This article mainly introduces php curl to send fake requests. Now I share it with you and give you a reference. Let’s follow the editor to take a look

    public function curlHtml(){
        //防止超时
        set_time_limit(0);        //要请求的网站的相关参数
        $url = "http://www.w3school.com.cn";        /*$data = array(
            'id'=>1
        );*/
        //初始化一个cURL会话
        $ch = curl_init();        //----------------------------------------

        //伪造来源地址，如果不设置，论坛服务器有可能有验证不允许回复 
        curl_setopt($ch,CURLOPT_REFERER,"http://www.w3school.com.cn");        //能保存cookie
        curl_setopt($ch,CURLOPT_COOKIESESSION,true);  
         //伪造用户浏览器
        curl_setopt($ch,CURLOPT_USERAGENT,"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36");        //伪造请求IP,可以为要请求的网站ip
        curl_setopt($ch, CURLOPT_PROXY, 'https://120.55.40.41:80');      
        //CURLOPT_RETURNTRANSFER 为true，它就将使用PHP curl获取页面内容或提交数据，作为变量储存，而不是直接输出。
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    

        //------------------------------------------

        //使用post方式请求
        /*curl_setopt($ch, CURLOPT_POST, 1);
        //用来支持cookie
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);*/

        //--------------------------------------------

        //设置要请求的url
        curl_setopt($ch, CURLOPT_URL,$url);        //执行请求并获取放回数据  
        $res = curl_exec($ch);        return $res;


    }
