LinkedInHTTPError - 401 Client Error: Unauthorized

[planetcrypton]

I've just 'discovered' your python-linkedin library earlier today and set it up and tried to make it work with Django. But as soon as I set the authorization-code and want to retrieve the access-token with it, I get an LinkedInHTTPError : 401 Client Error: Unauthorized.

Here's my code; I'm using two views, one that redirects to the LinkedIn authorization page, and one for the return-url:

from django.shortcuts import render, render_to_response, redirect
from django.http import HttpResponse

from linkedin import linkedin

LI_API_KEY="123abc"
LI_API_SECRET="xyz123"
LI_RETURN_URL = 'http://127.0.0.1:8000/skills/linkedin-authcode/'

def signup(request):

    # Instantiate the developer authentication class
    authentication = linkedin.LinkedInAuthentication(LI_API_KEY, LI_API_KEY,
                                                     LI_RETURN_URL, linkedin.PERMISSIONS.enums.values())
    return redirect( authentication.authorization_url )

def linkedin_authcode(request):

    auth_code = request.GET.get('code', None)
    state = request.GET.get('state', None)

    authentication = linkedin.LinkedInAuthentication(LI_API_KEY, LI_API_KEY,
                                                     LI_RETURN_URL, linkedin.PERMISSIONS.enums.values())
    authentication.authorization_code = auth_code
    access_token = authentication.get_access_token()
    print access_token

    return HttpResponse("Linked Auth Code return page")

The debug-data I receive is:

Hello,

I believe it is related to #43.

According to Lee Fu, LinkedIn Developer responsible for the API, the problem is due to the latency between servers after obtaining the access token. He is suggesting the clients to put a slight delay after obtaining the access token.

When I put a 3 seconds delay before making .get_profile() call, I always end up getting my profile information.

All right. I believe to have read that there's a maximum time for using the retrieved authorization-code as well..?? Do have any experience with a maximum time?

No, I haven't but it is said by the doc that it will be alive and usable for 60 days. Probably, you will need to redirect the user to the authorization url again as long as it expires.

I'm still getting the 401 client-error, no matter how long I wait after receiving the authorization-code - either manually or by timer.sleep(). Though it only occurs when calling authentication.get_access_token() (as in my original example).

Might I experience another error..??

Sorry for wasting your time here! A plain old copy/paste error:

linkedin.LinkedInAuthentication(LI_API_KEY, LI_API_KEY,..)

should of course have been

linkedin.LinkedInAuthentication(LI_API_KEY, LI_API_SECRET,...)
