Authentication failed in Github | python-social-auth

Question

In my django project I use python-social-auth . I am tring to add social login with Github but unfortunately have next error :

Authentication failed: The redirect_uri MUST match the registered callback URL for this application.

Full error looks like this:

Answer 1

尝试在http://127.0.0.1:8000/上注册回调 URL，而不是http://localhost:8000/

Answer 2

The problem was with callback URL of Github. In my case I had language prefix inside URL, didnt expect that Github would be sensitive to that cause other provideres didnt raise error for link without prefix. I fount this post which describe how to show default language without path prefixes. I hope it will help someone who would face with such problem.

Answer 3

Pichkasik is right.

In the GitHub website, under application setting, change "localhost" with "127.0.0.1" and it works for me.

Answer 4

In the documentation

Register a new application at GitHub Developers , set the callback URL to http://example.com/complete/github/ replacing example.com with your domain. This will generate a Client Key and a Client Secret.

Thing is, it's not http://example.com/complete/github/ for everyone.

Let's say you're developing locally and you have the following in your urls.py

path('social/', include('social_django.urls', namespace='social')),

then you'll need to add in your Authorization callback URL the following

http://localhost/social/complete/github/

You can then do something like this in your template

<a href="{% url 'social:begin' 'github' %}">GitHub</a>

Answer 5

I use http://127.0.0.1:8000 instead http://localhost:8000,and it works! enter image description here
