使用 Flask-socketio 和 socketIO 客户端
Using Flask-socketio and the socketIO client
我目前正在尝试了解套接字的工作原理。我正在通过一个基本示例使用 Flask-socketio 和 python socketio 客户端和 运行ning。这是我到目前为止所做的
app.py
from flask import Flask, render_template
from flask_socketio import SocketIO, emit
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app)
@socketio.on('aaa')
def test_connect():
print("Welcome, aaa received")
emit('aaa_response', {'data': 'Server'})
if __name__ == '__main__':
socketio.run(app, port=8000)
client.py
from socketIO_client import SocketIO, LoggingNamespace
def on_aaa_response(args):
print('on_aaa_response', args['data'])
socketIO = SocketIO('localhost', 8000, LoggingNamespace)
socketIO.on('aaa_response', on_aaa_response)
socketIO.emit('aaa')
socketIO.wait(seconds=1)
我在 运行 client.py
时遇到断言错误。不过,我确实看到服务器正在打印 "Welcome, aaa recived"
。我不知道我在这里做错了什么,如果那是我的日志
错误日志

根据堆栈跟踪,我无法识别您正在使用的 socketIO-client
包的版本。它似乎不是当前版本。
我已经在这里测试了你的两个应用程序,它们似乎在客户端的 0.7.2 版本上工作得很好。我建议你 运行 pip install --upgrade socketIO-client==0.7.2
然后再试一次。
