# 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.

## Examples
|
|
|
|
```python
|
|
from sanic import Sanic
|
|
from sanic.response import text
|
|
|
|
@app.route('/tag/<tag>')
|
|
async def person_handler(request, tag):
|
|
return text('Tag - {}'.format(tag))
|
|
|
|
@app.route('/number/<integer_arg:int>')
|
|
async def person_handler(request, integer_arg):
|
|
return text('Integer - {}'.format(integer_arg))
|
|
|
|
@app.route('/number/<number_arg:number>')
|
|
async def person_handler(request, number_arg):
|
|
return text('Number - {}'.format(number))
|
|
|
|
@app.route('/person/<name:[A-z]>')
|
|
async def person_handler(request, name):
|
|
return text('Person - {}'.format(name))
|
|
|
|
@app.route('/folder/<folder_id:[A-z0-9]{0,4}>')
|
|
async def folder_handler(request, folder_id):
|
|
return text('Folder - {}'.format(folder_id))
|
|
|

```
