CURL这里就不说明了。以下是简单案例
一、POST
//初始化 $curl = curl_init(); //设置抓取的url curl_setopt($curl, CURLOPT_URL, 'http://www.baidu.com'); //设置头文件的信息作为数据流输出 curl_setopt($curl, CURLOPT_HEADER, 1); //设置获取的信息以文件流的形式返回,而不是直接输出。 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //设置post方式提交 curl_setopt($curl, CURLOPT_POST, 1); //设置post数据 $post_data = array( "username" => "coder", "password" => "12345" ); curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data); //执行命令 $data = curl_exec($curl); //关闭URL请求 curl_close($curl); //显示获得的数据 print_r($data);
POST private function _set_headers($user_agent , $client_ip ) { $this->headers = [ 'Content-Type: application/json;charset=UTF-8', 'Authorization: '. self::APP_KEY.':'.$this->sign, 'Date: ' .$this->gmt_date, 'Content-Length: ' .$this->content_len, 'X-FORWARDED-FOR:'. $client_ip, 'CLIENT-IP:'. $client_ip, 'User-Agent:'.$user_agent ]; } private function http_post_json($url, $jsonStr) { $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonStr); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $this->headers); //curl_setopt($ch,CURLOPT_PROXY,'118.0.0.1:8888'); $response = curl_exec($ch); $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE); curl_close($ch); return ['code' => $httpCode, 'msg' => $response]; }
二、GET
//初始化 $curl = curl_init(); //设置抓取的url curl_setopt($curl, CURLOPT_URL, 'http://www.baidu.com'); //设置头文件的信息作为数据流输出 curl_setopt($curl, CURLOPT_HEADER, 1); //设置获取的信息以文件流的形式返回,而不是直接输出。 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); //执行命令 $data = curl_exec($curl); //关闭URL请求 curl_close($curl); //显示获得的数据 print_r($data);
GET //get获取合力token private function http_get_token() { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, self::GET_ACCESS_TOKEN_URL); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $data = curl_exec($ch); var_dump($data);die; $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE); curl_close($ch); return ['code' => $httpCode, 'msg' => CJSON::decode($data, true)]; }
