basehttpserver不响应其他请求

Question

当我同时在Android (192.168.1.4)和pc上打开我的本地服务器时，pc永远不会显示页面(它正在加载和加载...)-当我关闭我的服务器时，这个错误就会出现：

Exception happened during processing of request from ('192.168.1.4', 54734)
Traceback (most recent call last):
  File "/usr/lib/python2.7/SocketServer.py", line 295, in _handle_request_noblock

  File "/usr/lib/python2.7/socket.py", line 476, in readline
    data = self._sock.recv(self._rbufsize)
KeyboardInterrupt

我的服务器脚本：

# !/usr/bin/env python
# -*- coding: utf-8 -*-
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer

PORT = 20000


class S(BaseHTTPRequestHandler):
    def log_message(self, format, *args):
        return

    def _set_headers(self):
        self.send_response(200)
        self.send_header('Content-type', 'text/html')
        self.send_header('Access-Control-Allow-Origin', '*')
        self.end_headers()

    def do_GET(self):
        self._set_headers()
        if self.path == "/other":
            self.wfile.write("other")

        if self.path == "/something":
            self.wfile.write('something')

    def do_HEAD(self):
        self._set_headers()

    def do_POST(self):
        self._set_headers()
        self.wfile.write("hello post")


def run(server_class=HTTPServer, handler_class=S, port=PORT):
    server_address = ('', port)
    httpd = server_class(server_address, handler_class)
    httpd.serve_forever()


if __name__ == "__main__":
    from sys import argv

    if len(argv) == 2:
        run(port=int(argv[1]))
    else:
        run()

我的代码出了什么问题？

Answer 1

我认为你的服务器运行得很好:像任何服务器一样，它可以无限地运行。

要查看它的工作情况，只需将您的浏览器指向以下网址：http://localhost:20000/something或http://127.0.0.1:20000/something。

你应该得到文本"something“。

您应该考虑使用Flask。

不知道这是不是正确的方法，但是设置超时很有帮助：

...
        def log_message(self, format, *args):
            return
        def setup(self):
            BaseHTTPRequestHandler.setup(self)
            self.request.settimeout(0.5)
...

https://pymotw.com/2/BaseHTTPServer/#threading-and-forking说：

HTTPServer是SocketServer.TCPServer的一个简单子类，不使用多个线程或进程来处理请求。要添加线程或分支，请使用来自SocketServer的适当混合创建一个新类。
