我正试图创建一个房间，并通过emit在客户端获得输出，但似乎不起作用。你能告诉我它怎么了吗？
我认为这是错误，但我不明白这意味着什么：-
参与者=ns[room[0]_fwdm.copy((如果ns else｛｝中的room[0]TypeError:"int"对象不是可下标的
文件"E： \KabirProject\WebsocketDocs\app.py"；，第36行，在join_roomm中emit("room joined"，"Hey I have joind the room"，to=room(
这里是我的服务器端代码：-
from flask import Flask, render_template
from flask_socketio import SocketIO, send, emit, join_room
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app)
client = 0
@app.route('/')
def welcome():
return render_template('index.html')
@app.route('/home')
def home():
return render_template('home.html')
@socketio.on('connect')
def connect_handerler(data):
global client
client = client +1
print(f"nn {client}nn")
@socketio.on('disconnect')
def disconnect_handeler():
global client
client = client -1
print(f"nn {client}nn")
@socketio.on('join')
def join_roomm(data):
room = data['room']
join_room(room)
emit('room joined', "Heyy I've joined the room", to = room) //Line 36
if __name__ == '__main__':
socketio.run(app, debug = True)
以下是我的客户端代码：-
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Index</title>
</head>
<body>
Index
<button onclick="room(1)">
Room1
</button>
<button onclick="room(2)">
Room2
</button>
<button id="message" onclick="message()">Send a message to server</button>

var socket = io();
socket.on('clients count', function(client){
// console.log(client);
});
socket.on('message', function(data){
console.log(data);
});
function room(id){
// console.log(id);
socket.emit('join',{"room": id});
};
socket.on('room joined', function(data){
console.log(data);
});
</script>

这是我得到的错误：-

TypeError: 'int' object is not subscriptable
发生这种情况是因为我试图在to参数中传递一个整数，我认为它只接受字符串，所以当我开始传递字符串时，它就开始工作了。
