Socket Java JSP .net Web

首先建立一个web工程

准备连个jsp文件试试正常的流程

testpost.jsp数据提交页面

<%@ page language="java" pageEncoding="GBK"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<body>
<form method="post" action="testpostresult.jsp">
    This is my JSP page. <br><br>
    <input name="name" value="fruitking"/><br><br>
    <input name="company" value="intohotel"/><br><br>
    <input type="submit" value="submit"/><br>
</form>
</body>
</html>

testpostresult.jsp数据响应页面

<%@ page language="java" pageEncoding="GBK"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
</head>
<body>
    This is my JSP page. <br>
    name:<%=request.getParameter("name")%><br>
    company:<%=request.getParameter("company")%><br>
</body>
</html>

如果用socket如何建立post提交，get提交呢？如果又获得这个http响应呢？

post提交模拟

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.net.URLEncoder;

public class TestSocketPost {

    public static void main(String[] args) {
        BufferedWriter httpPostWriter = null;
        BufferedReader httpResponse = null;
        try {
            // form域的数据.form域的数据必须以链接形式发送
            StringBuffer formDataItems = new StringBuffer();
            formDataItems.append(URLEncoder.encode("name", "GBK"));
            formDataItems.append("=");
            formDataItems.append(URLEncoder.encode("fruitking", "GBK"));
            formDataItems.append("&");
            formDataItems.append(URLEncoder.encode("company", "GBK"));
            formDataItems.append("=");
            formDataItems.append(URLEncoder.encode("intohotel", "GBK"));
            String hostname = "localhost";// 主机，可以是域名，也可以是ip地址
            int port = 8080;// 端口
            InetAddress addr = InetAddress.getByName(hostname);
            // 建立连接
            Socket socket = new Socket(addr, port);
            // 创建数据提交数据流
            httpPostWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "GBK"));
            // 相对主机的请求地址
            String httpSubmitPath = "/icbcnet/testpostresult.jsp";
            // 发送数据头
            httpPostWriter.write("POST " + httpSubmitPath + " HTTP/1.0\r\n");
            httpPostWriter.write("Host: socket方式的post提交测试\r\n");
            httpPostWriter.write("Content-Length: " + formDataItems.length() + "\r\n");
            httpPostWriter.write("Content-Type: application/x-www-form-urlencoded\r\n");
            httpPostWriter.write("\r\n"); // 以空行作为分割
            // 发送数据
            httpPostWriter.write(formDataItems.toString());
            httpPostWriter.flush();
            // 创建web服务器响应的数据流
            httpResponse = new BufferedReader(new InputStreamReader(socket.getInputStream(), "GBK"));
            String lineStr = "";
            while ((lineStr = httpResponse.readLine()) != null) {
                System.out.println(lineStr);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (httpPostWriter != null) {
                    httpPostWriter.close();
                }
                if (httpResponse != null) {
                    httpResponse.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

            httpResponse = new BufferedReader(new InputStreamReader(socket.getInputStream(), "GBK"));
            // 读取每一行的数据.注意大部分端口操作都需要交互数据。
            String lineStr = "";
