通过https获取XML数据：//

Question

我的代码适用于http，但不适用于https。以下是错误消息，即时得到我的呼唤的getMessage（）在IOException异常：

java.net.SocketException异常：地址家族不受协议

支持我的继承人代码：

您列出的方法仅适用于http。让你的程序识别https url并使用下面的一些字母。

/** 
* Initialize the HTTP/S connection (if needed) 
* 
* @param keystoreFile the full path of the keystore file 
* @param keystorePass the password for the keystore file 
*/ 
private void initHttps(String keystoreFile, String keystorePass) 
{ 
    // check if the URL uses HTTP/S 
    if (url.toLowerCase().startsWith(HTTPS_PROTOCOL)) 
    { 
     print("Initializing HTTP/S protocol..."); 
     // set the system properties needed for HTTP/S 
     System.setProperty("javax.net.ssl.keyStore", keystoreFile); 
     System.setProperty("javax.net.ssl.keyStorePassword", keystorePass); 
     System.setProperty("javax.net.ssl.keyStoreType", "JKS"); 
     System.setProperty("javax.net.ssl.trustStore", keystoreFile); 
     System.setProperty("javax.net.ssl.trustStorePassword", keystorePass); 
     System.setProperty("javax.protocol.handler.pkgs", 
      "com.sun.net.ssl.internal.www.protocol"); 
     //int addProvider = Security.addProvider(new  com.sun.net.ssl.internal.ssl.Provider()); 
     HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() 
     { // fix a HTTP/S handshake issue 
      public boolean verify(String hostName, SSLSession session) 
      { // Verify that the host name is acceptable 
       return true; 
      } 
     }); 
    } 
}
