python Flet 订阅广播无法正常收到对方消息，怎么解决?-灵析社区

## 基于flet官方例子修改成异步的订阅后，只能收到发送方自己的消息，求助！ import flet as ft import flet_fastapi async def main(page: ft.Page): page.title = "Flet Chat" async def on_message_async(msg): messages.controls.append(ft.Text(msg)) await page.update_async() await page.pubsub.subscribe_async(on_message_async) async def send_click(e): await page.pubsub.send_all_async(f"{message.value}") message.value = "" await page.update_async() messages = ft.Column() message = ft.TextField(hint_text="Your message...", expand=True) send = ft.ElevatedButton("Send", on_click=send_click) await page.add_async(messages, ft.Row(controls=[message, send])) #ft.app(target=main, view=ft.AppView.WEB_BROWSER) app = flet_fastapi.app(main) # You only get your own messages 使用 ft.app(target=main, view=ft.AppView.WEB_BROWSER) 正常，但无法部署到服务端。
