Continuation

Hi,

It would be amazing if you were continue this project

Workarounds I believe are possible to find.

Request connection failed. Exiting...

- Using Windows 10

Issue

I had an issue when trying to run the code. After I entered the URL into the console, an error message appeared:
"Request connection failed. Exiting..."

Output

C:\Users\User\AppData\Roaming\Python\Python39\site-packages\grequests.py:22: MonkeyPatchWarning: Monkey-patching ssl after ssl has already been imported may lead to errors, including RecursionError on Python 3.6. It may also silently lead to incorrect behaviour on Python 3.7. Please monkey-patch earlier. See https://github.com/gevent/gevent/issues/1016. Modules that had direct imports (NOT patched): ['urllib3.util.ssl_ (C:\\Users\\User\\AppData\\Roaming\\Python\\Python39\\site-packages\\urllib3\\util\\ssl_.py)', 'urllib3.util (C:\\Users\\User\\AppData\\Roaming\\Python\\Python39\\site-packages\\urllib3\\util\\__init__.py)'].

[>] Request connection failed. Exiting...

I then removed the try-except statement from the code @ Line 88 and ran it again. This was the error I received:
"RecursionError: maximum recursion depth exceeded"

Output:

How-To Fix

I then went on StackOverflow here (first solution) and found out that I needed to add these two lines of code at the top of the code:

import gevent.monkey
gevent.monkey.patch_all()

After inserting those two lines at the top of the code, everything seems to work fine.

Conclusion

I don't know why the code isn't working before the fix. I thought I would just let you know here and perhaps help others
who might have the same issue. I have to say, I love this program. It's working great and I appreciate your time and effort.

Support

Thanks for the tool. ❤❤

Can you add support to download files from the https://www.coursehero.com/tutors-problems/* endpoint. eg. the tool can download https://www.coursehero.com/file/61519475/Human-Services-Assignment-1-docx/ but not https://www.coursehero.com/tutors-problems/Social-Psychology/38685580-What-is-a-civic-professional-in-relation-to-the-Human-Service/

Is this still working? Cause I've never face this kind of problem before

Help me please.

Possible way to make a continuation

I realized that when you search for text in the coursehero document on google, it has the problem and answer in the page description. That means coursehero has a text version of the pdf openly available for web crawlers.

I don't know how you would get the full thing though. Theres a json in the html with some but not all problems/answers. Maybe make a request to the page disguised as a google web crawler.
