这是用JAVA的SOCKET类实现的HTTP CLIENT的代码。通过它可以让原来很头疼的事情现在轻松的解决

package org.apache.commons.httpclient.demo;

import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;

public class SubmitHttpForm {

    private static String url ="http://localhost:8080/validatorStrutsApp/userInfo.do";

    public static void main(String[] args) {

        //Instantiate an HttpClient
        HttpClient client = new HttpClient();

        //Instantiate a GET HTTP method
        HttpMethod getmethod = new GetMethod(url);
        PostMethod postmethod = new PostMethod("/search2005.php");

        //Define name-value pairs to set into the QueryString
        NameValuePair nvp1 = new NameValuePair("firstName", "fname");
        NameValuePair nvp2 = new NameValuePair("lastName", "lname");
        NameValuePair nvp3 = new NameValuePair("email", "[e-mail]");

        getmethod.setQueryString(new NameValuePair[] {nvp1, nvp2, nvp3});

        try {
            int statusCode = client.executeMethod(getmethod);

            System.out.println("QueryString>>> " + getmethod.getQueryString());
            System.out.println("Status Text>>> " + HttpStatus.getStatusText(statusCode));

            //Get data as a String
            System.out.println(getmethod.getResponseBodyAsString());

            //OR as a byte array
            byte[] res = getmethod.getResponseBody();

            //write to file
            FileOutputStream fos = new FileOutputStream("donepage.html");
            fos.write(res);

            //release connection
            getmethod.releaseConnection();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
