使用具有多個NIC的Axis2服務器獲取客戶端綁定的IP地址

Question

我正在通過存根連接到Axis 2服務器：

MyServiceStub fcc = new MyServiceStub(url);

建立連接后，由於我在不同子網的計算機上配置了不同的IP地址，因此我想知道與服務器建立連接的地址是什么。

例如，如果我有一台以這種方式配置的2個NIC和IP地址的機器：

eth0 ---> 192.165.0.1
eth1 ---> 10.0.3.1

並且我在IP：10.0.3.33上有一個Axis服務器，一旦建立連接，如何知道綁定的IP地址？

如何獲得連接的客戶端IP地址（在這種情況下： 10.0.3.1 ）？

Answer 1

也許你可以嘗試這樣的事情

request.getHeader("url");
String ipAddress = request.getHeader("X-FORWARDED-FOR");
   if (ipAddress == null) {
        ipAddress = request.getRemoteAddr();
   }

Answer 2

如果使用https協議來調用axis2 Web服務，則可以實現自己的SecureProtocolSocketFactory，如下所示：

public class CustomProtocolSocketFactory implements SecureProtocolSocketFactory {
    private static final Logger logger = Logger.getLogger("trace");
    InetAddress localAddress=null;
    SSLContext ctx=null;
    Socket socket=null;
    public CustomProtocolSocketFactory(SSLContext ctx) {
        this.ctx = ctx;
    }
    public CustomProtocolSocketFactory(SSLContext ctx, InetAddress localAddress) {
        this.ctx = ctx;
        this.localAddress=localAddress;
    }
    public CustomProtocolSocketFactory(SSLContext ctx, InetAddress localAddress, Socket socket) {
        this.ctx = ctx;
        this.localAddress=localAddress;
        this.socket=socket;
    }
    @Override
    public Socket createSocket(String host, int port, InetAddress localAddress, int localPort)
            throws IOException, UnknownHostException {
        logger.debug("createSocket(String host, int port, InetAddress localAddress, int localPort)");
        return ctx.getSocketFactory().createSocket(host, port, localAddress, localPort);
    }
    @Override
    public Socket createSocket(String host, int port, InetAddress localAddress, int localPort,
            HttpConnectionParams params) throws IOException, UnknownHostException, ConnectTimeoutException {
        logger.debug("createSocket(String host, int port, InetAddress localAddress, int localPort,HttpConnectionParams params)");
        if (params == null) {
            throw new IllegalArgumentException("Parameters may not be null");
        }
        int timeout = params.getConnectionTimeout();
        SocketFactory socketfactory = ctx.getSocketFactory();
        if (timeout == 0) {
            if(this.localAddress!=null){
                return socketfactory.createSocket(host, port, this.localAddress, localPort);
            }
            else{
                return socketfactory.createSocket(host, port, localAddress, localPort);
            }
        } else {
            Socket socket = socketfactory.createSocket();
            if(this.localAddress!=null){
                SocketAddress localaddr = new InetSocketAddress(this.localAddress, localPort);
                SocketAddress remoteaddr = new InetSocketAddress(host, port);
                socket.bind(localaddr);
                socket.connect(remoteaddr, timeout);
                return socket;
            }
            else{
                SocketAddress localaddr = new InetSocketAddress(localAddress, localPort);
                SocketAddress remoteaddr = new InetSocketAddress(host, port);
                socket.bind(localaddr);
                socket.connect(remoteaddr, timeout);
                return socket;
            }
        }
    }
    @Override
    public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
        if(localAddress!=null){
            logger.debug("createSocket(String host, int port) localAddress not null");
            return createSocket(host, port, localAddress, 0);
        }
        else{
            logger.debug("createSocket(String host, int port)");
            return ctx.getSocketFactory().createSocket(host, port);
        }
    }
    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose)
            throws IOException, UnknownHostException {
        logger.debug("createSocket(Socket socket, String host, int port, boolean autoClose)");
        return ctx.getSocketFactory().createSocket(socket, host, port, autoClose);
    }
}

您可以將套接字與InetAddress localAddress綁定並使用如下方式：

proxy._getServiceClient().getOptions().setProperty(HTTPConstants.CUSTOM_PROTOCOL_HANDLER,
                            new Protocol("https",(ProtocolSocketFactory)new CustomProtocolSocketFactory(context,localAddress),port));
