pyqt5 实现httpserver

可以使用 Python 标准库 `http.server`，具体实现代码可以参考以下代码：

import sys
from http.server import HTTPServer, SimpleHTTPRequestHandler
from PyQt5.QtCore import QUrl
from PyQt5.QtNetwork import QNetworkAccessManager, QNetworkReply
from PyQt5.QtWidgets import QApplication

class HttpHandler(SimpleHTTPRequestHandler):
    def do_GET(self):
        if self.path == '/':
            self.path = 'index.html'
        return SimpleHTTPRequestHandler.do_GET(self)

class HttpServer:
    def __init__(self, port):
        self.port = port
        self.httpd = HTTPServer(('localhost', self.port), HttpHandler)

    def start(self):
        self.httpd.serve_forever()

app = QApplication(sys.argv)
network_manager = QNetworkAccessManager()

def request_finished(reply):
    print(reply.readAll().data().decode())

url = QUrl('http://localhost:8080')
reply = network_manager.get(QNetworkRequest(url))
reply.finished.connect(request_finished)

server = HttpServer(8080)
server.start()

sys.exit(app.exec_())

该实现基于 Python 的标准库 `http.server`，并通过 PyQt5 实现了一个简单的 HTTP 客户端，可以在本地访问运行的 HTTP 服务器，并从该服务器获取数据。
