GAE網址提取服務爲HTTPS

Question

我的應用程序拋出這個錯誤：

[INFO] Caused by: java.lang.ClassCastException: com.google.apphosting.utils.security.urlfetch.URLFetchServiceStreamHandler$Connection cannot be cast to javax.net.ssl.HttpsURLConnection 
[INFO] at info.modprobe.browserid.Verifier.verify(Verifier.java:76) 

而導致錯誤的代碼是：

 URL verifierURL = new URL(this.url); 
     String response = ""; 
     HttpsURLConnection connection = (HttpsURLConnection) verifierURL 
       .openConnection(); // error here... 
     connection.setRequestMethod("POST"); 
     connection.setRequestProperty("Content-Type", 
       "application/json; charset=utf-8"); 
     connection.setDoOutput(true); 

當嘗試使用此library做Mozilla的個人驗證。我想知道自從GAE網址提取服務支持HTTPS後會出現什麼問題。

Answer 1

嘗試

HttpURLConnection connection = (HttpURLConnection) verifierURL.openConnection(); 

，而不是

HttpsURLConnection connection = (HttpsURLConnection) verifierURL.openConnection(); 

它將創建它所需要的下方，也爲HTTPS，但不要強迫劇組到HTTPS，因爲它使用了類（URLFetchServiceStreamHandler $連接）taht擴展HttpURLConnection但不HttpsURLConnection
