Socketio sleep

Changing the number of sleep statements always resulted in it not emitting anything after the last sleep. To add to the mystery, if I remove the sleep statements entirely, I don't see anything get emitted from the thread at all. I'm using the version 1.4.5 of Flask-socketio and eventlet as the async service. I tried replacing time.sleep() with eventlet.sleep(), but saw the same behavior Hi, I've been using flask-socketio for a few months and everything works great. I was always aware though that the emitted events were not received by my browser client in real-time. So after looking at other issues on GitHub, I learnt to do socketio.sleep(0) after emits or sends, and also monkey patching with either eventlet or gevent You can see from the various sleeps that I was short of sleep! Thanks, socketio.sleep it is then - and with socketio.sleep(1) it works, but I have seen a lot of reference to sleep(0) in other threads but sleep(0) doesn't work for me. For my purposes, sleep(1) is actually fine, but just so I learn and looking at the code, shouldn't sleep(0) also work sleep (seconds=0) ¶ Sleep for the requested amount of time using the appropriate async model. This is a utility function that applications can use to put a task to sleep without having to worry about using the correct call for the selected async mode Ich habe meinen Code überarbeitet und herausgefunden, dass das Wichtigste, was mir fehlte, ein socketio.sleep(0) oder ein socketio.sleep(0.01) was etwas besser funktioniert (nicht genau sicher warum). Dies muss sich in der Hintergrund-Thread-Schleife befinden. Ich denke, ich muss einige Async / Warten / Asyncio-Interna studieren, um ein besseres Verständnis der Schlafanrufe zu erhalten

SOCKET.IO 4.0 IS HERE. Socket.IO enables real-time, bidirectional and event-based communication. It works on every platform, browser or device, focusing equally on reliability and speed Flask-SocketIO gives Flask applications access to low latency bi-directional communications between the clients and the server. The client-side application can use any of the SocketIO client libraries in Javascript, Python, C++, Java and Swift, or any other compatible client to establish a permanent connection to the server. Introduction The socketio.Server.emit() method has an optional callback argument that can be set to a callable. If this argument is given, the callable will be invoked after the server has processed the event, and any values returned by the server handler will be passed as arguments to this function Ich glaube, ich habe eine Lösung gefunden. Ich habe einfach eine Instanz meiner App in der Methode notifications_job erstellt und den Anwendungskontext verschoben:. def notifications_job(): last_alert_id = None settings_module = os.getenv('FLASK_SETTINGS_MODULE') app = create_app(settings_module) while True: with app.app_context(): socketio.sleep(60) last_id = Alert.get_last_alert_id.

# 后台线程 产生数据,即刻推送至前端 def background_thread(): count = 0 while True: socketio.sleep(5) count += 1 t = time.strftime('%M:%S', time.localtime()) # 获取系统时间(只取分:秒) cpus = psutil.cpu_percent(interval=None, percpu=True) # 获取系统cpu使用率 non-blocking socketio.emit('server_response', {'data': [t, cpus], 'count': count}, namespace='/test') socketio.emit('messageEventNew', {'encryptkey':'key'}, namespace='/test') # 注意. Ask questions Socketio not emitting data even with socketio.sleep Your question I am creating an app, in which a route takes data from an object created to gather live trades data for an asset via a websocket server. I want to slightly process this data and feed it to clients via Flask-SocketIO and I have almost been successfull, with the exception that the loops (either for or while) seem to. gevent并发模式也比较简单:. task_1 (): gevent.sleep (1) print 'running task 1' task_2 (): gevent.sleep (1) print 'running task 2' gevent.addall ( [ gevent.spawn (task_1), gevent.spawn (task_2) ]) 上述的操作就是在gevent内孵化(spawn)两个协程,然后每个协程每一秒通过gevent.sleep ()让出gvent供其他的协程使用。. 通过这个模式,我们将emit并发事件修改为这样:

Flask 之SocketIO库的使用(绘图) - lyshark - 博客园

客户端使用socket.io.js,服务端使用flask-socketio扩展. 于是首先要pip安装flask-socketio. 然后: from flask_socketio import SocketIO socketio = SocketIO(app, async_mode= 'eventlet') socketio.run(app,host= '0.0.0.0') 像上边这样把原来的app启动改一下,eventlet是服务器,它支持websocket,必须要先pip安 Ich versuche, Flask SocketIO im Thread mit Python 3 auszuführen, aber ich kann es nicht zum Laufen bringen.

WebScoket 通信技术作用是让客户端和服务器之间能进行双向实时通信,它是HTML最新标准H5的协议规范,本质上是个基于TCP的协议,它通过HTTP/HTTPS协议发送一条特殊的请求进行握手后创建了一个TCP连接,此后浏览器/客户端和服务器之间便可以通过此连接来进行双向实时通信,通过使用WebSocket通信技术,可以实现实时数据同步,在动态图表绘制方面贡献巨大 sleep(seconds=0) Sleep for the requested amount of time using the appropriate async model.

The main difference between Flask-Sockets and Flask-SocketIO is that the former wraps the native WebSocket protocol (through the use of the gevent-websocket project), so it can only be used by the most modern browsers that have native support.

socketio.sleep(3) 实际上这种方法还是同步的,整个流程的发起还是web,并没有实现正真意义上的互相通信。但是也可以解决现有问题。 2、使用app.app_context(),其实socketio.emit()没有发送成功是因为没有找到app的上下文,使用withapp.app_context()即可以找到app的上下文。但是要注意的是线程中的挂起方式还是得用.

You use a large number of call to Thread.sleep () in your code, this is more like a anti-pattern for proper usage of locking. In the ideal world, you should let the threads wait for each other using Object.wait () in combination with Object.notifyAll (). Incase of your socket, don't sleep, but call the read () method again

gevent是第三方库,通过greenlet实现协程,其基本思想是:. 当一个greenlet遇到IO操作时,比如访问网络,就自动切换到其他的greenlet,等到IO操作完成,再在适当的时候切换回来继续执行。. 由于IO操作非常耗时,经常使程序处于等待状态,有了gevent为我们自动切换协.

Hi all, I am trying to set up a ROS2 rclpy node that functions as a Flask socket server. This node needs to have a thread or timer-based process running (which handles a socket broadcast). The issue I am running into is that when I create a ROS2 timer, it seems that it never executes, and when I use a python thread, it seems to block the main process Introduction. In this tutorial we will check how to control a relay connected to the ESP32 remotely, using sockets. The code will be developed using the Arduino core.
