Getting started

To retrieve something from the web:

mport aiohttp

def get_body(url):
    response = yield from request('GET', url)
    return (yield from response.read())

You can use the get command like this anywhere in your asyncio powered program:

response = yield from aiohttp.request('GET', 'http://python.org')
body = yield from response.read()
print (body)

The signature of request is the following:

request(method, url, *,
        params=None,
        data=None,
        headers=None,
        cookies=None,
        files=None,
        auth=None,
        allow_redirects=True,
        max_redirects=10,
        encoding='utf-8',
        version=(1, 1),
        timeout=None,
        conn_timeout=None,
        compress=None,
        chunked=None,
        session=None,
        verify_ssl=True,
        loop=None
)

It constructs and sends a request. It returns response object. Parameters are explained as follow:

  • method: HTTP method
  • url: Request url
  • params: (optional) Dictionary or bytes to be sent in the query string of the new request
  • data: (optional) Dictionary, bytes, or file-like object to send in the body of the request
  • headers: (optional) Dictionary of HTTP Headers to send with the request
  • cookies: (optional) Dict object to send with the request
  • files: (optional) Dictionary of ‘name’: file-like-objects for multipart encoding upload
  • auth: (optional) Auth tuple to enable Basic HTTP Auth
  • timeout: (optional) Float describing the timeout of the request
  • conn_timeout: (optional) Float describing the timeout of the tcp connection
  • allow_redirects: (optional) Boolean. Set to True if POST/PUT/DELETE redirect following is allowed.
  • compress: Boolean. Set to True if request has to be compressed with deflate encoding.
  • chunked: Boolean or Integer. Set to chunk size for chunked transfer encoding.
  • session: aiohttp.Session instance to support connection pooling and session cookies.
  • loop: Optional event loop.
