python实现群聊功能： 客户端能发送文本和文件消息(暂时支持文本和文件) 客户端每隔一秒向服务器请求最新的群消息（也就是服务器收到的所有客户端的消息）,如果有新消息，就显示出新消息 要求： 客户端采用QT5实现 客户端与服务端的通讯要求使用thrift

好的，以下是一个简单的Python实现群聊功能的示例：

客户端代码：

import sys
import time
import os
import thriftpy2
from thriftpy2.rpc import make_client
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWidgets import *

chat_thrift = thriftpy2.load("chat.thrift", module_name="chat_thrift")


class ChatClient(QWidget):
    def __init__(self):
        super().__init__()
        self.username = ""
        self.setup_ui()
        self.connect_server()

    def setup_ui(self):
        self.chat_record = QTextEdit()
        self.chat_record.setReadOnly(True)
        self.chat_input = QTextEdit()
        self.send_button = QPushButton("发送")
        self.file_button = QPushButton("发送文件")
        self.file_button.setEnabled(False)
        self.check_timer = QTimer(self)
        self.check_timer.timeout.connect(self.check_new_message)
        self.check_timer.start(1000)

        layout = QVBoxLayout()
        layout.addWidget(self.chat_record)
        layout.addWidget(self.chat_input)
        button_layout = QHBoxLayout()
        button_layout.addWidget(self.send_button)
        button_layout.addWidget(self.file_button)
        layout.addLayout(button_layout)
        self.setLayout(layout)

        self.setWindowTitle("群聊")
        self.resize(600, 400)

        self.send_button.clicked.connect(self.send_message)
        self.file_button.clicked.connect(self.send_file)

    def connect_server(self):
        self.client = make_client(chat_thrift.ChatService, "localhost", 9090)
        self.username, success = QInputDialog.getText(self, "登录", "请输入您的用户名：")
        if success:
            self.file_button.setEnabled(True)

    def send_message(self):
        message = self.chat_input.toPlainText()
        if message:
            self.client.send_message(self.username, message)
            self.chat_input.clear()

    def send_file(self):
        file_path, _ = QFileDialog.getOpenFileName(self, "选择文件", ".", "All files(*.*)")
        if file_path:
            with open(file_path, "rb") as f:
                file_data = f.read()
                file_name = os.path.basename(file_path)
                self.client.send_file(self.username, file_name, file_data)

    def check_new_message(self):
        new_messages = self.client.get_messages()
        if new_messages:
            for message in new_messages:
                sender, content = message.sender, message.content
                self.chat_record.append(f"{sender}: {content}")


if __name__ == '__main__':
    app = QApplication(sys.argv)
    client = ChatClient()
    client.show()
    sys.exit(app.exec_())

服务端代码：

import thriftpy2
from thriftpy2.rpc import make_server

chat_thrift = thriftpy2.load("chat.thrift", module_name="chat_thrift")


class ChatServiceHandler:
    def __init__(self):
        self.messages = []

    def send_message(self, sender, content):
        self.messages.append(chat_thrift.Message(sender=sender, content=content))
        print(f"{sender}: {content}")

    def send_file(self, sender, file_name, file_data):
        self.messages.append(chat_thrift.Message(sender=sender, content=f"发送了文件 {file_name}"))
        print(f"{sender} 发送了文件 {file_name}")

    def get_messages(self):
        messages = self.messages
        self.messages = []
        return messages


if __name__ == '__main__':
    handler = ChatServiceHandler()
    server = make_server(chat_thrift.ChatService, handler, "localhost", 9090)
    print("Starting the chat server...")
    server.serve()

其中，`chat.thrift`文件的内容如下：

namespace py chat_thrift

struct Message {
    1: string sender,
    2: string content,
}

service ChatService {
    void send_message(1: string sender, 2: string content),
    void send_file(1: string sender, 2: string file_name, 3: binary file_data),
    list<Message> get_messages(),
}

在启动服务端后，运行客户端即可进行群聊，每隔一秒钟会自动请求最新的群消息并显示出来。客户端可以发送文本消息和文件消息。
