ReCaptcha bypass #2

Open meta-ks opened 5 years ago

meta-ks commented 5 years ago

This is a very nice wrapper, especially the fuzzy match. Recently irctc and Indian rail started using recaptcha which puts all such apis at halt. Any thougths on how we can get around recaptcha ?

URL in API_ENDPOINT present in utils.py is not working.

Can you elaborate? The API seems fine.

N.B. See the rcheck header, That's the standard ReCaptcha token. If somehow there is a workaround , the rest of @nikhilkumarsingh 's code needs minimal modification.

Actually I tried fetching trains between stations but when I run the code it gives Invalid Request. How can I solve this issue can you please tell.
