PHP 使用 Fsockopen 发布数据 [英] PHP Post data with Fsockopen

问题描述

我正在尝试使用 fsockopen 发布数据，然后返回结果.这是我当前的代码:

I am attempting to post data using fsockopen, and then returning the result. Here is my current code:

<?php
$data="stuff=hoorah
";
$data=urlencode($data);

$fp = fsockopen("www.website.com", 80, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br />
";
} else {
    $out = "POST /script.php HTTP/1.0
";
    $out .= "Host: www.webste.com
";
    $out .= 'Content-Type: application/x-www-form-urlencoded
';
    $out .= 'Content-Length: ' . strlen($data) . '

';
    $out .= "Connection: Close

";
    fwrite($fp, $out);
    while (!feof($fp)) {
        echo fgets($fp, 128);
    }
    fclose($fp);
}
?> 

应该是回显页面，也是回显页面，但是这里是script.php的脚本

It is supposed to echo the page, and it is echoing the page, but here is the script for script.php

<?php
echo "<br><br>";    
$raw_data = $GLOBALS['HTTP_RAW_POST_DATA'];  
 parse_str( $raw_data, $_POST );

//test 1
var_dump($raw_data);
echo "<br><br>":
//test 2
print_r( $_POST );  
?>

结果是:

HTTP/1.1 200 OK 日期:2010 年 3 月 2 日，星期二22:40:46 GMT 服务器:Apache/2.2.3(CentOS) X-Powered-By: PHP/5.2.6内容长度:31 连接:关闭内容类型:文本/html；字符集=UTF-8string(0) "" 数组 ( )

HTTP/1.1 200 OK Date: Tue, 02 Mar 2010 22:40:46 GMT Server: Apache/2.2.3 (CentOS) X-Powered-By: PHP/5.2.6 Content-Length: 31 Connection: close Content-Type: text/html; charset=UTF-8 string(0) "" Array ( )

我有什么问题?为什么变量不发布其数据?

What do I have wrong? Why isn't the variable posting its data?

推荐答案

您的代码中有许多小错误.这是一个经过测试且有效的片段.

There are many small errors in your code. Here's a snippet which is tested and works.

<?php

$fp = fsockopen('example.com', 80);

$vars = array(
    'hello' => 'world'
);
$content = http_build_query($vars);

fwrite($fp, "POST /reposter.php HTTP/1.1
");
fwrite($fp, "Host: example.com
");
fwrite($fp, "Content-Type: application/x-www-form-urlencoded
");
fwrite($fp, "Content-Length: ".strlen($content)."
");
fwrite($fp, "Connection: close
");
fwrite($fp, "
");

fwrite($fp, $content);

header('Content-type: text/plain');
while (!feof($fp)) {
    echo fgets($fp, 1024);
}

然后在example.com/reposter.php把这个

And then at example.com/reposter.php put this

<?php print_r($_POST);

运行时你应该得到类似的输出

When run you should get output something like

HTTP/1.1 200 OK
Date: Wed, 05 Jan 2011 21:24:07 GMT
Server: Apache
X-Powered-By: PHP/5.2.9
Vary: Host
Content-Type: text/html
Connection: close

1f
Array
(
    [hello] => world
)
0
