php發送get、post請求的6種方法程式碼範例

標籤：

本文主要展示了php發送get、post請求的6種方法的程式碼範例,分別為使用file_get_contents 、fopen、fsockopen、curl來發送GET和POST請求，代碼如下： 方法1: 用file_get_contents 以get方式擷取內容：

1 <?php2     $url=‘http://www.jb51.net/‘;3     $html = file_get_contents($url);4     echo $html;5 ?>

方法2: 用fopen開啟url, 以get方式擷取內容：

1 <?php2     $fp = fopen($url, ‘r‘);3     stream_get_meta_data($fp);4     while(!feof($fp)) {5         $result .= fgets($fp, 1024);6     }7     echo “url body: $result”;8     fclose($fp);9 ?>

方法3：用file_get_contents函數,以post方式擷取url

 1 <?php 2     $data = array (‘foo‘ => ‘bar‘); 3     $data = http_build_query($data); 4   5     $opts = array ( 6         ‘http‘ => array ( 7             ‘method‘ => ‘POST‘, 8             ‘header‘=> “Content-type: application/x-www-form-urlencodedrn” . “Content-Length: ” . strlen($data) . “rn”,10             ‘content‘ => $data11         )12     );13  14     $context = stream_context_create($opts);15     $html = file_get_contents(‘http://localhost/e/admin/test.html‘, false, $context);16  17     echo $html;18 ?>

方法4：用fsockopen函數開啟url，以get方式擷取完整的資料，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 選項開啟

 1 <?php 2     function get_url ($url,$cookie=false) 3     { 4         $url = parse_url($url); 5         $query = $url[path].”?”.$url[query]; 6         echo “Query:”.$query; 7         $fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30); 8         if (!$fp) { 9             return false;10         } else {11             $request = “GET $query HTTP/1.1rn”;12             $request .= “Host: $url[host]rn”;13             $request .= “Connection: Closern”;14             if($cookie) $request.=”Cookie:  $cookien”;15             $request.=”rn”;16             fwrite($fp,$request);17             while([email protected]feof($fp)) {18                 $result .= @fgets($fp, 1024);19             }20             fclose($fp);21             return $result;22         }23     }24     //擷取url的html部分，去掉header25     function GetUrlHTML($url,$cookie=false)26     {27         $rowdata = get_url($url,$cookie);28         if($rowdata)29         {30             $body= stristr($rowdata,”rnrn”);31             $body=substr($body,4,strlen($body));32             return $body;33         }34  35         return false;36     }37 ?>

方法5：用fsockopen函數開啟url，以POST方式擷取完整的資料，包括header和body

 1 <?php 2     function HTTP_Post($URL,$data,$cookie, $referrer=”") 3     { 4   5         // parsing the given URL 6         $URL_Info=parse_url($URL); 7   8         // Building referrer 9         if($referrer==”") // if not given use this script as referrer10             $referrer=”111″;11  12         // making string from $data13         foreach($data as $key=>$value)14             $values[]=”$key=”.urlencode($value);15         $data_string=implode(“&”,$values);16  17         // Find out which port is needed – if not given use standard (=80)18         if(!isset($URL_Info["port"]))19             $URL_Info["port"]=80;20  21         // building POST-request:22         $request.=”POST “.$URL_Info["path"].” HTTP/1.1n”;23         $request.=”Host: “.$URL_Info["host"].”n”;24         $request.=”Referer: $referern”;25         $request.=”Content-type: application/x-www-form-urlencodedn”;26         $request.=”Content-length: “.strlen($data_string).”n”;27         $request.=”Connection: closen”;28  29         $request.=”Cookie:  $cookien”;30  31         $request.=”n”;32         $request.=$data_string.”n”;33  34         $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);35         fputs($fp, $request);36         while(!feof($fp)) {37              $result .= fgets($fp, 1024);38         }39         fclose($fp);40  41         return $result;42     }43 ?>

方法6:使用curl庫，使用curl庫之前，可能需要查看一下php.ini是否已經開啟了curl擴充

 1 <?php 2     $ch = curl_init(); 3     $timeout = 5; 4     curl_setopt ($ch, CURLOPT_URL, ‘http://www.jb51.net/‘); 5     curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 6     curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 7     $file_contents = curl_exec($ch); 8     curl_close($ch); 9  10     echo $file_contents;11 ?>
