PHP curl函数的使用示例 模拟curl请求
PHP curl函数是可以模仿用户进行访问页面了,下面来给各位介绍一下工作中常用的到的PHP curl函数示例.
PHP有着很好的curl机制,但是用起来总是不那么的令人满意,因为它需要好几步的操作和,好多难记的参数,这里我将php的curl封装了一下,使它不那么的复杂,代码如下:
- <?php
- /**
- * php模拟curl请求
- *
- * @param string $url 请求的url
- * @param string $method 请求的方法, 默认POST
- * @param array $data 请求传递的数据
- * @param array $header 请求设置的头信息
- * @param int $head 是否打印头信息
- * @param int $body 是否打印body信息
- * @param int $timeout 设置超时时间
- *
- * @return array
- */
- function curl($url,$method="POST",$data=array(),$header=array(),$head=0,$body=0,$timeout = 30)
- {
- $ch = curl_init();
- curl_setopt($ch, CURLOPT_URL, $url);
- if (strpos($url, "https") !== false ) {
- curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
- curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
- if (isset($_SERVER['HTTP_USER_AGENT'])) {
- curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
- }
- }
- if (!emptyempty($header)) {
- curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
- }
- switch ($method) {
- case 'POST':
- curl_setopt($ch, CURLOPT_POST, 1);
- curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
- break; //开源软件:phpfensi.com
- case 'GET':
- break;
- case 'PUT':
- curl_setopt($ch, CURLOPT_PUT, 1);
- curl_setopt($ch, CURLOPT_INFILE, '');
- curl_setopt($ch, CURLOPT_INFILESIZE, 10);
- break;
- case 'DELETE':
- curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
- break;
- default:
- break;
- }
- curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
- curl_setopt($ch, CURLOPT_HEADER, $head);
- curl_setopt($ch, CURLOPT_NOBODY, $body);
- curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
- $rtn = curl_exec($ch); //获得返回
- if (curl_errno($ch)) {
- echo 'Errno'.curl_error($ch);//捕抓异常
- }
- curl_close($ch);
- return $rtn;
- }
- ?>
