php發送get、post請求的幾種方法,getpost

編輯:關於PHP編程

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方式獲取內容

1 <?php  
2 $url='http://www.domain.com/';  
3 $html = file_get_contents($url);  
4 echo $html;  
5 ?>  

 

方法2: 用fopen打開url, 以get方式獲取內容

1 <?php  
2 $fp = fopen($url, 'r');  
3 //返回請求流信息(數組:請求狀態,阻塞,返回值是否為空,返回值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方式獲取url

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

 

 1 //生成url-encode後的請求字符串,將數組轉換為字符串  
 2 $data = http_build_query($data);  
 3 $opts = array (  
 4 <span>array (  
 5 <span> 6 <span> 7 <span>strlen($data) . "\r\n",  
 8 <span>$data  
 9 <span>)  
10 ); 

 

1 //生成請求的句柄文件  
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函數打開url,以get方式獲取完整的數據,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 $result;  
22 }  
23 }  
24 //獲取url的html部分,去掉header  
25 function GetUrlHTML($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函數打開url,以POST方式獲取完整的數據,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是否已經打開了curl擴展

 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 ?>
