问题 How can i use SOCKS4 and SOCKS5 proxies with aiohttp ClientSession? Need some small example. Thanks! 回答1: Have you tried aiosocks ? import asyncio import aiosocks from aiosocks.connector import SocksConnector conn = SocksConnector(proxy=aiosocks.Socks5Addr(PROXY_ADDRESS, PROXY_PORT), proxy_auth=None, remote_resolve=True) session = aiohttp.ClientSession(connector=conn) async with session.get('http://python.org') as resp: assert resp.status == 200 来源： https://stackoverflow.com/questions

问题 I've written a script in python using asyncio association with aiohttp library to parse the names out of pop up boxes initiated upon clicking on contact info buttons out of diffetent agency information located within a table from this website asynchronously. The webpage displayes the tabular contents across 513 pages. I encountered this error too many file descriptors in select() when I tried with asyncio.get_event_loop() but when I came across this thread I could see that there is a

问题 I've written a script in asyncio in association with aiohttp library to parse the content of a website asynchronously. I've tried to apply the logic within the following script the way it is usually applied in scrapy . However, when I execute my script, it acts like how syncronous libraries like requests or urllib.request do. Therefore, it is very slow and doesn't serve the purpose. I know I can get around this by defining all the next page link within the link variable. But, am I not doing

问题 By default, asyncio runs coroutines synchronously. If they contain blocking IO code, they still wait for it to return. A way around this is loop.run_in_executor(), which converts the code into threads. If a thread blocks on IO, another thread can start executing. So you don't waste time waiting for IO calls. If you use asyncio without executors, you loose those speedups. So I was wondering, why do you have to use executors explicitly. Why not enable them by default ? (In the following, I'll

问题 I am trying to connect to a .onion site using python.

问题 I am trying to get a basic logger for aiohttp working, but there are simply no log messages being logged. Note_ logging custom messages works as expected. async def main_page(request: web.Request): return "hello world" def setup_routes(app): app.router.add_get('/', main_page) async def init(loop): # load config from yaml file in current dir conf = load_config(str(pathlib.Path('.') / 'async_config.yml')) # setup application and extensions app = web.Application(loop=loop) # setup views and

问题 This example of aiohttp server in a thread fails with an RuntimeError: There is no current event loop in thread 'Thread-1'. error: import threading from aiohttp import web def aiohttp_server(): def say_hello(request): return web.Response(text='Hello, world') app = web.Application(debug=True) app.add_routes([web.get('/', say_hello)]) web.run_app(app) t = threading.Thread(target=aiohttp_server) t.start() How to run a aiohttp server in thread? 回答1: Create handler in main thread and manually

问题 My aiohttp webserver uses a global variable that changes over time: from aiohttp import web shared_item = 'bla' async def handle(request): if items['test'] == 'val': shared_item = 'doeda' print(shared_item) app = web.Application() app.router.add_get('/', handle) web.run_app(app, host='somewhere.com', port=8181) Results in: UnboundLocalError: local variable 'shared_item' referenced before assignment How would I properly use a shared variable shared_item ? 回答1: Push your shared variable into

问题 There is relatively new Python 3 aiohttp library that contains client/server. Does it contain ORM? If not - is it possible to use it with 3-rd party ORM? If not possible - for which purpose it could be used? I don't mean that app could not be written without ORM, but major waste of Python Frameworks support it and developers are used to such style of programming. 回答1: Short answer -- aiohttp has no ORM yet. You can use SQLAlchemy-like queries for aiopg driver, see example The same is

问题 I'm trying to integrate an aiohttp web server into a Crossbar+Autobahn system architecture. More in detail, when the aiohttp server receive a certain API call, it has to publish a message to a Crossbar router. I've seen this example on the official repos but i've no clue on how to integrate it on my application. Ideally, i would like to be able to do this # class SampleTaskController(object): async def handle_get_request(self, request: web.Request) -> web.Response: self.publisher.publish('com
