创建 php 代理时出现问题
我无法让它工作：
<?php
$url = 'http://someServer.com/save.asp?';
$count = 0;
foreach($_POST as $key=>$value)
{
if( $count != 0 ) $url .= "&";
$url .= urlencode($key).'='.urlencode($value);
$count++;
}
?>
<html>
<head>
<meta http-equiv="refresh" content="0;url=<?php echo $url;?>">
</head>
<body>
</body>
</html>
如果我复制最终 $url 字符串的输出并将其直接粘贴到浏览器中，它就可以正常工作。
所以看起来 $url 构建正确，但重定向存在一些问题。

我试图让它工作：
<?php
$str = '';
$count = 0;
foreach($_POST as $key=>$value)
{
if( $count != 0 ) $str .= "&";
//$url .= urlencode($key).'='.urlencode($value);
$str .= $key.'='.$value;
$count++;
}
$url = 'http://someDomain.com/acript.asp?'.$str;
$agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
var_dump($result);
?>
我得到：错误的请求
I can't get this to work:
<?php
$url = 'http://someServer.com/save.asp?';
$count = 0;
foreach($_POST as $key=>$value)
{
if( $count != 0 ) $url .= "&";
$url .= urlencode($key).'='.urlencode($value);
$count++;
}
?>
<html>
<head>
<meta http-equiv="refresh" content="0;url=<?php echo $url;?>">
</head>
<body>
</body>
</html>
If I copy the output of the final $url string and paste it in directly in the browser, it works fine.
So it looks like the $url gets built correctly, but there is some problem with the redirection.

如果您希望此功能正常工作，而不依赖浏览器请求页面，请删除所有 HTML 并
添加：
print file_get_contents($url);在末尾 。如果这对您不起作用（并且可能由于多种原因而不起作用），您将不得不使用 - http://php.net/manual/en/book.curl.php。
另外，要构建正确的 url，您不必自己迭代 $_POST，请使用：
http://php.net/manual/en/function.http-build -query.php
PS
无论您想做什么，这可能都是错误的解决方案。
If you want this to work, without relying on the browser to request the page, remove all the HTML and add:
print file_get_contents($url);at the end. if this doesn't work for you (and it may not work for sevral reasons) you will have to use - http://php.net/manual/en/book.curl.php.
Also to build the right url, you don't have to iterate over $_POST yourself, use:
http://php.net/manual/en/function.http-build-query.php
PS
what ever you are trying to do, this is probably the wrong solution.
啊，你的 cURL 太复杂了，它使用 cookie 和标头来指示请求需要一个图像。
只需尝试这个：
如果这仍然不起作用，只需使用 firebug 来查看浏览器发送的标头是什么并添加它们，如下所示：
Ah, your cURL is overly complex, it uses cookies and headers that indicate the request is expecting a an image.
simply try this instead:
if this still doesn't work, just use firebug to see what are the headers you browser is sending and add them, like this:
