Jasha Joachimsthal commented on OLTU-170:
-----------------------------------------
LinkedIn expects an HTTP POST with the parameters in the URL to obtain the
access token. Your oAuthClientRequest looks fine.
{code:java}
final OAuthAccessTokenResponse accessTokenResponse =
oAuthClient().accessToken(oAuthClientRequest, OAuth.HttpMethod.POST);
{code}
> Exception when obtaining access token for LINKED IN

> Issue Type: Bug
> Components: oauth2-client
> Affects Versions: oauth2-1.0.0
> Environment: Win7/JDK8.31
> Reporter: Constantin Mitocaru
>
> After obtaining the code I make this call:

> OAuthClientRequest request = OAuthClientRequest
> .tokenProvider(OAuthProviderType.LINKEDIN)
> .setGrantType(GrantType.AUTHORIZATION_CODE)
> .setClientId(resources.getString("in.app-key"))
> .setClientSecret(resources.getString("in.app-secret"))
> .setRedirectURI(receivingUrl)
> .setCode(code)
> .buildQueryMessage();
> String uri = request.getLocationUri();
> System.out.println("IN.uri.auth_token="+uri);
> OAuthClient oAuthClient = new OAuthClient(new
> URLConnectionClient());
> OAuthJSONAccessTokenResponse oAuthResponse =
> oAuthClient.accessToken(request, OAuthJSONAccessTokenResponse.class);
>
> {code}
> I get this error:
> {code}
> java.io.IOException: OAuthProblemException{error='unsupported_response_type',
> description='Invalid response! Response body is not application/json
> encoded', uri='null', state='null', scope='null', redirectUri='null',
> responseStatus=0, parameters={}}
> {code}
> I know that the call is right because I put the produced link directly and I
> got this output:
