使用scribejava请求访问令牌时出现http连接错误oauth1.0a使用scribejava

Question

我能够遵循oauth跳舞到最后一步： 我有一个请求令牌，并且一个oauth验证者会发送回我的A​​ndroid应用用户在浏览器中验证应用程序后。不幸的是，我无法获得最终访问令牌。这就是我在这最后一步所要做的：

// use the parameter your API exposes for the verifier 
String oauthVerifier = uri.getQueryParameter("oauth_verifier"); 

// get requestToken from shared preferences 
SharedPreferences sharedPref = this.getPreferences(Context.MODE_PRIVATE); 
OAuth1RequestToken requestToken = new OAuth1RequestToken(
     sharedPref.getString("WP_OAuthToken",""), 
     // sharedPref.getString("WP_OAuthTokenSecret","") 
     oauthVerifier 
); 

// request accessToken from API 
OAuth1AccessToken accessToken = null; 
try { 
    accessToken = service.getAccessToken(requestToken, oauthVerifier); 
} ... 

最后一行在这里不起作用。 logcat告诉我

其中.LoginActivity.onResume(LoginActivity.java:132)是上面代码中的最后一行。在JDKHttpClient.java的第104行中，试图在final HttpURLConnection connection = (HttpURLConnection) new URL(completeUrl).openConnection();上运行connection.connect();。当我尝试调试错误时，这是​​我的应用程序崩溃的地方。调试输出是类似的

我只是稍微改变了凭据，因为我不希望我的网站发布凭据。

我期望上面的连接是成功的，此外还要为我的wordpress API返回访问令牌。当我在Postman中发送相同凭证时，请求成功。那么当我使用scribejava时，问题出在哪里？ 是否因为scribejava在请求头中发送了oauth_verifier，并且在Postman中可以将它作为url参数发送？

根据日志：

Caused by: android.os.NetworkOnMainThreadException 

调用主线程上的服务API方法，尝试使用的AsyncTask来处理网络请求。
