python - Python SimpleHTTPRequestHandler 播放声音异步

问题描述

我不知道如何让这个小型 http 服务器回复 get 请求并并行播放声音。

当前代码，直到声音 "winsound.PlaySound("SystemExit", winsound.SND_ALIAS)" 结束播放才关闭获取请求。

我需要的是声音与请求异步，以便获取请求尽快结束并且声音继续播放。

#!/usr/bin/env python3

from http.server import HTTPServer, SimpleHTTPRequestHandler, test
import socketserver
from urllib.parse import urlparse
from urllib.parse import parse_qs
import sys
import winsound



class MyHttpRequestHandler(SimpleHTTPRequestHandler):
    try:

        def do_GET(self):
            # Sending an '200 OK' response
            self.send_response(200)

            # Setting the header
            self.send_header("Content-type", "text/html")

            # Whenever using 'send_header', you also have to call 'end_headers'
            self.end_headers()


            html = "ok"
            # Writing the HTML contents with UTF-8
            self.wfile.write(bytes(html, "utf8"))            
            winsound.PlaySound("SystemExit", winsound.SND_ALIAS)

            return

    except Exception as e:
        print(str(e))



# Create an object of the above class
handler_object = MyHttpRequestHandler

PORT = 8000
my_server = socketserver.TCPServer(("", PORT), handler_object)

# Star the server
my_server.serve_forever()

解决方案

使用一个标志来异步运行它：

winsound.PlaySound("SystemExit", winsound.SND_ALIAS|winsound.SND_ASYNC)

如果您希望进行更严格的控制，请使用concurrent.futures.ThreadPoolExecutor()在不同的线程中运行它：

from concurrent.futures import ThreadPoolExecutor
import winsound

pool = ThreadPoolExecutor()

class MyHttpRequestHandler(SimpleHTTPRequestHandler):
    try:

        def do_GET(self):
            # Sending an '200 OK' response
            self.send_response(200)

            # Setting the header
            self.send_header("Content-type", "text/html")

            # Whenever using 'send_header', you also have to call 'end_headers'
            self.end_headers()


            html = "ok"
            # Writing the HTML contents with UTF-8
            self.wfile.write(bytes(html, "utf8"))

            pool.submit(winsound.PlaySound, "SystemExit", winsound.SND_ALIAS)

            return

    except Exception as e:
        print(str(e))
