PHP uses curl to obtain verification code (send cookie for secondary capture)_PHP tutorial

I think you may not know the powerful function of curl in php. Now I will introduce an example of using curl to obtain verification codes at work and create cookies.

代码如下

复制代码

$CookieFile=tempnam("./tmep","beast"); if(isset($_GET["img"])){ $url = 'http://www.bKjia.c0m/phper/php.htm';//验证码code $ch = curl_init($url); curl_setopt($ch,CURLOPT_COOKIEJAR, $CookieFile);//把返回来的cookie信息保存在文件中 curl_exec($ch); curl_close($ch); exit(); } if(isset($_POST['d'])){ $b=$_POST[d];//验证码 $p="waybillNo=1721269381&inputcode=".$b; $ch = curl_init(); // 2. 设置选项，包括URL curl_setopt($ch,CURLOPT_URL, "http://www.bKjia.c0m"); curl_setopt($ch,CURLOPT_COOKIEJAR, $CookieFile); curl_setopt($ch,CURLOPT_COOKIEFILE, $CookieFile);//同时发送Cookie curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch,CURLOPT_POST, 1); curl_setopt($ch,CURLOPT_POSTFIELDS, $p);//提交查询信息 $s = curl_exec($ch); curl_close($ch); $ch = curl_init(); curl_setopt($ch,CURLOPT_URL, http://www.bKjia.c0m); curl_setopt($ch,CURLOPT_COOKIEFILE, $CookieFile);//同时发送Cookie curl_setopt($ch,CURLOPT_COOKIEJAR, $CookieFile); curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch,CURLOPT_POST, 1); curl_setopt($ch,CURLOPT_POSTFIELDS, $p);//提交查询信息 $bs = curl_exec($ch); echo $bs;//输出结果 curl_close($ch); }else{ ?> ?>
