X509TrustManager信任SSL证书

做个笔记

// TrustManager[] tm = {new MyX509TrustManager ()};
// SSLContext sslContext = SSLContext.getInstance(“SSL”,“SunJSSE”);
// sslContext.init(null, tm, new java.security.SecureRandom());
//
// //从上述SSLContext对象中得到SSLSocketFactory对象
// SSLSocketFactory ssf = sslContext.getSocketFactory();
//
// //创建HttpsURLConnection对象，并设置其SSLSocketFactory对象
// URL url=new URL(ENDPOINT);
// HttpsURLConnection httpsConn = (HttpsURLConnection)url.openConnection();
// httpsConn.setSSLSocketFactory(ssf);

	// 获取一个SSLContext实例

// 该方法检查服务器的证书，若不信任该证书同样抛出异常。通过自己实现该方法，可以使之信任我们指定的任何证书。
// 在实现该方法时，也可以简单的不做任何处理，即一个空的函数体，由于不会抛出异常，它就会信任任何证书。
