java – 为什么我的SOCKS代理代码抛出SocketException：来自SOCK

为什么我的SOCKS代理代码抛出SocketException：来自SOCKS服务器的格式错误的回复？我试图在URLConnection或其他设置,但这不起作用.唯一有用的东西 – chilkat lib,但它是商业的.那么,我如何通过ASOCKS代理发出http请求呢？也许存在一些免费的lib？

例如,该代码：

SocketAddress addr = new InetSocketAddress(proxy_ip,proxy_port);
    Proxy proxy = new Proxy(Proxy.Type.SOCKS,addr);
    Socket socket = new Socket(proxy);
    InetSocketAddress dest = new InetSocketAddress("google.com",80);
    try {
        socket.connect(dest);
    } catch (IOException ex) {
        Logger.getLogger(CheckProxy.class.getName()).log(Level.SEVERE,null,ex);
    }

抛出异常：

java.net.SocketException: Malformed reply from SOCKS server
at java.net.SocksSocketImpl.readSocksReply(Unknown Source)
at java.net.SocksSocketImpl.connect(Unknown Source)
at java.net.Socket.connect(Unknown Source)
at java.net.Socket.connect(Unknown Source)
at proxychecker.CheckProxy.SocksCheck(CheckProxy.java:86)

第86行是“socket.connect(dest);”
