使用flask_socketio搭建一个ws程序，运行后服务端报错
The client is using an unsupported version of the Socket.IO or Engine.IO protocols (further occurrences of this error will be logged with level INFO)
以下是代码
服务端：
from flask import Flask, render_template
from flask_socketio import SocketIO,emit
from threading import Lock
import random
async_mode = None
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app)
thread = None
thread_lock = Lock()
@app.route('/')
def index():
return render_template('app.html')
@socketio.on('connect', namespace='/test_conn')
def test_connect():
global thread
with thread_lock:
if thread is None:
thread = socketio.start_background_task(target=background_thread)
def background_thread():
while True:
socketio.sleep(5)
t = random.randint(1, 100)
socketio.emit('server_response',
{'data': t},namespace='/test_conn')
if __name__ == '__main__':
socketio.run(app, debug=True)

});
});

如果是版本问题，请问应该下载那个版本呢？
客户端的使用了 Socket.IO 或 Engine.IO protocols 不支持的版本，建议升级版本即可。下载最新或次新的版本即可，新版本都是向下兼容的，所以下新的版本一般都没有错。 望采纳，望采纳，祝你的问题早日解决！！！
