Python requests library pre_request hook

Question

I'm having an issue with trying to switch from an ancient version of python-requests (0.14) to a newer version (1.1, 1.2 whatever). The problem is that we have a system which posts images on twitter using the following library: https://github.com/maraujop/requests-oauth The main problem is with this line of code: ``` # This is taken from the documentation of the library mentioned above session = requests.session(hooks={'pre_request': oauth_hook}) session.post(...) ``` As the Session constructor no longer accepts the hooks parameter. I found that the post method accept the hooks argument though and chagned the code like this: ``` session = requests.session() session.post(..., hooks={'pre_request': oauth_hook}) ``` This is better than before, however the pre_request is no longer accepted in newer version of python-requests (you can find this hook in the documentation of requests 0.14 but not in any of the newer versions). Can somebody help on this?

Accepted Answer

You need to create the request object yourself, pass that to the hook, then call `.prepare()` on it:

```
import requests

request = requests.Request('POST', url, ...)
request = oauth_hook(request)
prepared = request.prepare()
```

then send:

```
session = requests.session()
resp = session.send(prepared)
```
