Access denied when trying to retrieve connections #121

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Would it be possible to support member permissions like "r_network" to be able 
to retrieve a user's connections?  I can retrieve basic profile information, 
but cannot retrieve the connections, I am getting "access denied".

For example, instead of using this URL to retrieve the token:

https://api.linkedin.com/uas/oauth/requestToken

I would like to be able to use this URL which includes multiple member 
permissions:

https://api.linkedin.com/uas/oauth/requestToken?scope=r_network+w_messages+rw_nu
s+rw_groups

Please refer to this thread on LinkedIn developer's site to see what I'm 
talking about:

I proposed these two change to the implementation to solve the problems 
encountered with scope...

Then use  instead of simply:
       LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService(linkedInApiKey, linkedInSecretKey)
       LinkedInRequestToken requestToken = oauthService.getOAuthRequestToken(callbackUrl);

      LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService(linkedInApiKey, linkedInSecretKey)
       LinkedInRequestToken requestToken = oauthService.getOAuthRequestToken(callbackUrl, scope);

The scope is defined with a string like (See 
http://oodlestechnologies.com/blogs/Recent-changes-in-LinkedIn-API for more 
info)
scope = "r_fullprofile r_network";

Hopes it helps

In the methods listed above in the overridden code, it says override 
getOAuthAccessToken(), which is incorrect.  You need to override 
getOAuthRequestToken() and getOAuthRequestToken(callbackurl)...

I was able to get this to work .
I did not modify original source, but what I did was, 
1) created my own MyLinkedInOAuthServiceFactory.java  ( could not extend theirs 
because of constructor error )
2) created my own MyLinkedInOAuthServiceImpl.java - extended from their  
LinkedInOAuthServiceImpl
3) created my own MyLinkedInOAuthService.java - extended from their 
LinkedInOAuthService 

Attached is my source for reference ..
