1. http Get

简单的只需要 这四行 就

$ch = curl_init ();curl_setopt ( $ch, CURLOPT_URL, "http://site" );$output = curl_exec($ch);curl_close ( $ch );

复杂的

public static function curlGet($url,$cookiefile,$header=null){        try{            $ch = curl_init ();            curl_setopt ( $ch, CURLOPT_URL, $url );            curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );            //不知道如何看发出去的数据是什么样子的 使用这句话 可通过抓包工具查看到            // 需要抓包工具配合使用            curl_setopt($ch,CURLOPT_PROXY,'192.168.2.221:8889');            if($header){//                 curl_setopt ( $ch, CURLOPT_HEADER, 1 );                curl_setopt($ch, CURLOPT_HTTPHEADER, $header);//                 curl_setopt ( $ch, CURLOPT_COOKIE,$header['Cookie'] );//                 curl_setopt ( $ch, CURLOPT_COOKIESESSION,$header['Cookie'] );            }            else{                curl_setopt ( $ch, CURLOPT_HEADER, 0 );            }                if($cookiefile){                curl_setopt ( $ch, CURLOPT_COOKIEFILE, $cookiefile ); // 读取cookie                curl_setopt ( $ch, CURLOPT_COOKIEJAR, $cookiefile ); // 设置Cookie信息保存在指定的文件中            }                            $output = curl_exec($ch); //          获取curl 信息            $information = curl_getinfo($ch);            curl_close ( $ch );        }catch(\Exception $e){            print_r($e->getMessage());        }        return $output;    }

　　

2. http Post

public static function curlPost($url,$data,$cookiefile=null,$header=null){        try{            $ch = curl_init ();            curl_setopt ( $ch, CURLOPT_URL, $url );                    curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );            curl_setopt ( $ch, CURLOPT_POST, 1 );            curl_setopt($ch,CURLOPT_PROXY,'192.168.2.221:8889');            if($header){                curl_setopt($ch, CURLOPT_HTTPHEADER, $header);            }            else{                curl_setopt ( $ch, CURLOPT_HEADER, 0 );            }            if($cookiefile){
    　　　　　　　　　　curl_setopt ( $ch, CURLOPT_COOKIEFILE, $cookiefile ); // 读取cookie                curl_setopt ( $ch, CURLOPT_COOKIEJAR, $cookiefile ); // 设置Cookie信息保存在指定的文件中            }   　　　　　　//!!!注意data的格式            curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data);            //设置响应超时时间            curl_setopt($ch, CURLOPT_TIMEOUT, 120);                        $output = curl_exec($ch);            if($output === false){                if(curl_errno($ch) == CURLE_OPERATION_TIMEDOUT){                    //处理逻辑                }            }            $information = curl_getinfo($ch);            curl_close ( $ch );        }catch(\Exception $e){            print_r($e->getMessage());        }        return $output;    }
