I'm running the following, using requests-threads:

Answered 2019-Sep-06 at 17:53The session.request()
method returns a twisted Deferred
object (the requests-threads
code calls twisted.internet.threads.deferToThread()
). You generally don't want to treat this as an asyncio task, not and run under the Twisted reactor.
Instead, you could use twisted.internet.deferred.gatherResults()
to execute the requests concurrently and to gather the responses.
Next, session.run()
calls twisted.internet.task.react()
, which will always exit Python:
[...] this function will also:
[...]
- Exit the application when done, with exit code 0 in case of success and 1 in case of failure.
(bold emphasis mine).
This means that even if your code works, the return results
line is never reached.
If you move out the session.run()
call to be the top-level entry point for your application then things work:
QUESTION
I am trying to perform async HTTP requests by using the requests library in Python. I found that the last version of the library does not directly support async requets. To achive it they provide the requests-threads library that makes use of Twisted to handle asynchronicity. I tried modifying the examples provided to use callbacks instead of await/yield, but the callbacks are not being called.
My sample code is:

The following code works for me:

Install requests-threads
You can use requests-threads like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
