[HttpClient 4] local socket port

[Wolfram Alpha <wo...@googlemail.com>]

Hi

I'm using the Apache HttpClient 4.1.2 and I want to get the local port of
the underlying socket. I have not found a reasonable way to get the
port-number without changing a lot of the httpclient code, which I don't
want to do.

Is there realy no easy way to get the port-number?

Any suggestions are appreciated!

Thanks

Thank you for your solutions! Both are working as expected and I have
already implemented the solution with the ClientConnectionOperator.

Custom ClientConnectionOperator is still the way to go if one wants to
exert full control over the process of connection initialization.
However, I just figured there is probably a much simpler way to get the
endpoint details of an active connection

---
DefaultHttpClient httpclient = new DefaultHttpClient();
httpclient.addRequestInterceptor(new HttpRequestInterceptor() {
    
    public void process(
            HttpRequest request, HttpContext context) throws
HttpException, IOException {
        HttpInetConnection conn = (HttpInetConnection)
context.getAttribute(
                ExecutionContext.HTTP_CONNECTION);
        System.out.println(conn.getLocalAddress() + ":" +
conn.getLocalPort());
        System.out.println(conn.getRemoteAddress() + ":" +
conn.getRemotePort());
    }
});
---

Hope this helps

Oleg

Your problem seems similar to mine. Oleg recommended extending the
DefaultClientConnectionOperator class to add the socket attribute to
the context. Something like:

class MyClientConnectionOperator extends DefaultClientConnectionOperator {

    public MyClientConnectionOperator(SchemeRegistry schemes) {
        super(schemes);
    }

    @Override
    protected void prepareSocket(
            final Socket sock,
            final HttpContext context,
            final HttpParams params) throws IOException {
        super.prepareSocket(sock, context, params);
        context.setAttribute("sock-port", sock.getLocalPort());
    }

};
