Request.Forward 的诀窍在于它为您提供了一个干净的、新的请求来执行您想要的操作。因此,您没有来自当前请求的残留物,例如,依赖 $_SERVER['REQUEST_URI'] 的 java eq 的脚本没有问题。
您可以直接放入一个 CURL 类并编写一个简单的函数来执行此操作:
<?php
/**
* CURLHandler handles simple HTTP GETs and POSTs via Curl
*
* @author SchizoDuckie
* @version 1.0
* @access public
*/
class CURLHandler
{
/**
* CURLHandler::Get()
*
* Executes a standard GET request via Curl.
* Static function, so that you can use: CurlHandler::Get('http://www.google.com');
*
* @param string $url url to get
* @return string HTML output
*/
public static function Get($url)
{
return self::doRequest('GET', $url);
}
/**
* CURLHandler::Post()
*
* Executes a standard POST request via Curl.
* Static function, so you can use CurlHandler::Post('http://www.google.com', array('q'=>'belfabriek'));
* If you want to send a File via post (to e.g. PHP's $_FILES), prefix the value of an item with an @ !
* @param string $url url to post data to
* @param Array $vars Array with key=>value pairs to post.
* @return string HTML output
*/
public static function Post($url, $vars, $auth = false)
{
return self::doRequest('POST', $url, $vars, $auth);
}
/**
* CURLHandler::doRequest()
* This is what actually does the request
* <pre>
* - Create Curl handle with curl_init
* - Set options like CURLOPT_URL, CURLOPT_RETURNTRANSFER and CURLOPT_HEADER
* - Set eventual optional options (like CURLOPT_POST and CURLOPT_POSTFIELDS)
* - Call curl_exec on the interface
* - Close the connection
* - Return the result or throw an exception.
* </pre>
* @param mixed $method Request Method (Get/ Post)
* @param mixed $url URI to get or post to
* @param mixed $vars Array of variables (only mandatory in POST requests)
* @return string HTML output
*/
public static function doRequest($method, $url, $vars=array(), $auth = false)
{
$curlInterface = curl_init();
curl_setopt_array ($curlInterface, array(
CURLOPT_URL => $url,
CURLOPT_CONNECTTIMEOUT => 2,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_FOLLOWLOCATION =>1,
CURLOPT_HEADER => 0));
if (strtoupper($method) == 'POST')
{
curl_setopt_array($curlInterface, array(
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => http_build_query($vars))
);
}
if($auth !== false)
{
curl_setopt($curlInterface, CURLOPT_USERPWD, $auth['username'] . ":" . $auth['password']);
}
$result = curl_exec ($curlInterface);
curl_close ($curlInterface);
if($result === NULL)
{
throw new Exception('Curl Request Error: '.curl_errno($curlInterface) . " - " . curl_error($curlInterface));
}
else
{
return($result);
}
}
}
只需将其转储到 class.CURLHandler.php 中,您就可以这样做:
当然,使用 $_REQUEST 并不是很安全(你应该检查 $_SERVER['REQUEST_METHOD']),但你明白了。
<?php
include('class.CURLHandler.php');
die CURLHandler::doRequest($_SERVER['REQUEST_METHOD'], 'http://server/myaction', $_REQUEST);
?>
当然,CURL 并没有安装在任何地方,但是我们有本地的 PHP curl 模拟器。
此外,这为您提供了比 Request.Forward 更大的灵活性,因为您还可以捕获和后处理输出。
