我从这个链接使用XML-RPC服务器和客户端与android应用程序：http://www.codeforest.net/how-to-build-php-xml-rpc-server-client-and-android-app 通信是通过HTTP进行的。你能解释一下我必须在 Android 代码中更改什么以及在哪里通过 HTTPS 进行通信吗？谢谢(我读了很多关于stackoverflow的文章，但我不知道如何在我的安卓代码中使用它(
这是我的解决方案，它工作正常：
//In class XMLRPCClient
public XMLRPCClient(URI uri) {
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", new PlainSocketFactory(),
80));
registry.register(new Scheme("https", new EasySSLSocketFactory(), 443));
postMethod = new HttpPost(uri);
postMethod.addHeader("Content-Type", "text/xml");
// WARNING
// I had to disable "Expect: 100-Continue" header since I had
// two second delay between sending http POST request and POST body
httpParams = postMethod.getParams();
HttpProtocolParams.setUseExpectContinue(httpParams, false);
this .client = new DefaultHttpClient(
new ThreadSafeClientConnManager(httpParams, registry),
httpParams);
}
并且必须添加到org.xmlrpc.android 2类EasySSLSocketFactory和EasyX509TrustManager
EasySSLSocketFactory：

它应该可以很好地与https一起使用。您只需要将 URL 更改为以 https 开头即可。
注意：如果 SSL 证书不是受信任的证书，则可能需要编写逻辑来处理此问题。但是，如果证书随您的设备一起使用，则无需进行其他更改。
