I am developing a Spring MVC + Apache Oltu + Instagram example. In this example I created an App on https://www.instagram.com/developer/ and I got the ClientId and Client_Secrete.
Uisng this clientId and Client Secret, calling the Instagram Rest EndPoints. But when calling either the REST EndPoint I am getting the below error:
SEVERE: Servlet.service() for servlet [appServlet] in context with path [/apache-oltu] threw exception [Request processing failed; nested exception is OAuthProblemException{error='invalid_request', description='Missing parameters: access_token', uri='null', state='null', scope='null', redirectUri='null', responseStatus=0, parameters={}}] with root cause

Following are the details I used:
AUTHORIZATION_URL = "https://api.instagram.com/oauth/authorize";
ACCESS_TOKEN_URL = "https://api.instagram.com/oauth/access_token";
The scopes which I used are:
public_content follower_list comments relationships likes basic
When code is executing, I am getting the authorizationCode successfully, but looks like token is missing.
I am calling the Rest Endpoint from URL: https://www.instagram.com/developer/endpoints/users/
The code which I used below for reference:
private String getAccessToken(String authorizationCode) throws OAuthSystemException, OAuthProblemException {
OAuthClientRequest request = OAuthClientRequest
.tokenLocation(ACCESS_TOKEN_URL)
.setGrantType(GrantType.AUTHORIZATION_CODE)
.setClientId(CLIENT_ID)
.setClientSecret(CLIENT_SECRET)
.setRedirectURI(REDIRECT_URL)
.setCode(authorizationCode)
.buildQueryMessage();
OAuthClient oAuthClient = new OAuthClient(new URLConnectionClient());
GitHubTokenResponse oAuthResponse = oAuthClient.accessToken(request, GitHubTokenResponse.class);
request= new OAuthBearerClientRequest("https://api.instagram.com/v1/users/self/").
setAccessToken(oAuthResponse.getAccessToken()).
buildQueryMessage();
System.out.println("REQUEST_BODY : "+request.getBody());
OAuthClient client = new OAuthClient(new URLConnectionClient());
OAuthResourceResponse resourceResponse= client.resource(request, "GET", OAuthResourceResponse.class);
if (resourceResponse.getResponseCode()==200){
logger.debug("HTTP OK");
System.out.println(resourceResponse.getBody());
return resourceResponse.getBody();
}
else{
System.out.println("Could not access resource: " + resourceResponse.getResponseCode()
+ " " + resourceResponse.getBody());
return null;
}
}
}
The following is the URL which is going ::
https://api.instagram.com/oauth/authorize? scope=public_content+follower_list+comments+relationships+likes+basic& response_type=code& redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Fapache-oltu%2Finstagram%2Fredirect& client_id=40eb3e6047a249ddb7d9194765be9901
If I used ResponseType="token" then I get the
{"error_type": "OAuthForbiddenException", "code": 403, "error_message": "Implicit authentication is disabled"}
After lots of trial and error method, I was able to resolve this issue:
While making request for the access token I should be using the below:
OAuthClientRequest request = OAuthClientRequest
.authorizationLocation(AUTHORIZATION_URL)
.setClientId(CLIENT_ID)
.setRedirectURI(REDIRECT_URL)
.setResponseType(ResponseType.CODE.toString())
.setScope("public_content follower_list comments relationships likes basic")
.buildQueryMessage();
and with the subsequent request I will be using the below:
OAuthClientRequest request = OAuthClientRequest
//.authorizationProvider(OAuthProviderType.INSTAGRAM)
.tokenLocation(ACCESS_TOKEN_URL)
.setGrantType(GrantType.AUTHORIZATION_CODE)
.setClientId(CLIENT_ID)
.setClientSecret(CLIENT_SECRET)
.setRedirectURI(REDIRECT_URL)
.setCode(authorizationCode)
.buildBodyMessage();
and this gives me the solid Response:
{"data": {"id": "3159574895", "username": "Raj", "profile_picture": "https://scontent.cdninstagram.com/t51.2885-19/s150x150/19367511_329283184160313_6318737005198966784_a.jpg", "full_name": "Raj", "bio": "Wish me on 25th-Dec\nLove to code !! \nEngineer by my choice !!\nLove to drive !! \ud83d\ude0b\ud83d\ude0a", "website": "", "is_business": false, "counts": {"media": 14, "follows": 18, "followed_by": 51}}, "meta": {"code": 200}}
After more google found : OAuthProblem, missing parameter access_token
