curl_init的用法，用curl_init请求一个网址，并带参数，返回josn

    public function getUrl($param){
        // 初始化cURL
        $curl = curl_init();
        $url = 'https://www.mabangni.com/send/index.html';
        // 设置URL和其他选项
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query(array('url' =>$param)));
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        // 执行cURL请求
        $response = curl_exec($curl);
        // 将JSON数据转换为数组
        $array = json_decode($response,true);
        // 关闭CURL会话
        curl_close($curl);
        return $array;
    }
