我在 google appengine 上有以下代码来测试 twitter 凭据是否使用 twitter4j 有效

public void doGet(HttpServletRequest req, HttpServletResponse resp) {
    String Test = "Testing Twitter4J";
    try {

        ConfigurationBuilder confbuilder  = new ConfigurationBuilder();
        confbuilder.setOAuthAccessToken("A") 
        .setOAuthAccessTokenSecret("B") 
        .setOAuthConsumerKey("C") 
        .setOAuthConsumerSecret("D"); 
        Twitter twitter = new TwitterFactory(confbuilder.build()).getInstance(); 

        //Status status = twitter.updateStatus("Working lunch today");
        User user = twitter.verifyCredentials();
        Test = "Successfully updated the status to [" + user.getScreenName() + "].";

    } catch (TwitterException e) {
        Test =  "no";
    }
    try {
        resp.getOutputStream().write(Test.getBytes());
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    return;
}

如果凭据有效,它将按预期工作。如果我撤销访问权限导致凭据无效,我会收到应用引擎错误:

Uncaught exception from servlet
twitter4j.TwitterRuntimeException: 401:Authentication credentials (https://dev.twitter.com/pages/auth) were missing or incorrect. Ensure that you have set valid consumer key/secret, access token/secret, and the system clock is in sync.
message - Invalid or expired token
code - 89

TwitterException{exceptionCode=[93f2523c-8b74a4e3], statusCode=401, message=Invalid or expired token, code=89, retryAfter=-1, rateLimitStatus=null, version=3.0.3}

来自“用户用户 = twitter.verifyCredentials();” 线。我期待从 javadoc 中抛出 TwitterException:http: //twitter4j.org/javadoc/twitter4j/api/UsersResources.html#verifyCredentials() 但似乎我得到了 TwitterRuntimeException。为什么?我在 javadocs 中找不到任何关于 TwitterRuntimeException 的注释。

对我来说,解决方案如下:

  • 转到您的推特应用程序
  • 选择设置选项卡
  • 在应用程序类型 - 访问 - 选择最后一个选项读取、写入和访问直接消息

如果这不能解决问题,请尝试添加回调 URL。你可以在这里放任何网址就可以了。
