在我的烧瓶应用中使用socketio，我想显示发件人和消息的名称，但这里只显示消息，发件人的名字只在浏览器中显示“[object object] hello” 。Python烧瓶广播消息

**# server.py 

    from flask import Flask, render_template 
    from flask_socketio import SocketIO, emit 

    app = Flask(__name__) 

    app.config[ 'SECRET_KEY' ] = 'jsbcfsbfjefebw237u3gdbdc' 
    socketio = SocketIO(app) 

    @app.route('/') 
    def hello(): 
     return render_template('./index.html') 

    def messageRecived(): 
     print('message was received!!!') 

    @socketio.on('my event') 
    def handle_my_custom_event(json): 
     print('recived my event: ' + str(json)) 
     socketio.emit('my response', json, callback=messageRecived) 

    if __name__ == '__main__': 
     socketio.run(app, debug = True)

请停止恢复编辑，您的原始格式非常糟糕。将代码块*格式化为代码块*，而不是引号。 – jonrsharpe

您要发送DOM元素添加到服务器，而不是它的内容。添加.text()以获取实际用户名：

socket.emit('my event', { 
     username : $("#username").text(), 
     message : user_input 
    })
