我有一個處理傳感器數據的本地燒瓶服務器。當溫度大于某個閾值時,它會獲取溫度值并調整燈光。到目前為止,它僅在一個客戶端保持瀏覽器打開該頁面時才有效。如果服務器可以在不一直打開瀏覽器的情況下更新溫度值并調整光線,那就太好了。如何讓它在后臺運行?temperture = 0threshold_temp = 0def read_temp(): #read temperature valuesserver = Flask(__name__)socketio = SocketIO(server)app = dash.Dash(__name__, server = server, url_base_pathname="/dash/")@server.route('/_stuff')def stuff(): global threshold_temp temperature = read_temp() if temperature >= threshold_temp: #change light else: #do not change light return jsonify(result = temperature)#Change [email protected]('message')def handleMessage(msg): global threshold_temp threshold_temp = float(msg) send(msg, broadcast=True) f = open("Threshold.txt", "w") f.write(msg) f.close()#Adjust Threshold on Connection of [email protected]('connect')def on_connect(): global threshold_temp f = open("Threshold.txt", "r") threshold_temp = float(f.read()) send(threshold_temp, broadcast=True)@server.route('/')def index(): return render_template('index.html')if __name__ == '__main__': socketio.run(server, host='0.0.0.0', port=80, debug=False)
在瀏覽器中保持 Flask 在沒有網頁的情況下運行
