Java 抄写1.3 linkedin API共享请求返回401-未经授权

我正试图从我的web应用程序向我的linkedin发送共享内容，但看起来我做错了什么

这是我的java代码：

String payload = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"+
    "<share>" +
        "<comment>testing</comment>" +
        "<visibility><code>anyone</code></visibility>" +
        "</share>";

String PROTECTED_RESOURCE_URL = "http://api.linkedin.com/v1/people/~/shares";
        OAuthService service = new ServiceBuilder()
        .provider(LinkedInApi.class)
        .apiKey("XXXXXXXXX")
        .apiSecret("XXXXXXXXX")
        .debug()
        .build();
Scanner in = new Scanner(System.in);
Token requestToken = service.getRequestToken();

// here is for enter the confirmation code while i'm use ooB, use callback in future
System.out.println("Now go and authorize Scribe here:");
System.out.println(service.getAuthorizationUrl(requestToken));
System.out.println("And paste the verifier here");
System.out.print(">>");
Verifier verifier = new Verifier(in.nextLine());

Token accessToken = service.getAccessToken(requestToken, verifier);
OAuthRequest request = new OAuthRequest(Verb.POST, PROTECTED_RESOURCE_URL);
request.addPayload(payload);
service.signRequest(accessToken, request);
Response response = request.send();

所有这些看起来都在调试控制台中工作，但当我尝试打印响应正文时，我得到以下结果：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<error>
  <status>401</status>

我怎样才能解决这个问题？

谢谢Pablo， 在这种情况下，调试模式对我没有帮助，但通过一些搜索，我发现了问题：

为类似这样的Post请求添加标题

    request.addHeader("Content-Length", Integer.toString(payload.length()));  
    request.addHeader("Content-Type", "text/xml");

您打开了

debug

模式。使用该标志，您的控制台显示打印有用的信息，您可以在的论坛中发布并获得帮助。感谢您添加答案，我花了2个小时调试相同的错误，直到发现此错误。太多了！可能节省了我几个小时。
