为什么Apache Oltu Instragram集成不返回access_token

问题描述 投票：0回答：1

我正在开发Spring MVC + Apache Oltu + Instagram示例。在此示例中，我在[https://www.instagram.com/developer/上创建了一个应用程序，并获得了ClientId和Client_Secrete。

使用此clientId和Client Secret，调用Instagram Rest EndPoints。但是，当调用任一REST EndPoint时，出现以下错误：

SEVERE: Servlet.service() for servlet [appServlet] in context with path [/apache-oltu] threw exception [Request processing failed; nested exception is OAuthProblemException{error='invalid_request', description='Missing parameters: access_token', uri='null', state='null', scope='null', redirectUri='null', responseStatus=0, parameters={}}] with root cause

以下是我使用的详细信息：

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

执行代码时，我成功获取了AuthorizationCode，但是好像缺少令牌。

我正在从URL呼叫其余端点：https://www.instagram.com/developer/endpoints/users/

下面我用作参考的代码：

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;
        }
    } 
}

以下是正在使用的URL ::

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

如果我使用ResponseType =“ token”，则会得到

{"error_type": "OAuthForbiddenException", "code": 403, "error_message": "Implicit authentication is disabled"}

经过大量的尝试和错误方法，我能够解决此问题：

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();

以及随后的请求，我将使用以下内容：

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();

这给了我可靠的答复：

{"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}}
