• php发送get、post请求的6种方法简明总结


    方法1: 用file_get_contents 以get方式获取内容:

    <?php
    $url='http://www.51growup.com/';
    $html = file_get_contents($url);
    echo $html;
    ?>

    方法2: 用fopen打开url, 以get方式获取内容:

    <?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3:用file_get_contents函数,以post方式获取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://www.51growup.com/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

    <?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,$request);
    while(!@feof($fp)) {
    $result .= @fgets($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,"rnrn");
    $body=substr($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

    <?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;
    }
    
    ?>

    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

    <?php
    $ch = curl_init();
    $timeout = 5;
    curl_setopt ($ch, CURLOPT_URL, 'http://www.51growup.com/');
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $file_contents = curl_exec($ch);
    curl_close($ch);
    
    echo $file_contents;
    ?>
