php CURL does not use file access COOKIE example_PHP tutorial

This article will introduce you to an example of php CURL not using COOKIE for file access. I hope this instruction will be helpful to all students.

CURL is a very practical PHP extension. It is often necessary to access COOKIE information when simulating user login. Using COOKIEJAR and COOKIEFILE will generate two or more I/O operations. Needless to say, performance efficiency is discussed in Chapter 1. Third-party cloud application platforms (BAE SAE, etc.) sometimes need to operate STORAGE to access COOKIE, which is troublesome. Today I will introduce a CURL method to access COOKIE without using files:

COOKIEJAR/COOKIEFILE method:

$url = 'www.bKjia.c0m'; //url address $post = "id=user&pwd=123456"; //POST data

The code is as follows

代码如下

复制代码

/*-----保存COOKIE-----*/ $url = 'www.bKjia.c0m'; //url地址 $post = "id=user&pwd=123456"; //POST数据 $cookie = tempnam('./','cookie'); //cookie临时文件 $ch = curl_init($url); //初始化 curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //返回获取的输出文本流 curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //发送POST数据 curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie); //保存获得的cookie curl_exec($ch); //执行curl curl_close($ch); //关闭curl /*-----使用COOKIE-----*/ curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie);

Copy code

代码如下

复制代码

/*-----保存COOKIE-----*/ $url = 'www.bKjia.c0m'; //url地址 $post = "id=user&pwd=123456"; //POST数据 $cookie = tempnam('./','cookie'); //cookie临时文件 $ch = curl_init($url); //初始化 curl_setopt($ch,CURLOPT_HEADER,1); //将头文件的信息作为数据流输出 curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //返回获取的输出文本流 curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //发送POST数据 $content = curl_exec($ch); //执行curl并赋值给$content preg_match('/Set-Cookie:(.*);/iU',$content,$str); //正则匹配 $cookie = $str[1]; //获得COOKIE（SESSIONID） curl_close($ch); //关闭curl /*-----使用COOKIE-----*/ curl_setopt($ch,CURLOPT_COOKIE,$cookie); /*-----保存COOKIE-----*/ $url = 'www.bKjia.c0m'; //url地址 $post = "id=user&pwd=123456"; //POST数据 $cookie = tempnam('./','cookie'); //cookie临时文件 $ch = curl_init($url); //初始化 curl_setopt($ch,CURLOPT_HEADER,1); //将头文件的信息作为数据流输出 curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //返回获取的输出文本流 curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //发送POST数据 $content = curl_exec($ch); //执行curl并赋值给$content preg_match('/Set-Cookie:(.*);/iU',$content,$str); //正则匹配 $cookie = $str[1]; //获得COOKIE（SESSIONID） curl_close($ch); //关闭curl /*-----使用COOKIE-----*/ curl_setopt($ch,CURLOPT_COOKIE,$cookie);

/*-----SAVE COOKIE-----*/

$cookie = tempnam('./','cookie'); //cookie temporary file $ch = curl_init($url); //Initialization

curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //Return the obtained output text stream

curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //Send POST data curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie); //Save the obtained cookie curl_exec($ch); //Execute curl curl_close($ch); //Close curl /*-----USE COOKIE-----*/ curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie); New method (no I/O operation):

The code is as follows

/*-----SAVE COOKIE-----*/ $url = 'www.bKjia.c0m'; //url address $post = "id=user&pwd=123456"; //POST data $cookie = tempnam('./','cookie'); //cookie temporary file $ch = curl_init($url); //Initialization curl_setopt($ch,CURLOPT_HEADER,1); //Output the header file information as a data stream curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //Return the obtained output text stream curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //Send POST data $content = curl_exec($ch); //Execute curl and assign value to $content preg_match('/Set-Cookie:(.*);/iU',$content,$str); //Regular matching $cookie = $str[1]; //Get COOKIE (SESSIONID) curl_close($ch); //Close curl /*-----USE COOKIE-----*/ curl_setopt($ch,CURLOPT_COOKIE,$cookie); /*-----SAVE COOKIE-----*/ $url = 'www.bKjia.c0m'; //url address $post = "id=user&pwd=123456"; //POST data $cookie = tempnam('./','cookie'); //cookie temporary file $ch = curl_init($url); //Initialization curl_setopt($ch,CURLOPT_HEADER,1); //Output the header file information as a data stream curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); //Return the obtained output text stream curl_setopt($ch,CURLOPT_POSTFIELDS,$post); //Send POST data $content = curl_exec($ch); //Execute curl and assign value to $content preg_match('/Set-Cookie:(.*);/iU',$content,$str); //Regular matching $cookie = $str[1]; //Get COOKIE (SESSIONID) curl_close($ch); //Close curl /*-----USE COOKIE-----*/ curl_setopt($ch,CURLOPT_COOKIE,$cookie); http://www.bkjia.com/PHPjc/631496.htmlwww.bkjia.comtruehttp: //www.bkjia.com/PHPjc/631496.htmlTechArticleThis article will introduce you to an example of php CURL not using file access COOKIE.
