表示已成功,但是不完全,我們接着看res.html中的內容
在網頁中有如下內容:表明需要先登錄以後才能操作
服務器怎麼知道咱們沒登陸的?
http一個很重要的特點:無狀態,兩次請求之間沒有關係。
服務器如何記住一個客戶?
建立cookie.php
<?php
header('content-type:text/html;charset=utf8');
setcookie('user','zhangsan');
echo '服務器給你的編號是zhangsan';
?>
建立readcookie.php
<?php
header('content-type:text/html;charset=utf8');
echo '服務器給你的編號是'.$_COOKIE['user'];
?>
利用命令窗口提交請求
增加提交的信息
<?php
require('./http.class.php');

再看wuming1990的用戶是否收到信息
(PS:如果發送不成功,表明COOKIE值不對,cookie的生成與請求頭信息有關,保守做法:把全部請求頭信息加到post請求裏面)
