java测试https型url是否能建立连接

// 创建URL对象
URL myURL = new URL
// 创建HttpsURLConnection对象，并设置其SSLSocketFactory对象
HttpsURLConnection httpsConn = (HttpsURLConnection) myURL
.openConnection();
// 取得该连接的输入流，以读取响应内容
InputStreamReader insr = new InputStreamReader(httpsConn
.getInputStream());
// 读取服务器的响应内容并显示
int respInt = insr.read();
while (respInt != -1) {
System.out.print((char) respInt);
respInt = insr.read();
}
