php发送get、post请求的几种方法

方法1: 用file_get_contents 以get方式获取内容

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

 

方法2: 用fopen打开url, 以get方式获取内容

  1. <?php  
  2. $fp = fopen($url, ‘r‘);  
  3. //返回请求流信息(数组:请求状态,阻塞,返回值是否为空,返回值http头等)  
<?php
$fp = fopen($url, ‘r‘);
//返回请求流信息(数组:请求状态,阻塞,返回值是否为空,返回值http头等)
  1. stream_get_meta_data($fp);  
stream_get_meta_data($fp);
  1. while(!feof($fp)) {  
  2. $result .= fgets($fp, 1024);  
  3. }  
  4. echo "url body: $result";  
  5. fclose($fp);  
  6. ?>  
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
echo "url body: $result";
fclose($fp);
?>

 

方法3:用file_get_contents函数,以post方式获取url

  1. <?php  
  2. $data = array (‘foo‘ => ‘bar‘);  
<?php
$data = array (‘foo‘ => ‘bar‘);
  1. //生成url-encode后的请求字符串,将数组转换为字符串  
  2. $data = http_build_query($data);  
  3. $opts = array (  
  4. <span style="white-space: pre;">    </span>‘http‘ => array (  
  5. <span style="white-space: pre;">        </span>‘method‘ => ‘POST‘,  
  6. <span style="white-space: pre;">        </span>‘header‘=> "Content-type: application/x-www-form-urlencoded\r\n" .  
  7. <span style="white-space: pre;">        </span>"Content-Length: " . strlen($data) . "\r\n",  
  8. <span style="white-space: pre;">        </span>‘content‘ => $data  
  9. <span style="white-space: pre;">    </span>)  
  10. );  
//生成url-encode后的请求字符串,将数组转换为字符串
$data = http_build_query($data);
$opts = array (
	‘http‘ => array (
		‘method‘ => ‘POST‘,
		‘header‘=> "Content-type: application/x-www-form-urlencoded\r\n" .
		"Content-Length: " . strlen($data) . "\r\n",
		‘content‘ => $data
	)
);
  1. //生成请求的句柄文件  
  2. $context = stream_context_create($opts);  
  3. $html = file_get_contents(‘http://localhost/e/admin/test.html‘, false, $context);  
  4. echo $html;  
  5. ?>  
//生成请求的句柄文件
$context = stream_context_create($opts);
$html = file_get_contents(‘http://localhost/e/admin/test.html‘, false, $context);
echo $html;
?>

 

方法4:用fsockopen函数打开url,以get方式获取完整的数据,包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启

  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 $result;  
  22. }  
  23. }  
  24. //获取url的html部分,去掉header  
  25. function GetUrlHTML($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 $body;  
  33. }  
  34.     return false;  
  35. }  
  36. ?>  
<?php
function get_url ($url,$cookie=false)
{
$url = parse_url($url);
$query = $url[path]."?".$url[query];
echo "Query:".$query;
$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);
if (!$fp) {
return false;
} else {
$request = "GET $query HTTP/1.1\r\n";
$request .= "Host: $url[host]\r\n";
$request .= "Connection: Close\r\n";
if($cookie) $request.="Cookie:   $cookie\n";
$request.="\r\n";
fwrite($fp,$request);
while()) {
$result .= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}
//获取url的html部分,去掉header
function GetUrlHTML($url,$cookie=false)
{
$rowdata = get_url($url,$cookie);
if($rowdata)
{
$body= stristr($rowdata,"\r\n\r\n");
$body=substr($body,4,strlen($body));
return $body;
}
    return false;
}
?>

 

方法5:用fsockopen函数打开url,以POST方式获取完整的数据,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 $result;  
  33. }  
  34. ?>  
<?php
function HTTP_Post($URL,$data,$cookie, $referrer="")
{
    // parsing the given URL
$URL_Info=parse_url($URL);
    // Building referrer
if($referrer=="") // if not given use this script as referrer
$referrer="111";
    // making string from $data
foreach($data as $key=>$value)
$values[]="$key=".urlencode($value);
$data_string=implode("&",$values);
    // Find out which port is needed - if not given use standard (=80)
if(!isset($URL_Info["port"]))
$URL_Info["port"]=80;
    // building POST-request:
$request.="POST ".$URL_Info["path"]." HTTP/1.1\n";
$request.="Host: ".$URL_Info["host"]."\n";
$request.="Referer: $referer\n";
$request.="Content-type: application/x-www-form-urlencoded\n";
$request.="Content-length: ".strlen($data_string)."\n";
$request.="Connection: close\n";
    $request.="Cookie:   $cookie\n";
    $request.="\n";
$request.=$data_string."\n";
    $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
fputs($fp, $request);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
fclose($fp);
    return $result;
}
?>

 

方法6:使用curl库,使用curl库之前,可能需要查看一下php.ini是否已经打开了curl扩展

  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. ?>
