install sanic：python3 -m pip install sanic

example

from sanic import sanic

from sanic.response import text
async def test(request):
return text('hello world!')

from sanic.response import json

async def test(request):
return json()

要指定乙個引數，可以用像這樣的角引號包圍它。請求引數將作為關鍵字引數傳遞給路線處理程式函式。

demo

from sanic.response import text

async def tag_handler(request, tag):
return text('tag - {}'.format(tag))

demo：

from sanic.response import text

async def integer_handler(request, integer_arg):
return text('integer - {}'.format(integer_arg))
async def number_handler(request, number_arg):
return text('number - {}'.format(number_arg))
async def person_handler(request, name):
return text('person - {}'.format(name))
async def folder_handler(request, folder_id):
return text('folder - {}'.format(folder_id))

路由裝飾器接受乙個可選的引數，方法，它允許處理程式函式與列表中的任何http方法一起工作。

demo_1
from sanic.response import text
async def post_handler(request):
return text('post request - {}'.format(request.json))
async def get_handler(request):
return text('get request - {}'.format(request.args))
demo_2
from sanic.response import text
async def post_handler(request):
return text('post request - {}'.format(request.json))
async def get_handler(request):
return text('get request - {}'.format(request.args))

from sanic.response import text

# define the handler functions
async def handler1(request):
return text('ok')
async def handler2(request, name):
return text('folder - {}'.format(name))
async def person_handler2(request, name):
return text('person - {}'.format(name))
# add each handler function as a route

return text('post - {}'.format(post_id))

notice:

# /posts/5?arg_one=one&arg_two=two

# /posts/5?arg_one=one&arg_one=two

websocket 可以通過裝飾路由實現

demo：

async def feed(request, ws):

while true:

data = 'hello!'

print('sending: ' + data)

await ws.send(data)

data = await ws.recv()

print('received: ' + data)

另外，新增 websocket 路由方法可以代替裝飾器

async def feed(request, ws):

pass

from sanic import response

def handle_request(request):
return response.text('hello world!')

from sanic import response

def handle_request(request):
return response.html('hello world!
')

from sanic import response

def handle_request(request):
return response.json()

from sanic import response

async def handle_request(request):
return await response.file('/srv/www/whatever.png')

from sanic import response

async def index(request):
async def streaming_fn(response):
response.write('foo')
response.write('bar')
return response.stream(streaming_fn, content_type='text/plain')

from sanic import response

async def handle_request(request):
return await response.file_stream('/srv/www/whatever.png')

from sanic import response

def handle_request(request):
return response.redirect('/json')

from sanic import response

def handle_request(request):
return response.raw(『 raw data 』)

from sanic import response

def handle_request(request):
return response.json(
,headers=,
status=200
)
