php模拟get、post發送請求的6種方法

方法1: 用file_get_contents 以get方式擷取内容：

<?php
$url='//www.jb51.net/';
$html = file_get_contents($url);
echo $html;
?>
           

 方法2：用file_get_contents函數,以post方式擷取url

<?php
$data = array (‘foo' => ‘bar');
$data = http_build_query($data);
 
$opts = array (
‘http' => array (
‘method' => ‘POST',
‘header'=> “Content-type: application/x-www-form-urlencodedrn” .
“Content-Length: ” . strlen($data) . “rn”,
‘content' => $data
)
);
 
$context = stream_context_create($opts);
$html = file_get_contents(‘http://localhost/e/admin/test.html', false, $context);
 
echo $html;
?>
           

方法3: 用fopen打開url, 以get方式擷取内容 

<?php
$fp = fopen($url, ‘r');
stream_get_meta_data($fp);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
echo “url body: $result”;
fclose($fp);
?>
           

方法4:使用curl庫，使用curl庫之前，可能需要檢視一下php.ini是否已經打開了curl擴充 

<?php
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, ‘//www.jb51.net/');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
 
echo $file_contents;
?>
           

方法5：用fsockopen函數打開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 

<?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/1.1rn”;
        $request .= “Host: $url[host]rn”;
        $request .= “Connection: Closern”;
        if($cookie) $request.=”Cookie:  $cookien”;
        $request.=”rn”;
        fwrite($fp,$request);
        while([email protected]($fp)) {
        $result .= @fgets($fp, 1024);
    }
    fclose($fp);
    return $result;
    }
}

//擷取url的html部分，去掉header
function GetUrlHTML($url,$cookie=false)
{
    $rowdata = get_url($url,$cookie);
    if($rowdata)
    {
        $body= stristr($rowdata,”rnrn”);
        $body=substr($body,4,strlen($body));
        return $body;
    }
    return false;
}
?>
           

方法6：用fsockopen函數打開url，以POST方式擷取完整的資料，包括header和body 

<?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/1.1n”;
    $request.=”Host: “.$URL_Info["host"].”n”;
    $request.=”Referer: $referern”;
    $request.=”Content-type: application/x-www-form-urlencodedn”;
    $request.=”Content-length: “.strlen($data_string).”n”;
    $request.=”Connection: closen”;
 
    $request.=”Cookie:  $cookien”;
 
    $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;
}
 
?>
