做一个客户端 - 服务器应用程序 [英] make a Client-Server application

问题描述

我曾经在同一台电脑上建立网路应用程式，但如果伺服器和用户端不在同一台电脑上，我们如何存取网页？

I used to create web app in the same computer, but if the server and the client is not in the same computer, how can we access to the web page ?

我的意思是，例如我有一个html表单和一个按钮ok：
如果服务器和客户端在同一台计算机，在action =我们把localhost / file.py，但如果服务器和客户端不在同一台计算机上怎么做？因为客户端不能在他的webbrower（url）中有localhost。

I mean, for example I have an html form and a button "ok" : If the server and the client are in the same computer, in action = " " we put localhost/file.py , but if the server and the client are not in the same computer how to do this ? Because the client can't to have localhost in his webbrower (url).

推荐答案

您的脚本应该作为CGI脚本由Web服务器设置环境变量，如REMOTE_ADDR，REQUEST_METHOD ...

Your script is supposed to be run as a CGI script by a web-server, which sets environment variables like REMOTE_ADDR, REQUEST_METHOD ...

您正在自己运行脚本，并且此环境变量不可用。

You are running the script by yourself, and this environment variable are not available.

这就是为什么你得到KeyError。

That's why you get the KeyError.
