响应

在sanic.response模块中使用函数创建响应。

Plain Text

from sanic import response
@app.route('/text')
def handle_request(request):
    return response.text('Hello world!')

HTML

from sanic import response
@app.route('/html')
def handle_request(request):
    return response.html('<p>Hello world!</p>')

JSON

from sanic import response
@app.route('/json')
def handle_request(request):
    return response.json({'message': 'Hello world!'})

File

from sanic import response
@app.route('/file')
async def handle_request(request):
    return await response.file('/srv/www/whatever.png')

Streaming

from sanic import response
@app.route("/streaming")
async def index(request):
    async def streaming_fn(response):
        response.write('foo')
        response.write('bar')
    return response.stream(streaming_fn, content_type='text/plain')

Redirect

from sanic import response
@app.route('/redirect')
def handle_request(request):
    return response.redirect('/json')

Raw

Response without encoding the body

from sanic import response
@app.route('/raw')
def handle_request(request):
    return response.raw('raw data')

Modify headers or status

To modify headers or status code, pass the headers or status argument to those functions:

from sanic import response
@app.route('/json')
def handle_request(request):
    return response.json(
        {'message': 'Hello world!'},
        headers={'X-Served-By': 'sanic'},
        status=200
    )
