in the default protocol if a handler function does not return
|
||||
an `HTTPResponse` object.
|
||||
|
||||
By overriding the `write_response` protocol method, if a handler returns a
|
||||
string it will be converted to an `HTTPResponse object`.

# Deploying
|
||||
|
||||
When it comes to deploying Sanic, there's not much to it, but there are
|
||||
a few things to take note of.
|
||||
Deploying Sanic is made simple by the inbuilt webserver. After defining an
|
||||
instance of `sanic.Sanic`, we can call the `run` method with the following
|
||||
keyword arguments:
|
||||
|
||||
- `host` *(default `"127.0.0.1"`)*: Address to host the server on.
|
||||
- `port` *(default `8000`)*: Port to host the server on.
|
||||
- `debug` *(default `False`)*: Enables debug output (slows server).
|
||||
- `before_start` *(default `None`)*: Function or list of functions to be executed
|
||||
before the server starts accepting connections.
|
||||
- `after_start` *(default `None`)*: Function or list of functions to be executed
|
||||
after the server starts accepting connections.
|
||||
- `before_stop` *(default `None`)*: Function or list of functions to be
|
||||
executed when a stop signal is received before it is
|
||||
respected.
|
||||
- `after_stop` *(default `None`)*: Function or list of functions to be executed
|
||||
when all requests are complete.
|
||||
- `ssl` *(default `None`)*: `SSLContext` for SSL encryption of worker(s).
|
||||
- `sock` *(default `None`)*: Socket for the server to accept connections from.
|
||||
- `workers` *(default `1`)*: Number of worker processes to spawn.
|
||||
- `loop` *(default `None`)*: An `asyncio`-compatible event loop. If none is
|
||||
specified, Sanic creates its own event loop.
|
||||
- `protocol` *(default `HttpProtocol`)*: Subclass
|
||||
of
|
||||
[asyncio.protocol](https://docs.python.org/3/library/asyncio-protocol.html#protocol-classes).
|
||||
|
||||
## Workers
|
||||
|
||||
By default, Sanic listens in the main process using only 1 CPU core.
|
||||
To crank up the juice, just specify the number of workers in the run
|
||||
arguments like so:

|
||||
app.run(host='0.0.0.0', port=1337, workers=4)
|
||||
```
|
||||
|

Sanic will automatically spin up multiple processes and route
|
||||
traffic between them. We recommend as many workers as you have
|
||||
available cores.

|
||||
|
||||

|
||||
|
||||
`python -m sanic server.app --host=0.0.0.0 --port=1337 --workers=4`
|
||||
|
||||
With this way of running sanic, it is not necessary to run app.run in
|
||||
your python file. If you do, just make sure you wrap it in name == main
|
||||
like so:
|
||||
With this way of running sanic, it is not necessary to invoke `app.run` in your
|
||||
Python file. If you do, make sure you wrap it so that it only executes when
|
||||
directly run by the interpreter.
|
||||
|
||||
```python
|
||||
if __name__ == '__main__':
|
||||
app.run(host='0.0.0.0', port=1337, workers=4)

# Exceptions
|
||||
|

Exceptions can be thrown from within request handlers and will automatically be handled by Sanic. Exceptions take a message as their first argument, and can also take a status_code to be passed back in the HTTP response. Check sanic.exceptions for the full list of exceptions to throw.

also take a status code to be passed back in the HTTP response.
|
||||
|
||||
## Throwing an exception
|
||||
|
||||
To throw an exception, simply `raise` the relevant exception from the
|
||||
`sanic.exceptions` module.
|
||||
|
||||
```python
|
||||
from sanic import Sanic
|
||||
from sanic.exceptions import ServerError
|
||||
|
||||
@app.route('/killme')
|
||||
def i_am_ready_to_die(request):
|
||||
raise ServerError("Something bad happened")
|
||||
raise ServerError("Something bad happened", status_code=500)
|
||||
```

