喔,突然想到,php如何发送http请求,好吧,好蠢啊
因为一直感觉php更像是专门的server
不像是py和node那样,很中

然后转载一波来自网络的内容,这个被转了很多次,我也不知道来源哪里了

神tm六中方法

方法1: 用file_get_contents 以get方式获取内容:

<?php
$url='http://www.jb51.net/';
$html = file_get_contents($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://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

<?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\r\n";
$request.="\r\n";
fwrite($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;
}
?>

我绝对不会用这种超级长的

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/1.1\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

<?php
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, 'http://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;
?>

恕我直言,,,还是file_get_contents比较靠谱
还有你们转载的时候就没有发现,,,,\n\r都丢了\\
改掉好多,懒得改了,应该都是\r\n吧后边的,,蒸米都是只有\n,感觉然后还要改

然后想

node里有request包 => https://github.com/request/request
py里有requests库 => https://github.com/kennethreitz/requests

然后上gayhub上搜了一下,诶?php也有一个
https://github.com/rmccue/Requests

然后看下
好了.再看,再催我就要亲亲抱抱举高高了
