Führen Sie einen einfachen Flask -Web -Socket auf Render aus ⇐ Python

[Anonymous]

Ich bin neu zu rendern und ich mache einen einfachen Flask -Web -Socket < /p>
Ich verwende diese Module:
, Flask_Socketio
, Flask
, Gunicorn (um mein Skript auf Render -Host auszuführen) < /p>
Hier ist mein Code für Server -Seite: < /p> < /p> < /p>
Hier ist mein Code für Server.

Code: Select all

from flask import Flask
from flask_socketio import SocketIO , emit

app = Flask("application")
socket = SocketIO(app)

@app.route("/")
def home():
return "This is the server side !!"

@socket.on("connect")
def cl_con():
print("A new client connected !!")

@socket.on("disconnect")
def cl_dis():
print("A client disconnected !!")

@socket.on("message")
def message(data):
emit("message",data)

if __name__ == "__main__":
socket.run(app)
< /code>
und meine Client -Seite: < /p>
import socketio as io
import threading as th

name = ""

while (name == ""):
name = input("Your name :")

def message():
while True:
msg = input()
if (msg == "exit"):
client.disconnect()
print("Disconnected !!")
exit(0)
else:
client.emit("message",f"{name}:{msg}")

client = io.Client()

client.connect("https://my_domain_name.onrender.com")
client.emit("message",f"{name} join this chat !!")

t = th.Thread(target=message)
t.daemon = True
t.start()

@client.on("message")
def msg(data):
print(data)

client.wait()
< /code>
Ich versuche, mit meinem Client-Code eine Verbindung zu Web-Socket herzustellen, die auf meinem Computer ausgeführt wird.  Das [url=viewtopic.php?t=15738]Problem[/url] ist jedoch: < /p>
1- Nach 10 Sekunden-Serverseite geben Sie diesen Fehler weiter und zeigt diesen Fehler weiterhin alle 5 Sekunden: < /p>
