发送非阻塞HTTP POST请求 [英] sending a non-blocking HTTP POST request

问题描述

我有两个使用php和python的网站. 当用户向服务器发送请求时，我需要php/python将HTTP POST请求发送至远程服务器.我想立即回复用户，而不必等待远程服务器的响应.

I have a two websites in php and python. When a user sends a request to the server I need php/python to send an HTTP POST request to a remote server. I want to reply to the user immediately without waiting for a response from the remote server.

在向用户发送响应后，是否可以继续运行php/python脚本.在这种情况下，我将首先回复用户，然后才将HTTP POST请求发送到远程服务器.

Is it possible to continue running a php/python script after sending a response to the user. In that case I'll first reply to the user and only then send the HTTP POST request to the remote server.

是否可以在php/python中创建一个无阻塞的HTTP客户端而根本不处理响应?

Is it possible to create a non-blocking HTTP client in php/python without handling the response at all?

对于我来说，最好使用在php和python中具有相同逻辑的解决方案.

A solution that will have the same logic in php and python is preferable for me.

谢谢

推荐答案

在PHP中，您可以通过发送此请求来关闭连接(这与HTTP有关，并且在python中也可以工作，尽管我不知道使用哪种正确的语法):

In PHP you can close the connection by sending this request (this is HTTP related and works also in python, although I don't know the proper syntax to use):

// Send the response to the client
header('Connection: Close');
// Do the background job: just don't output anything!

附录:我忘了提到您可能必须设置上下文长度".另外，请查看此评论以获得提示和真实的测试用例.

Addendum: I forgot to mention you probably have to set the "Context-Length". Also, check out this comment for tips and a real test case.

<?php    
ob_end_clean();
header('Connection: close');

ob_start();

echo 'Your stuff goes here...';

header('Content-Length: ' . ob_get_length());

ob_end_flush();
flush();

// Now we are in background mode
sleep(10);
echo 'This text should not be visible';    
?>
