我正在嘗試在 flask Web 套接字應(yīng)用的服務(wù)器端腳本中創(chuàng)建時間延遲。最終，我希望服務(wù)器能夠同時處理許多請求，并且能夠以固定的時間間隔向客戶端發(fā)出兩個數(shù)據(jù)包。當(dāng)我在兩個語句之間使用時，客戶端在睡眠完成后一起接收套接字發(fā)出事件。time.sleep(x)flask_socketio.emit如何在python燒瓶應(yīng)用程序中實現(xiàn)？Emit X; wait Y seconds; emit Z服務(wù)器端代碼摘錄：from flask import Flask, requestfrom flask_socketio import SocketIO, join_room, emitapp = Flask(__name__)socketio = SocketIO(app)@socketio.on('ping')def ping(appState):    """send 2 pings, between a time interval"""    room = appState["sessionID"]    emit('serverPingResponse', {'room': room, 'msg':"Ping Received by Server"})    time.sleep(5)    emit('serverPingResponse', {'room': room, 'msg':"2nd time-delayed ping"})    return客戶端代碼摘錄：var socket = io.connect('http://' + document.domain + ':' + location.port);socket.on("serverPingResponse", function(msg){      // listen to server ping and print the message to console      let d = new Date();      console.log("ping received at "+d.toLocaleTimeString(), msg)    });控制臺輸出pinging server...ping received at 10:43:14 AM Object { room: "wvdhj01f3p", msg: "Ping Received by Server" }ping received at 10:43:14 AM Object { room: "wvdhj01f3p", msg: "2nd time-delayed ping" }所需的輸出是接收第一個 ping，第二個 ping 在10:43:0910:43:14