||||

## Handling Exceptions
|
||||
## Handling exceptions
|
||||
|
||||
Just use the @exception decorator. The decorator expects a list of exceptions to handle as arguments. You can pass SanicException to catch them all! The exception handler must expect a request and exception object as arguments.
|
||||
To override Sanic's default handling of an exception, the `@app.exception`
|
||||
decorator is used. The decorator expects a list of exceptions to handle as
|
||||
arguments. You can pass `SanicException` to catch them all! The decorated
|
||||
exception handler function must take a `Request` and `Exception` object as
|
||||
arguments.
|
||||
|
||||
```python
|
||||
from sanic import Sanic
|
||||
from sanic.response import text
|
||||
from sanic.exceptions import NotFound
|
||||
|
||||
@app.exception(NotFound)
|
||||
def ignore_404s(request, exception):
|
||||
return text("Yep, I totally found the page: {}".format(request.url))
|
||||
```
|
||||
```
|
||||
|
||||
## Useful exceptions
|
||||
|
||||
Some of the most useful exceptions are presented below:
|
||||
|
||||
- `NotFound`: called when a suitable route for the request isn't found.

# Getting Started
|
||||
|
||||
Make sure you have pip and python 3.5 before starting
|
||||
Make sure you have both [pip](https://pip.pypa.io/en/stable/installing/) and at
|
||||
least version 3.5 of Python before starting. Sanic uses the new `async`/`await`
|
||||
syntax, so earlier versions of python won't work.
|
||||
|
||||
## Benchmarks
|
||||
* Install Sanic
|
||||
* `python3 -m pip install sanic`
|
||||
* Edit main.py to include:
|
||||
```python
|
||||
from sanic import Sanic
|
||||
from sanic.response import json
|
||||
1. Install Sanic: `python3 -m pip install sanic`
|
||||
2. Create a file called `main.py` with the following code:
|
||||
|
||||
app = Sanic(__name__)
|
||||
```python
|
||||
from sanic import Sanic
|
||||
from sanic.response import text
|
||||
|
||||
@app.route("/")
|
||||
async def test(request):
|
||||
return json({ "hello": "world" })
|
||||
app = Sanic(__name__)
|
||||
|
||||
app.run(host="0.0.0.0", port=8000, debug=True)
|
||||
```
|
||||
* Run `python3 main.py`
|
||||
@app.route("/")
|
||||
async def test(request):
|
||||
return text('Hello world!')
|
||||
|
||||
You now have a working Sanic server! To continue on, check out:
|
||||
* [Request Data](request_data.md)
|
||||
* [Routing](routing.md)
|
||||
app.run(host="0.0.0.0", port=8000, debug=True)
|
||||
```
|
||||
|
||||
3. Run the server: `python3 main.py`
|
||||
4. Open the address `http://0.0.0.0:8000` in your web browser. You should see
|
||||
the message *Hello world!*.
|
||||
|
||||
You now have a working Sanic server!

# Middleware
|
||||
|
||||
Middleware can be executed before or after requests. It is executed in the order it was registered. If middleware returns a response object, the request will stop processing and a response will be returned.
|
||||
Middleware are functions which are executed before or after requests to the
|
||||
server. They can be used to modify the *request to* or *response from*
|
||||
user-defined handler functions.
|
||||
|
||||
Middleware is registered via the middleware decorator, and can either be added as 'request' or 'response' middleware, based on the argument provided in the decorator. Response middleware receives both the request and the response as arguments.
|
||||
There are two types of middleware: request and response. Both are declared
|
||||
using the `@app.middleware` decorator, with the decorator's parameter being a
|
||||
string representing its type: `'request'` or `'response'`. Response middleware
|
||||
receives both the request and the response as arguments.
|
||||
|
||||
## Examples
|
||||
|
||||
The simplest middleware doesn't modify the request or response at all:
|
||||
|
||||
```python
|
||||
app = Sanic(__name__)
|
||||
|
||||
@app.middleware
|
||||
async def halt_request(request):
|
||||
print("I am a spy")
|
||||
|
||||
@app.middleware('request')
|
||||
async def halt_request(request):
|
||||
return text('I halted the request')
|
||||
async def print_on_request(request):
|
||||
print("I print when a request is received by the server")
|
||||
|
||||
@app.middleware('response')
|
||||
async def halt_response(request, response):
|
||||
return text('I halted the response')
|
||||
|
||||
@app.route('/')
|
||||
async def handler(request):
|
||||
return text('I would like to speak now please')
|
||||
|
||||
app.run(host="0.0.0.0", port=8000)
|
||||
async def print_on_response(request, response):
|
||||
print("I print when a response is returned by the server")
|
||||
```
|
||||
|
||||
## Middleware chain
|
||||
## Modifying the request or response
|
||||
|
||||
If you want to apply the middleware as a chain, applying more than one, is so easy. You only have to be aware that you do **not return** any response in your middleware:
|
||||
Middleware can modify the request or response parameter it is given, *as long
|
||||
as it does not return it*. The following example shows a practical use-case for
|
||||
this.
|
||||
|
||||
```python
|
||||
app = Sanic(__name__)
|
||||
|

