Question

我的设置是我在本地计算机上运行python socket.io客户端，并在GCP实例上运行服务器。我正在使用基本的socket.io教程代码。问题是客户端将连接到实例，但无法发出。这是客户端和服务器片段。

http_client.py

import socketio
client = socketio.Client()

@client.event
def connect():
    print('Client: connected')

@client.event
def disconnect():
    print('Client: disconnected')

@client.event
def basicReply():
    print(f"From Server: basic reply")

if __name__ == '__main__':
    client.connect("http://35.229.56.147:80")       # ephemeral IP
    client.emit('basicMessage')
    client.sleep(2)
    client.disconnect()

http_server.py

import socketio
server = socketio.Server()
wsgi_app = socketio.WSGIApp(server)

@server.event
def connect(sid, environ):
    print(f"Server: connected {sid[:6]}")

@server.event
def disconnect(sid):
    print(f"Server: disconnected {sid[:6]}")

@server.event
def basicMessage(sid):
    print(f"From client: basic message")
    server.emit('basicReply')

我正在使用2个不同的实例来解释此问题。第一个是具有GPU的常规Compute Engine VM（使用python 3.6）。第二个是Deep Learning VM（使用我安装的python 3.8）。对于常规VM，http通信正常运行。但是对于深度学习，客户端可以连接但不能发出信号。

客户端连接到常规Compute Engine

(v2) C:\Projects\MicroServer\CodeBase\server>python http_client.py
Client: connected
From Server: basic reply

常规Compute Engine上的服务器

客户端连接到深度学习VM

(v2) C:\Projects\MicroServer\CodeBase\server>python http_client.py
Client: connected

深度学习VM上的

服务器

如您所见，客户端连接但在深度学习服务器上不发光。代码正在运行，服务器在其实例上运行，并且防火墙规则设置为允许http：80。为什么它在深度学习VM上不起作用？

socket.io可以连接但不能在GCP深度学习VM上发出
