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

Question

我能够跟随 oauth 舞蹈直到最后一步：我有一个请求令牌，在用户在浏览器中对应用程序进行身份验证后，oauth 验证程序会发送回我的 Android-app。不幸的是，我无法获得最终访问令牌。这就是我在最后一步中尝试做的事情：

// 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) 是上面代码的最后一行。在 JDKHttpClient.java 的第 104 行中，它试图在 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。调试输出类似于

我只是稍微更改了凭据，因为我不想发布我网站的凭据。

我希望上述连接能够成功，并进一步归还我的 wordpress api 的访问令牌。当我在 Postman 中发送相同的凭据时，请求成功。那么问题出在哪里，当我使用 scribejava 时？是因为 scribejava 在请求 header 中发送了 oauth_verifier 而在 Postman 中你可以将它作为 url 参数发送吗？

根据日志：

Caused by: android.os.NetworkOnMainThreadException

你在主线程调用服务api方法，尝试使用AsyncTask来处理网络请求。
