一、S02E195_01手写服务器httpserver_准备_Socket入门

package com.test.server;import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;
/*** 创建服务器，并启动*/
public class Server {private ServerSocket server;public static void main(String[] args) {Server server = new Server();server.start();}/*** 启动方法*/public void start(){        try {server = new ServerSocket(8888);this.receive();} catch (IOException e) {e.printStackTrace();}}/*** 接收客户端*/private void receive(){try {Socket client =server.accept();StringBuilder sb =new StringBuilder();String msg =null;//接收客户端的请求信息BufferedReader br = new BufferedReader(new InputStreamReader(client.getInputStream()));while((msg=br.readLine()).length()>0){sb.append(msg);sb.append("\r\n");if(null==msg){break;}}//接收客户端的请求信息String requestInfo =sb.toString().trim();       System.out.println(requestInfo);} catch (IOException e) {//e.printStackTrace();}}/*** 停止服务器*/public void stop(){}
}//输出信息：
GET / HTTP/1.1
Host: localhost:8888
Connection: keep-alive
Cache-Control: max-age=0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36
Accept-Encoding: gzip,deflate,sdch
Accept-Language: zh-CN,zh;q=0.8

二、S02E196_01手写服务器httpserver_准备_html

1、get方式提交

<html><head><title>第一个表单</title></head><body><pre>method：请求方式 get/postget：默认方式，数据量小，安全性不高post：量大，安全性相对高action：请求的服务器路径id：编号，前端（用户的浏览器）区分唯一性，js中使用name：名称，后端（服务器）区分唯一性，获取值只要提交数据给后台，必须存在name</pre><form method="get" action="http://localhost:8888/index.html">用户名：<input type="text" name="uname" id="name">密码：<input type="password" name="pwd" id="pass"><input type="submit" value="登录"></form></body>
</html>

用户请求get出去

//输出信息：（第一句包含uname=intputUname&pwd=inputPassword）
GET /index.html?uname=intputUname&pwd=inputPassword HTTP/1.1
Host: localhost:8888
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36
Accept-Encoding: gzip,deflate,sdch
Accept-Language: zh-CN,zh;q=0.8

2、post方式提交
（method=”get” 改为method=”post”）

<html><head><title>第一个表单</title></head><body><pre>method：请求方式 get/postget：默认方式，数据量小，安全性不高post：量大，安全性相对高action：请求的服务器路径id：编号，前端（用户的浏览器）区分唯一性，js中使用name：名称，后端（服务器）区分唯一性，获取值只要提交数据给后台，必须存在name</pre><form method="post" action="http://localhost:8888/index.html">用户名：<input type="text" name="uname" id="name">密码：<input type="password" name="pwd" id="pass"><input type="submit" value="登录"></form></body>
</html>

修改代码输出post方式的请求

package com.test.server;import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
/*** 创建服务器，并启动*/
public class ServerForPost {private ServerSocket server;public static void main(String[] args) {ServerForPost server = new ServerForPost();server.start();}/*** 启动方法*/public void start(){        try {server = new ServerSocket(8888);this.receive();} catch (IOException e) {e.printStackTrace();}}/*** 接收客户端*/private void receive(){try {Socket client =server.accept();StringBuilder sb =new StringBuilder();byte[] date = new byte[20480];int len = client.getInputStream().read(date);//接收客户端的请求信息String requestInfo = new String(date,0,len).trim();     System.out.println(requestInfo);} catch (IOException e) {//e.printStackTrace();}}/*** 停止服务器*/public void stop(){}
}//输出信息：（最后一句包含uname=intputUname&pwd=inputPassword）
POST /index.html HTTP/1.1
Host: localhost:8888
