1.需求

了解curl的基本get和post用法

2.例子

     timeout = $timeout;        return $this;    }    public function get($url)    {        $ch = curl_init();        curl_setopt($ch, CURLOPT_URL, $url);        curl_setopt($ch, CURLOPT_HEADER, 0);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($ch, CURLOPT_TIMEOUT, $this->timeout);        $result = curl_exec($ch);        curl_close($ch);        return $result;    }    public function post($url,$data)    {        $ch = curl_init();        curl_setopt($ch, CURLOPT_URL, $url);        curl_setopt($ch, CURLOPT_HEADER, 0);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($ch, CURLOPT_TIMEOUT, $this->timeout);        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));        curl_setopt($ch, CURLOPT_POST,true);        $content = curl_exec($ch);        curl_close($ch);        return $content;    }}$obj=new Curl();$arr=array('a'=>1,'b'=>2);$post =$obj->post('http://www.baidu.com',$arr);$get =$obj->get('http://www.baidu.com');

3.总结

这里是最基础的部分，最重要的就是参数的配置问题
