cURL是一个可以在命令行下发起http请求的工具,phpl有调用ibcurl的适配器(adapter),所以在php里可以很方便的使用这个工具。
在使用cURL的过程中是否觉得难以使用,选项太多,没有封装,使用不够方便?
为了方便使用,我对php的cURL进行了二次封装,基于组合模式,使用灵活,能满足多数应用场景,经过我长期的实践。
- 支持 ssl/proxy
- 支持 cookie,会记录所有请求的cookie并带上(如需获得cookie的值,需要自己解析)
- 支持常见请求方法get/post/put/delete 等等RESTFul所需要的方法
- 支持文件上传
- 支持返回http报文和报头
- 支持带cookie的follow location(如果使用curl_setopt($this->_ch, CURLOPT_FOLLOWLOCATION, true);cookie并不会自动带上)
- 解决cURL请求lighttpd会产生417 Expectation Failed错误的问题
实际上Curl_Manager并没有开发到心目中理想的样子,但并不妨碍使用,仅供各位参考:)
测试例子:
- <?php
- require_once(“Curl_Manager.php”);
- $manager = new Curl_Manager();
- $manager->set_action(‘gg’, ‘http://www.google.com/’, ‘http://willko.iteye.com/’);//设置动作,(动作名称, 动作对应url,来源referer)
- $manager->open()->get(‘gg’); //打开一个请求,进行get操作
- echo $manager->body(); // 获得报文
- echo $manager->header(); // 获得报头(需要自己解析)
- //发起ssl请求
- $manager->set_action(‘taobao’, ‘https://login.taobao.com/member/login.jhtml?f=top&redirectURL=http://www.taobao.com/’, ‘http://willko.iteye.com/’);
- $manager->ssl()->get(‘taobao’); //使用ssl方法,让当前这个请求支持ssl请求
- echo $manager->body();
- echo $manager->header();
支持cookie:
带参数请求,get/post/put/delete等等使用方式一样
- $manager->post(‘action’, array(‘k’ => ‘v’, ‘a’ => ‘b’));
- $manager->post(‘action’, ‘k=v&a=b’);
- $manager->post(‘action’, array(‘k’ => ‘v’, ‘@a’ => ‘/home/www/avatar.gif’)); //上传,需要使用绝对路径,参数名称加”@”。
