I've been trying to use httpclient4.0 to connect https server via socks
proxy, but it failed again and again.
My code is something like this:
KeyStore ks = loadCertFromFile(certFileName, passphrase);
X509TrustManager trustManager = getTrustManager(ks);
SocketFactory sf = new SocksSSLSocketFactory(getSSLContext(trustManager),
"10.64.69.40", 1080);
DefaultHttpClient httpclient = new DefaultHttpClient();
ClientConnectionManager ccm = httpclient.getConnectionManager();
SchemeRegistry schemeRegistry = ccm.getSchemeRegistry();
schemeRegistry.register(new Scheme("https", sf, portNumber));
httpResponse = httpclient.execute(httpHost, httpUriRequest);
public class SocksSSLSocketFactory implements SocketFactory {
private String proxyHost;
private int proxyPort;
private String userName;
private String passWd;
private final javax.net.ssl.SSLSocketFactory socketfactory;
public SocksSSLSocketFactory(SSLContext sslContext, String socksHost,
int socksPort) {
this(sslContext, socksHost, socksPort, null, null);
}
public SocksSSLSocketFactory(SSLContext sslContext, String socksHost,
int socksPort,
String userName, String passWd) {
this.socketfactory = sslContext.getSocketFactory();
proxyHost = socksHost;
proxyPort = socksPort;
this.userName = userName;
this.passWd = passWd;
}
public Socket createSocket() throws IOException {
return (SSLSocket) this.socketfactory.createSocket();
}
public Socket connectSocket(Socket sock,
String host,
int port,
InetAddress localAddress,
int localPort,
HttpParams params) throws IOException, UnknownHostException,
ConnectTimeoutException {
if (host == null) {
throw new IllegalArgumentException("Target host may not be
null.");
}
if (params == null) {
throw new IllegalArgumentException("Parameters may not be
null.");
}
InetSocketAddress epoint = new InetSocketAddress(host, port);
sock = getSocketConnected(epoint);
SSLSocket sslSocket =
(SSLSocket)this.socketfactory.createSocket(sock, host, port, false);
if ((localAddress != null) || (localPort > 0)) {
// we need to bind explicitly
if (localPort < 0) {
localPort = 0; // indicates "any"
}
InetSocketAddress isa =
new InetSocketAddress(localAddress, localPort);
sslSocket.bind(isa);
}
return sock;
}
public boolean isSecure(Socket sock) throws IllegalArgumentException {
if (sock == null) {
throw new IllegalArgumentException("Socket may not be null.");
}
// This check is performed last since it calls a method implemented
// by the argument object. getClass() is final in java.lang.Object.
if (sock.isClosed()) {
throw new IllegalArgumentException("Socket is closed.");
}
return false;
}
//generate the socket connected to socks4 proxy server
private Socket getSocketConnected(InetSocketAddress endpoint) throws
IOException {
Socket socket = new Socket(proxyHost, proxyPort);
InputStream in = socket.getInputStream();
OutputStream out = socket.getOutputStream();
out.write(4);
out.write(1);
out.write((endpoint.getPort() >> 8) & 0xff);
out.write((endpoint.getPort() >> 0) & 0xff);
out.write(endpoint.getAddress().getAddress());
if (userName != null)
{
try {
out.write(userName.getBytes("ISO-8859-1"));
} catch (java.io.UnsupportedEncodingException uee) {
assert false;
}
}
out.write(0);
out.flush();
byte[] data = new byte[8];
int n = readSocketReply(in, data);
if (n != 8) {
throw new SocketException("Reply from SOCKS server has bad
length: " + n);
}
if (data[0] != 0 && data[0] != 4) {
throw new SocketException("Reply from SOCKS server has bad
version");
}
SocketException ex = null;
switch (data[1]) {
case 90:
// Success!
break;
case 91:
ex = new SocketException("SOCKS request rejected");
break;
case 92:
ex = new SocketException("SOCKS server couldn't reach
destination");
break;
case 93:
ex = new SocketException("SOCKS authentication failed");
break;
default:
ex = new SocketException("Reply from SOCKS server contains
bad status");
break;
}
if (ex != null) {
in.close();
out.close();
throw ex;
}
return socket;
}
private int readSocketReply(InputStream in, byte[] data) throws
IOException {
int len = data.length;
int received = 0;
for (int attempts = 0; received < len && attempts < 3; attempts++) {
int count = in.read(data, received, len - received);
if (count < 0)
throw new SocketException("Malformed reply from SOCKS server");
received += count;
}
return received;
}
}
But I got java.net.SocketException:Socket is not connected when running:
httpResponse = httpclient.execute(httpHost, httpUriRequest);
Here is the log.

Actually I have connected to the proxy server in the connectSocket function,
I couldn't figure out why it reported this exception? (Why connection
shutdown after getconnection?)
Anyone can help me? Thank you in advance.