|
|||
app.run(host="0.0.0.0", port=8000)
|
||||
```
|
||||
|
||||
The above code will apply the two middlewares in order. First the middleware **custom_banner** will change the HTTP Response headers *Server* by *Fake-Server*, and the second middleware **prevent_xss** will add the HTTP Headers for prevent Cross-Site-Scripting (XSS) attacks.
|
||||
The above code will apply the two middleware in order. First, the middleware
|
||||
**custom_banner** will change the HTTP response header *Server* to
|
||||
*Fake-Server*, and the second middleware **prevent_xss** will add the HTTP
|
||||
header for preventing Cross-Site-Scripting (XSS) attacks. These two functions
|
||||
are invoked *after* a user function returns a response.
|
||||
|
||||
## Responding early
|
||||
|
||||
If middleware returns a `HTTPResponse` object, the request will stop processing
|
||||
and the response will be returned. If this occurs to a request before the
|
||||
relevant user route handler is reached, the handler will never be called.
|
||||
Returning a response will also prevent any further middleware from running.
|
||||
|
||||
```python
|
||||
@app.middleware('request')
|
||||
async def halt_request(request):
|
||||
return text('I halted the request')

||||

# Request Data
|
||||
|
||||
## Properties
|
||||
When an endpoint receives a HTTP request, the route function is passed a
|
||||
`Request` object.
|
||||
|
||||
The following request variables are accessible as properties:
|
||||
The following variables are accessible as properties on `Request` objects:
|
||||
|
||||
`request.files` (dictionary of File objects) - List of files that have a name, body, and type
|
||||
`request.json` (any) - JSON body
|
||||
`request.args` (dict) - Query String variables. Use getlist to get multiple of the same name
|
||||
`request.form` (dict) - Posted form variables. Use getlist to get multiple of the same name
|
||||
`request.body` (bytes) - Posted raw body. To get the raw data, regardless of content type
|
||||
- `json` (any) - JSON body
|
||||
|
||||
See request.py for more information
|
||||
```python
|
||||
from sanic.response import json
|
||||
|
||||
@app.route("/json")
|
||||
def post_json(request):
|
||||
return json({ "received": True, "message": request.json })
|
||||
```
|
||||
|
||||
- `args` (dict) - Query string variables. A query string is the section of a
|
||||
URL that resembles `?key1=value1&key2=value2`. If that URL were to be parsed,
|
||||
the `args` dictionary would look like `{'key1': 'value1', 'key2': 'value2'}`.
|
||||
The request's `query_string` variable holds the unparsed string value.
|
||||
|
||||
## Examples
|
||||
```python
|
||||
from sanic.response import json
|
||||
|
||||
@app.route("/query_string")
|
||||
def query_string(request):
|
||||
return json({ "parsed": True, "args": request.args, "url": request.url, "query_string": request.query_string })
|
||||
```
|
||||
|
||||
- `files` (dictionary of `File` objects) - List of files that have a name, body, and type
|
||||
|
||||
```python
|
||||
from sanic.response import json
|
||||
|
||||
@app.route("/files")
|
||||
def post_json(request):
|
||||
test_file = request.files.get('test')
|
||||
|
||||
file_parameters = {
|
||||
'body': test_file.body,
|
||||
'name': test_file.name,
|
||||
'type': test_file.type,
|
||||
}
|
||||
|
||||
return json({ "received": True, "file_names": request.files.keys(), "test_file_parameters": file_parameters })
|
||||
```
|
||||
|
||||
- `form` (dict) - Posted form variables.
|
||||
|
||||
```python
|
||||
from sanic.response import json
|
||||
|
||||
@app.route("/form")
|
||||
def post_json(request):
|
||||
return json({ "received": True, "form_data": request.form, "test": request.form.get('test') })
|
||||
```
|
||||
|
||||
- `body` (bytes) - Posted raw body. This property allows retrieval of the
|
||||
request's raw data, regardless of content type.
|
||||
|
||||
```python
|
||||
from sanic.response import text
|
||||
|
||||
@app.route("/users", methods=["POST",])
|
||||
def create_user(request):
|
||||
return text("You are trying to create a user with the following POST: %s" % request.body)
