A simple router for HTTP applications
Project description
http-router – A simple router for HTTP applications
Requirements
python >= 3.7
Installation
http-router should be installed using pip:
pip install http-router
Usage
Create a router:
from http_router import Router
# Initialize the router
router = Router(trim_last_slash=True)Define routes:
@router.route('/simple')
def simple():
return 'result from the fn'Call the router with HTTP path and optionally method to get a match result.
match = router('/simple', method='GET')
assert match, 'HTTP path is ok'
assert match.target is simpleThe router supports regex objects too:
import re
@router.route(re.compile(r'/regexp/\w{3}-\d{2}/?'))
def regex():
return 'result from the fn'But the lib has a simplier interface for the dynamic routes:
@router.route('/users/<username>')
def users():
return 'result from the fn'By default this will capture characters up to the end of the path or the next /.
Optionally, you can use a converter to specify the type of the argument like <variable_name:converter>.
Converter types:
str |
(default) accepts any text without a slash |
int |
accepts positive integers |
float |
accepts positive floating point values |
path |
like string but also accepts slashes |
uuid |
accepts UUID strings |
Convertors are used by prefixing them with a colon, like so:
@router.route('/orders/<order_id:int>')
def orders():
return 'result from the fn'Any unknown convertor will be parsed as a regex:
@router.route('/orders/<order_id:\d{3}>')
def orders():
return 'result from the fn'Multiple paths are supported as well:
@router.route('/', '/home')
def index():
return 'index'Handling HTTP methods:
@router.route('/only-post', methods=['POST'])
def only_post():
return 'only-post'Submounting routes:
subrouter = Router()
@subrouter('/items')
def items():
pass
router = Router()
router.route('/api')(subrouter)
match = router('/api/items', method='GET')
assert match, 'HTTP path is ok'
assert match.target is itemsBug tracker
