Apache Oltu Instragram集成不返回access_token …为什么？
我正在开发Spring MVC + Apache Oltu + Instagram示例。 在这个例子中，我在https://www.instagram.com/developer/上创建了一个App，我得到了ClientId和Client_Secrete 。
使用此clientId和Client Secrete Secrete，调用Instagram Rest EndPoints 。 但是当调用REST EndPoint时，我收到以下错误：
SEVERE: Servlet.service() for servlet [appServlet] in context with path [/apache-oltu] threw exception [Request processing failed; nested exception is OAuthProblemException{error='invalid_request',

以下是我使用的细节：
AUTHORIZATION_URL = "https://api.instagram.com/oauth/authorize"; ACCESS_TOKEN_URL = "https://api.instagram.com/oauth/access_token";
我使用的范围是：
public_content follower_list comments relationships likes basic
代码执行时，我成功获得了authorizationCode，但看起来缺少令牌。 请帮忙。
我从URL调用Rest Endpoint： https ： //www.instagram.com/developer/endpoints/users/
我在下面使用的代码供参考：
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; } } }
以下是要进行的URL ::
https://api.instagram.com/oauth/authorize ？ scope = public_content + follower_list + comments + relations + likes + basic＆response_type = code＆redirect_uri = http％3A％2F％2Flocalhost％3A8080％2Fapache-oltu％2Finstagram％2Fredirect＆client_id = 40eb3e6047a249ddb7d9194765be9901
如果我使用ResponseType =“token”，那么我得到了
{"error_type": "OAuthForbiddenException", "code": 403, "error_message": "Implicit authentication is disabled"}
经过大量的试错法，我能够解决这个问题：
在请求访问令牌时，我应该使用以下内容：
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();
并随后的请求我将使用以下：
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();
这给了我坚实的回应：

经过更多google发现： OAuthProblem，缺少参数access_token
