java - 读取代理java背后的https网页数据

Question

我想阅读安全网页数据说 https://www.paypal.com ，我在代理后面。我试过

System.setProperty("java.net.useSystemProxies","true");
System.setProperty("htttps.proxyHost","myproxyhost");
System.setProperty("https.proxyPort","443");

URL u = new URL("https://www.paypal.com");
URLConnection uc = u.openConnection();
uc.setDoOutput(true);

StringBuffer sbuf=new StringBuffer();
BufferedReader in = new BufferedReader(
new InputStreamReader(uc.getInputStream()));

String res = in.readLine();
System.out.println(" Response from paypal "+res);
while ((res = in.readLine()) != null){
       sbuf.append(res).append(",");
}
in.close();

System.out.println(" Total Data received  "+sbuf);

我一直收到 UnknownHostException，我正在通过 http 网站成功获取数据。我错过了什么吗？

谢谢，罗希特

您的 proxyHost 设置中有 3 个 T，即您使用的是 https 而不是 https。
