how to do request in HttpClient?

I have write REST wed service using jersey framework and java. If user want to request HttpGet in curl he need to write like:

curl -u username:password -H "Content-Type:application/...." http://localhost:8080/project/user

Now, I am implement android which will call web service. Do anyone know how to use HttpClient in android to call web service? How to set username and password in HttpClient in order to match with curl command -u username:passw开发者_运维问答ord?

thanks

    }


}
}

Hope this code will help

@sudo try this simple code

HttpURLConnection conn = null;

    try {
        // The formated URL will be "http://www.androidcoder.org:80".
        URL url = new URL(String.format("http://%s:%d/%s", mIpAddress, mPort, mSubPage));
        conn = (HttpURLConnection) url.openConnection();

        conn.setRequestMethod("GET");
        conn.setRequestProperty("Content-length", "0");
        conn.setUseCaches(false);
        conn.setAllowUserInteraction(false);
        conn.setConnectTimeout(TIMEOUT);
        conn.setReadTimeout(TIMEOUT);

        // NOTE: Below is used to perform the http authentication. It is working in JAVA but not
        // always working in Android platform.

        // Set to use the default HTTP authentication. Working in JAVA, but not working in
        // Android.
        Authenticator.setDefault(new Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("user1", "pass1".toCharArray());
            }
        });
        conn.connect();

        System.out.println(conn.getResponseCode()); // <-- The request will stop here if running
                                                    // in Android.
        System.out.println(conn.getResponseMessage());

        printOutput(conn);

    } catch (MalformedURLException e) {
        // TODO: Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // Operation timed out.
        System.out.println(e.getMessage());
        e.printStackTrace();
    } finally {
        if (conn != null) {
            conn.disconnect();
            conn = null;
        }
    }
}
