PHP输入流php://input实例讲解_php技巧
对于php://input介绍,PHP官方手册文档有一段话对它进行了很明确地概述。 “php://input allows you to read raw POST data. It is a less memory intensive alternative to$HTTP_RAW_POST_DATA and does not need any special php.ini directives. php://input is not available with enctype=”multipart/form-data”. 翻译过来,是这样:
总结起来就是,在用$_POST获取不到由APP或者一些接口的回调数据时,就用php://input试试 1、 接受xml数据 //发送xml数据$xml = '<xml>xmldata</xml>';//要发送的xml $url = 'http://localhost/test/getXML.php';//接收XML地址 $header = 'Content-type: text/xml';//定义content-type为xml $ch = curl_init(); //初始化curl curl_setopt($ch, CURLOPT_URL, $url);//设置链接 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//设置是否返回信息 curl_setopt($ch, CURLOPT_HTTPHEADER, $header);//设置HTTP头 curl_setopt($ch, CURLOPT_POST, 1);//设置为POST方式 curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);//POST数据 $response = curl_exec($ch);//接收返回信息 if(curl_errno($ch)){//出错则显示错误信息 print curl_error($ch); } curl_close($ch); //关闭curl链接 echo $response;//显示返回信息 // php用file_get_contents("php://input")或者$HTTP_RAW_POST_DATA可以接收xml数据$xmldata = file_get_contents("php://input"); $data = (array)simplexml_load_string($xmldata); 2、手机上传图片到服务器的小程序 //@file phpinput_post.php $data=file_get_contents('btn.png'); $http_entity_body = $data; $http_entity_type = 'application/x-www-form-urlencoded'; $http_entity_length = strlen($http_entity_body); $host = '127.0.0.1'; $port = 80; $path = '/image.php'; $fp = fsockopen($host, $port, $error_no, $error_desc, 30); if ($fp){ fputs($fp, "POST {$path} HTTP/1.1/r/n"); fputs($fp, "Host: {$host}/r/n"); fputs($fp, "Content-Type: {$http_entity_type}/r/n"); fputs($fp, "Content-Length: {$http_entity_length}/r/n"); fputs($fp, "Connection: close/r/n/r/n"); fputs($fp, $http_entity_body . "/r/n/r/n"); while (!feof($fp)) { $d .= fgets($fp, 4096); } fclose($fp); echo $d; } 接收 /** *Recieve image data **/error_reporting(E_ALL);function get_contents() { $xmlstr= file_get_contents("php://input"); $filename=file_put_contentsxmltime().'.png'; if(($filename,$str)){ echo 'success'; }else{ echo 'failed'; } }get_contents(); 3:获取HTTP请求原文 /** * 获取HTTP请求原文 * @return string */function get_http_raw(){ $raw = ''; // (1) 请求行 $raw .= $_SERVER['REQUEST_METHOD'] . ' ' . $_SERVER['REQUEST_URI'] . ' ' . $_SERVER['SERVER_PROTOCOL'] . "/r/n"; // (2) 请求Headers foreach ($_SERVER as $key => $value) { if (substr($key , 0 , 5) === 'HTTP_') { $key = substr($key , 5); $key = str_replace('_' , '-' , $key); $raw .= $key . ': ' . $value . "/r/n"; } } // (3) 空行 $raw .= "/r/n"; // (4) 请求Body $raw .= file_get_contents('php://input'); return $raw;} 以上就是针对PHP输入流举的三个小栗子,目的在于帮助大家更准确的理解PHP输入流,希望大家有所收获。 |
