python - 如何关闭python服务器

Question

使用此代码运行 python 服务器:

import os
from http.server import SimpleHTTPRequestHandler, HTTPServer                                                                                                                                   

os.chdir('c:/users/owner/desktop/tom/tomsEnyo2.5-May27')                                                                                                                                                                                      
server_address = ('', 8000)                                                                                                                                                                    
httpd = HTTPServer(server_address, SimpleHTTPRequestHandler)                                                                                                                                   
httpd.serve_forever()

如何让它停止？

您的问题不明确 - 如果您通过 shell 即 python myscript.py 运行服务器，只需按 crtl + C。

如果你想用代码优雅地关闭它，你必须决定一些条件，或者点，或者异常来调用它关闭。您可以添加一个 block 并调用 httpd.shutdown() - 作为 HttpServer 本身就是一个 SocketServer.TCPSServer 子类:

The first class, HTTPServer, is a SocketServer.TCPServer subclass, and therefore implements the SocketServer.BaseServer interface. It creates and listens at the HTTP socket, dispatching the requests to a handler.

所以 BaseServer 有一个方法 shutdown() ，因此作为 HttpServer 的子类也有它。

例如:

import os
from http.server import SimpleHTTPRequestHandler, HTTPServer                                                                                                                                   

os.chdir('c:/users/owner/desktop/tom/tomsEnyo2.5-May27')                                                                                                                                                                                      
server_address = ('', 8000)   
try:
    httpd = HTTPServer(server_address, SimpleHTTPRequestHandler)                                                                                                                                   
    httpd.serve_forever()
except Exception:
    httpd.shutdown()
