android - 在android中使用scribe OAuth时出现无效的验证码格式错误

Question

我正在使用 scribe oAuth 库来实现 Facebook oAuth 登录，使用
this例子

I have set www.example.com (a valid ur) in Site URL and Mobile Web Url in facebook application setting

这是我在android中的代码

OAuthService service = new ServiceBuilder()
                                        .provider(FacebookApi.class)
                                        .apiKey(apiKey)
                                        .apiSecret(apiSecret)
                                        .callback("http://www.example.com/")
                                        .build();
          Scanner in = new Scanner(System.in);

          System.out.println("=== " + NETWORK_NAME + "'s OAuth Workflow ===");
          System.out.println();

          // Obtain the Authorization URL
          System.out.println("Fetching the Authorization URL...");
          String authorizationUrl = service.getAuthorizationUrl(EMPTY_TOKEN);
          System.out.println("Got the Authorization URL!");
          System.out.println("Now go and authorize Scribe here:");
          System.out.println(authorizationUrl);
          System.out.println("And paste the authorization code here");
          System.out.print(">>");
          String val = new String();
          if(in.hasNextLine())
           val = in.nextLine();
          System.out.println("VALUE"+val);
          Verifier verifier = new Verifier(val);
          System.out.println();

          // Trade the Request Token and Verfier for the Access Token
          System.out.println("Trading the Request Token for an Access Token...");
          Token accessToken = service.getAccessToken(EMPTY_TOKEN, verifier);
          System.out.println("Got the Access Token!");
          System.out.println("(if your curious it looks like this: " + accessToken + " )");
          System.out.println();

但我遇到以下错误

Caused by: org.scribe.exceptions.OAuthException: Response body is incorrect. Can't extract a token from this: '{"error":{"message":"Invalid verification code format.","type":"OAuthException"}}'

如果我将其作为独立程序运行，那么它会要求我提供一些授权码 但我真的不知道该放什么。

这里是代码行

Scanner in = new Scanner(System.in);
Verifier verifier = new Verifier(in.nextLine());
System.out.println();

尝试在回调 url 的末尾添加斜线。我花了几个小时解决这个问题!!!感谢this post我找到了答案!
