[PHP] CURL获取cookie，模拟登录获取数据

  • Post author:

需求：通过CURL先登录，然后获取登录后的cookie，在请求数据接口的时候带上这个cookie即可！


直接贴代码：
 

 1 <?php
 2 
 3 class CurlLoginDemo
 4 {
 5     public $config = [
 6         //登录接口和参数
 7         'login_url' => 'http://localhost/login',
 8         'login_post_data' => [
 9             'username' => 'aaa',
10             'password' => 'aaa',
11         ],
12         
13         //数据接口
14         'list_url' => 'http://localhost/list',
15         'list_post_data' => [
16             'page' => 1,
17             'rows' => 30,
18         ],
19      ];
20     public $cookie = '';
21 
22     //登录接口，获取cookie
23     public function login()
24     {
25         $re = $this->post_curl($this->config['login_url'], $this->config['login_post_data'], 1);
26         
27         // 解析HTTP数据流
28         list($header, $body) = explode("\r\n\r\n", $re);
29         // 解析COOKIE
30         preg_match("/set\-cookie:([^\r\n]*)/i", $header, $matches);
31         //请求的时候headers 带上cookie就可以了
32         $cookie = explode(';', $matches[1])[0];
33 
34         $this->cookie = trim($cookie);
35     }
