我遇到问题，无法使我的socket.io客户端从服务器正确接收带有自定义事件类型的消息。
当客户端成功连接后，我发出从服务器获取客户端用户ID的请求。在尝试在HTTP请求和WebSocket之间使用会话时遇到麻烦之后，我切换到通过jinja模板传递用户ID。
但是，现在我很难让客户端从服务器接收自定义类型的数据包。
controller.py
@socketio.on('connect')
def connect():
hello = 'Hello'
emit('get_user', hello, include_self=True)
socketio.sleep(0)
return
index.html *
<script>
const socket = io(SERVER_URL/PATH);
socket.on("get_user", function (data) {
console.log(data);
socket.emit("send_user", {{ user.id }});
</script>
服务器显示它正在“发出”具有正确类型的消息，但随后在将其作为消息发送之后。
然后，客户端仅接收到类型为"message"而不是类型为"get_user"的已发送消息>
问题是：如何使发射器正常工作？
任何帮助将不胜感激。谢谢！
编辑：发布其余代码。
