【问题描述】：

我正在尝试根据How do a send an HTTPS request through a proxy in Java?使用代理访问https网页

但我遇到了一个奇怪的问题：HttpsURLConnection 忽略了 setSSLSocketFactory 方法。 这是我的代码：

HttpsURLConnection connection = (HttpsURLConnection) new URL("https://www.google.com").openConnection();
connection.setSSLSocketFactory(new SSLTunnelSocketFactory("127.0.0.1", 8089));

这是 SSLTunnelSocketFactory 类：

class SSLTunnelSocketFactory extends SSLSocketFactory 
    public SSLTunnelSocketFactory(String proxyIpAddress, int proxyPort) 
        System.out.println("calling SSLTunnelSocketFactory");
    
    @Override
    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException, UnknownHostException 
        System.out.println("calling createSocket");
    

    @Override
    public Socket createSocket(String s, int i) throws IOException,
            UnknownHostException 
        throw new NotImplementedException();
    

    @Override
    public Socket createSocket(String s, int i, InetAddress inetAddress,
                               int i2) throws IOException,
            UnknownHostException 
        throw new NotImplementedException();
    

    @Override
    public Socket createSocket(InetAddress inetAddress,
                               int i) throws IOException 
        throw new NotImplementedException();
    

    @Override
    public Socket createSocket(InetAddress inetAddress, int i,
                               InetAddress inetAddress2,
                               int i2) throws IOException 
        throw new NotImplementedException();
    

    @Override
    public String[] getDefaultCipherSuites() 
        throw new NotImplementedException();
    

    @Override
    public String[] getSupportedCipherSuites() 
        throw new NotImplementedException();
    

这是输出：

calling SSLTunnelSocketFactory
Exception in thread "main" java.lang.RuntimeException: java.net.ConnectException: Connection timed out: connect

可以看到“调用createSocket”没有打印出来，出现超时异常。 这意味着 setSSLSocketFactory 方法被忽略，这不应该发生。

你能帮我解决这个问题吗？

问题解决了吗？如果是这样，请告诉我们解决方案

【参考方案1】：

好像你需要设置 连接.setDoInput(true); 连接.setDoOutput(true);
