java HttpsURLConnection 实现https请求
直接使用类HttpsURLConnection访问Web页面 Java提供了一种非常简洁的方法来访问HTTPS网页，即使用类HttpsURLConnection、URL等。 类HttpsURLConnection似乎并没有提供方法设置信任管理器。 其实，HttpsURLConnection通过SSLSocket来建立与HTTPS的安全连接，SSLSocket对象是由SSLSocketFactory生成的。 对象，并设置其SSLSocketFactory对象 HttpsURLConnection httpsConn = (HttpsURLConnection)myURL.openConnection(); HttpsURLConnection conn; conn = (HttpsURLConnection)realUrl.openConnection(); conn.setSSLSocketFactory

Java HTTPS如何加载证书
最后，我们可以通过SSLContext类来创建一个HttpsURLConnection对象，从而实现与HTTPS服务器的通信。 sslContext.init(null, trustManagerFactory.getTrustManagers(), null);URL url = new URL(\https://example.com\HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();connection.setSSLSocketFactory(sslContext.getSocketFactory 然后，我们指定了目标HTTPS服务器的URL，并通过url.openConnection方法得到一个HttpsURLConnection对象。 最后，我们使用setSSLSocketFactory方法将SSLContext对象中的SocketFactory设置给HttpsURLConnection对象，从而实现与HTTPS服务器的通信。
