普通英语的WSGI和CGI是什么？ [英] What are WSGI and CGI in plain English?

问题描述

每次阅读WSGI或CGI时，我都会感到畏缩。我曾经尝试阅读过它，但没有任何东西卡住。

Every time I read either WSGI or CGI I cringe. I've tried reading on it before but nothing really has stuck.

用简单的英语到底是什么？

What is it really in plain English?

是否只是将请求传递到终端并重定向输出？

Does it just pipe requests to a terminal and redirect the output?

推荐答案

WSGI在Web服务器启动时运行Python解释器，作为Web服务器进程的一部分（嵌入式模式）或作为单独的进程（守护程序模式），并将脚本加载到其中。每个请求都会在脚本中调用一个特定的函数，并将请求环境作为参数传递给该函数。

WSGI runs the Python interpreter on web server start, either as part of the web server process (embedded mode) or as a separate process (daemon mode), and loads the script into it. Each request results in a specific function in the script being called, with the request environment passed as arguments to the function.

CGI将脚本作为每个请求的单独进程运行，并且使用环境变量，stdin和stdout与它通信。

CGI runs the script as a separate process each request and uses environment variables, stdin, and stdout to "communicate" with it.
