php發送get、post請求的幾種方法，getpost

轉自：http://blog.csdn.net/haha00217/article/details/7969504

方法1: 用file_get_contents 以get方式擷取內容

1 php  2 $url='http://www.domain.com/';  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 php  2 $fp = fopen($url, 'r');  3 //返回請求流資訊（數組：請求狀態，阻塞，傳回值是否為空白，傳回值http頭等） 

1 stream_get_meta_data($fp);  

1 while(!feof($fp)) {  2 $result .= fgets($fp, 1024);  3 }  4 echo "url body: $result";  5 fclose($fp);  6 ?>  7  

方法3：用file_get_contents函數,以post方式擷取url

1 php  2 $data = array ('foo' => 'bar');  

 1 //產生url-encode後的請求字串，將數群組轉換為字串   2 $data = http_build_query($data);   3 $opts = array (   4 array (   5  6  7 strlen($data) . "\r\n",   8 $data   9 )  10 ); 

1 //產生請求的控制代碼檔案  2 $context = stream_context_create($opts);  3 $html = file_get_contents('http://localhost/e/admin/test.html', false, $context);  4 echo $html;  5 ?>  

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/1.1\r\n";  12 $request .= "Host: $url[host]\r\n";  13 $request .= "Connection: Close\r\n";  14 if($cookie) $request.="Cookie:   $cookie\n";  15 $request.="\r\n";  16 fwrite($fp,$request);  17 while()) {  18 $result .= @fgets($fp, 1024);  19 }  20 fclose($fp);  21 return $result;  22 }  23 }  24 //擷取url的html部分，去掉header  25 function GetUrlHTML($url,$cookie=false)  26 {  27 $rowdata = get_url($url,$cookie);  28 if($rowdata)  29 {  30 $body= stristr($rowdata,"\r\n\r\n");  31 $body=substr($body,4,strlen($body));  32 return $body;  33 }  34     return false;  35 }  36 ?>  

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     // parsing the given URL   5 $URL_Info=parse_url($URL);   6     // Building referrer   7 if($referrer=="") // if not given use this script as referrer   8 $referrer="111";   9     // making string from $data  10 foreach($data as $key=>$value)  11 $values[]="$key=".urlencode($value);  12 $data_string=implode("&",$values);  13     // Find out which port is needed - if not given use standard (=80)  14 if(!isset($URL_Info["port"]))  15 $URL_Info["port"]=80;  16     // building POST-request:  17 $request.="POST ".$URL_Info["path"]." HTTP/1.1\n";  18 $request.="Host: ".$URL_Info["host"]."\n";  19 $request.="Referer: $referer\n";  20 $request.="Content-type: application/x-www-form-urlencoded\n";  21 $request.="Content-length: ".strlen($data_string)."\n";  22 $request.="Connection: close\n";  23     $request.="Cookie:   $cookie\n";  24     $request.="\n";  25 $request.=$data_string."\n";  26     $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);  27 fputs($fp, $request);  28 while(!feof($fp)) {  29 $result .= fgets($fp, 1024);  30 }  31 fclose($fp);  32     return $result;  33 }  34 ?>  

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.domain.com/');   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 echo $file_contents;  10 ?>
