HTTP协议分析系列（六）------php+socket+cookie请求
以www.verycd.com为例
在火狐浏览器登录wuming88888888账号为发送方
在chrome浏览器登录wuming1990账号为接收方
分析发送方的表单
分析提交页源代码POST的数据
<?php
require("./http.class.php");
$http=new Http("http://home.verycd.com/cp.php?ac=pm&op=send&touid=0&pmid=0");
$msg=array(
"formhash"=>"10fe754a",
"message"=>"你好",
"pmsubmit"=>true,
"pmsubmit_btn"=>"发送",
"refer"=>"http://home.verycd.com/space.php?do=pm&filter=privatepm",
"username"=>"wuming1990"
);
file_put_contents("./res.html",$http->post($msg));
?>打开res.html,分析源代码

调试查看自己发送的是什么内容？
这时候我们可以分析出错误出现在第一行
打印该对象

)修改我们的http类
<pre name="code" class="php"> //http请求类的接口
interface Proto{
//连接url
function conn($url);
//发送get查询
function get();
//发送post查询
function post();
//关闭连接
function close();
}
class Http implements Proto{
const CRLF="

protected $errno=-1;
protected $errstr="";

$this->fh=fsockopen($this->url["host"],$this->url["port"],$this->errno,$this->errstr,3);
}
//构造get请求的数据

$this->request();

//构造post请求的数据
function post($body=array()){

$this->setLine("POST");
//设置content-type
$this->setHeader("Content-type:application/x-www-form-urlencoded");
//设置主体信息，比GET不一样的地方
$this->setBody($body);
//计算content-length
$this->setHeader("Content-length:".strlen($this->body[0]));
$this->request();
return $this->response;
}
//真正请求
function request(){
//把请求行，头信息，实体信息 放在一个数组里，便于拼接
$req=array_merge($this->line,$this->header,array(""),$this->body,array(""));
$req=implode(self::CRLF,$req);

$this->close();//关闭连接

//关闭连接
function close(){

}
}生成如下POST /cp.php?ac=pm&op=send&touid=0&pmid=0 HTTP/1.1Host:home.verycd.comContent-type:application/x-www-form-urlencodedContent-length:185formhash=10fe754a&message=%E4%BD%A0%E5%A5%BD&pmsubmit=1&pmsubmit_btn=%E5%8F%91%E9%80%81&refer=http%3A%2F%2Fhome.verycd.com%2Fspace.php%3Fdo%3Dpm%26filter%3Dprivatepm&username=wuming1990

服务器怎么知道咱们没登陆的？
http一个很重要的特点：无状态，两次请求之间没有关系。
服务器如何记住一个客户？
建立cookie.php
<?php
header("content-type:text/html;charset=utf8");
setcookie("user","zhangsan");
echo "服务器给你的编号是zhangsan";
?>
建立readcookie.php
<?php
header("content-type:text/html;charset=utf8");
echo "服务器给你的编号是".$_COOKIE["user"];
?>
利用命令窗口提交请求
增加提交的信息
<?php
require("./http.class.php");
$http=new Http("http://home.verycd.com/cp.php?ac=pm&op=send&touid=0&pmid=0");
$http->setHeader("cookie:Hm_lvt_c7849bb40e146a37d411700cb7696e46=1417760419; Hm_lpvt_c7849bb40e146a37d411700cb7696e46=1417760610; post_action=repost; sid=7fd8c62c8d000561d658c4e25eccb6f791a8d4b6; member_id=9933070; member_name=wuming88888888; mgroupId=93; pass_hash=263b6d67494b1888f1e7b8cc227ea4bd; rememberme=true; uchome_auth=63a2o4ZG8YsPG1Tv4%2FIYiydpKrQVqgKgxAQgp%2FI5ZxYQIVjc8ad40VEyW2peEmnKYwKQ2qserNpgSOrxwXLKpDomid%2Fq; uchome_loginuser=wuming88888888; CNZZDATA1479=cnzz_eid%3D407399210-1417756656-http%253A%252F%252Fwww.verycd.com%252F%26ntime%3D1417756656; __utma=248211998.394160120.1417760633.1417760633.1417760633.1; __utmb=248211998.8.10.1417760633; __utmc=248211998; __utmz=248211998.1417760633.1.1.utmcsr=verycd.com|utmccn=(referral)|utmcmd=referral|utmcct=/account/profile/base/; __utmt=1; uchome_sendmail=1; uchome_checkpm=1; dcm=1");

file_put_contents("./res.html",$http->post($msg));
echo "ok";
?>再看wuming1990的用户是否收到信息
（PS：如果发送不成功，表明COOKIE值不对，cookie的生成与请求头信息有关，保守做法：把全部请求头信息加到post请求里面）
