取消HTTP POST请求服务器端 [英] Cancel an HTTP POST request server side

问题描述

我正在尝试编写用于上传大文件（> 500MB）的脚本。我想在处理上传之前进行一些身份验证，例如：

I am trying to write a script for uploading large files (>500MB). I would like to do some authentication before the upload is processed, eg:

$id = $_GET['key'];
$size = $_GET['size'];
$time = $_GET['time'];
$signature = $_GET['signature'];

$secret = 'asdfgh123456';

if(sha1($id.$size.$time.$secret) != $signature){
echo 'invalid signature';
exit;
}
process upload...

不幸的是php只运行此代码该文件已上载到临时目录，占用宝贵的服务器资源。在上传发生之前有没有办法做到这一点？我用perl / cgi尝试了类似的事情，但同样的事情发生了。

unfortunately php only runs this code after the file has been uploaded to a temp directory, taking up valuable server resources. Is there a way to do this before the upload happens? I have tried similar things with perl/cgi but the same thing happens.

推荐答案

哇，已经有5个答案告诉它怎么可能'完成。 mod_perl to救援，您可以在上传整个请求正文之前拒绝请求。

Wow, already 5 answers telling how it can't be done. mod_perl to the rescue, here you can reject a request before the whole request body is uploaded.
