aio.http 0.0.3

Build status

Installation

Install with:

pip install aio.http

Configuration

Example configuration for a hello world server

[aio:commands]
run = aio.app.cmd.cmd_run

[server:test]
factory = aio.http.server
protocol = my.example.protocol_factory
port = 8080

And the corresponding protocol_factory

import asyncio
import aiohttp

@asyncio.coroutine
def protocol_factory(name):
    loop = asyncio.get_event_loop()

    webapp = aiohttp.web.Application(loop=loop)
    webapp['name'] = name

    @asyncio.coroutine
    def handle_hello_world(webapp):
        return aiohttp.web.Response(body=b"Hello, world")

    webapp.router.add_route("GET", "/", handle_hello_world)
    return webapp.make_handler()

Running

Run with the aio command

aio run

Configuration

Create a config defining a factory method and a root handler

>>> config = """
... [aio:commands]
... run: aio.app.cmd.cmd_run
...
... [server:test]
... factory: aio.http.server
... port: 7070
... """

Running an http server

By default the http server will respond with a 404 as there are no routes set up

>>> import asyncio
>>> import aiohttp
>>> from aio.app.runner import runner

>>> def run_http_server():
...     yield from runner(['run'], config_string=config)
...
...     @asyncio.coroutine
...     def _test_http_server():
...         result = yield from (
...             yield from aiohttp.request(
...                "GET", "http://localhost:7070")).read()
...         print(result)
...
...     return _test_http_server

>>> from aio.testing import aiofuturetest
>>> aiofuturetest(run_http_server, timeout=1, sleep=1)()
b'404: Not Found'

The server object is accessible from the aio.app.servers[{name}] var

>>> import aio.app
>>> aio.app.servers['test']
<Server sockets=[<socket.socket...laddr=('0.0.0.0', 7070)...]>

Lets clear the app

>>> aio.app.clear()

Running the server with a custom protocol

If you specify a protocol in the server: config, the http server will use that function as a protocol factory.

The function should be a coroutine and is called with the name of the server

>>> def http_protocol_factory(name):
...     loop = asyncio.get_event_loop()
...     webapp = aiohttp.web.Application(loop=loop)
...     webapp['name'] = name
...
...     def handle_hello_world(webapp):
...         return aiohttp.web.Response(body=b"Hello, world")
...
...     webapp.router.add_route("GET", "/", asyncio.coroutine(handle_hello_world))
...     return webapp.make_handler()

>>> aio.http.tests._test_http_protocol = asyncio.coroutine(http_protocol_factory)

>>> config_with_protocol = """
... [aio:commands]
... run: aio.app.cmd.cmd_run
...
... [server:test]
... factory: aio.http.server
... protocol: aio.http.tests._test_http_protocol
... port: 7070
... """

>>> def run_http_server():
...     yield from runner(['run'], config_string=config_with_protocol)
...
...     @asyncio.coroutine
...     def _test_http_server():
...         result = yield from (
...             yield from aiohttp.request(
...                "GET", "http://localhost:7070")).read()
...
...         print(result)
...
...     return _test_http_server

>>> aiofuturetest(run_http_server, timeout=1, sleep=1)()
b'Hello, world'

>>> del aio.http.tests._test_http_protocol
>>> aio.app.clear()
