python - 如何运行服务于特定路径的 http 服务器？

Question

这是我的 Python3 项目层次结构:

projet
  \
  script.py
  web
    \
    index.html

从 script.py，我想运行一个 http 服务器来提供 web 文件夹的内容。

Here建议使用此代码运行一个简单的 http 服务器:

import http.server
import socketserver

PORT = 8000
Handler = http.server.SimpleHTTPRequestHandler
httpd = socketserver.TCPServer(("", PORT), Handler)
print("serving at port", PORT)
httpd.serve_forever()

但这实际上服务于 project，而不是 web。如何指定要服务的文件夹的路径？

在 Python 3.7 中 SimpleHTTPRequestHandler can take a directory argument :

import http.server
import socketserver

PORT = 8000
DIRECTORY = "web"


class Handler(http.server.SimpleHTTPRequestHandler):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, directory=DIRECTORY, **kwargs)


with socketserver.TCPServer(("", PORT), Handler) as httpd:
    print("serving at port", PORT)
    httpd.serve_forever()

从命令行:

python -m http.server --directory web

有点疯狂...您可以为任意目录创建处理程序:

def handler_from(directory):
    def _init(self, *args, **kwargs):
        return http.server.SimpleHTTPRequestHandler.__init__(self, *args, directory=self.directory, **kwargs)
    return type(f'HandlerFrom<{directory}>',
                (http.server.SimpleHTTPRequestHandler,),
                {'__init__': _init, 'directory': directory})


with socketserver.TCPServer(("", PORT), handler_from("web")) as httpd:
    print("serving at port", PORT)
    httpd.serve_forever()