|
||||
```
|
||||
|
||||
- `ip` (str) - IP address of the requester.
|
||||
|
||||
## Accessing values using `get` and `getlist`
|
||||
|
||||
The request properties which return a dictionary actually return a subclass of
|
||||
`dict` called `RequestParameters`. The key difference when using this object is
|
||||
the distinction between the `get` and `getlist` methods.
|
||||
|
||||
- `get(key, default=None)` operates as normal, except that when the value of
|
||||
the given key is a list, *only the first item is returned*.
|
||||
- `getlist(key, default=None)` operates as normal, *returning the entire list*.
|
||||
|
||||
```python
|
||||
from sanic import Sanic

# Routing
|
||||
|
||||
Sanic comes with a basic router that supports request parameters. To specify a parameter, surround it with carrots like so: `<PARAM>`. Request parameters will be passed to the request handler functions as keyword arguments. To specify a type, add a :type after the parameter name, in the carrots. If the parameter does not match the type supplied, Sanic will throw a NotFound exception, resulting in a 404 page not found error.
|
||||
Routing allows the user to specify handler functions for different URL endpoints.
|
||||
|
||||
|
||||
## Examples
|
||||
A basic route looks like the following, where `app` is an instance of the
|
||||
`Sanic` class:
|
||||
|
||||
```python
|
||||
from sanic.response import json
|
||||
|
||||
@app.route("/")
|
||||
async def test(request):
|
||||
return json({ "hello": "world" })
|
||||
```
|
||||
|
||||
When the url `http://server.url/` is accessed (the base url of the server), the
|
||||
final `/` is matched by the router to the handler function, `test`, which then
|
||||
returns a JSON object.
|
||||
|
||||
Sanic handler functions must be defined using the `async def` syntax, as they
|
||||
are asynchronous functions.
|
||||
|
||||
## Request parameters
|
||||
|
||||
Sanic comes with a basic router that supports request parameters.
|
||||
|
||||
To specify a parameter, surround it with angle quotes like so: `<PARAM>`.
|
||||
Request parameters will be passed to the route handler functions as keyword
|
||||
arguments.
|
||||
|
||||
```python
|
||||
from sanic import Sanic
|
||||
from sanic.response import text
|
||||
|
||||
@app.route('/tag/<tag>')
|
||||
async def tag_handler(request, tag):
|
||||
return text('Tag - {}'.format(tag))
|
||||
```
|
||||
|
||||
To specify a type for the parameter, add a `:type` after the parameter name,
|
||||
inside the quotes. If the parameter does not match the specified type, Sanic
|
||||
will throw a `NotFound` exception, resulting in a `404: Page not found` error
|
||||
on the URL.
|
||||
|
||||
```python
|
||||
from sanic.response import text
|
||||
|
||||
@app.route('/number/<integer_arg:int>')
|
||||

async def folder_handler(request, folder_id):

||||
return text('Folder - {}'.format(folder_id))
|
||||
|
||||
```
|
||||
|
||||
## HTTP request types
|
||||
|
||||
By default, a route defined on a URL will be used for all requests to that URL.
|
||||
However, the `@app.route` decorator accepts an optional parameter, `methods`,
|
||||
which restricts the handler function to the HTTP methods in the given list.
|
||||
|
||||
```python
|
||||
from sanic.response import text
|
||||
|
||||
@app.route('/post')
|
||||
async def post_handler(request, methods=['POST']):
|
||||

||||

||||
@app.route('/get')
|
||||
async def GET_handler(request, methods=['GET']):
|
||||
return text('GET request - {}'.format(request.args))
|
||||
|
||||
```
|
||||
|
||||
## The `add_route` method
|
||||
|
||||
As we have seen, routes are often specified using the `@app.route` decorator.
|
||||
However, this decorator is really just a wrapper for the `app.add_route`
|
||||
method, which is used as follows:
|
||||
|
||||
```python
|
||||
from sanic.response import text
|
||||
|
||||
# Define the handler functions
|
||||
async def handler1(request):
|
||||
return text('OK')
|
||||

||||
# Add each handler function as a route
|
||||

Static files and directories, such as an image file, are served by Sanic when
