為 Django 視圖執行設置計時器

[英]Set timer for a Django view execution

我正在努力阻止 Django 視圖在一小時內執行多次。 換句話說,如果 function 在 15:00 運行,則所有用戶的所有未來請求都應被忽略,直到 17:00 允許再次運行。

嘗試使用計時器,但每次調用視圖時都會重置。 也許有人可以指出我正確的方向? 謝謝!!!

import threading as th

def hello():
    print("hello, world")


def webhook(request):
   
   tm = th.Timer(3600, hello)
    
    if request.method == 'POST' and not tm.is_alive():
        
        tm.start()
        
        code_to.ecexute()

        return HttpResponse("Webhook received!")

最終,這就是我所做的,它似乎工作正常。 我實際上需要它每天運行不超過一次,因此有以下條件。

感謝所有的建議!!!

def webhook2 (request):
    today = datetime.now().date()
    with open('timestamp.txt') as f:
        tstamp = f.read()
        last_run = datetime.strptime(tstamp, '%Y-%m-%d')
        last_run_date = datetime.date(last_run)
        print ("last run: " + str(last_run_date))
        

    if last_run_date < today:

        
        file = open("timestamp.txt" ,"w")
        file.write(str(today))
        file.close()

        if request.method == 'POST':
            msg = str(request.body)
            final_msg=msg[2:-1]
            print("Data received from Webhook is: ", request.body)

            # creates a google calendar event
            function_logic()

            return HttpResponse("Webhook received! Event added to calendar")
    
    
    else:
        print ("we already have a record for today")

        return HttpResponse("Not adding a record. We already have one for today.")

您的計時器每次都會被重置,因為它位於每次發出請求時都會執行的 function 內。 您應該嘗試全局設置計時器,例如在 function 之外。 (請注意,當您的腳本重新運行時,計時器將再次重置)。

import threading as th

def hello():
    print("hello, world")

tm = None

def webhook(request):
   
    # check here if timer is dead then process the request.
    if timer_is_dead || tm is None:
        
        # accessing global value and setting it for first time
        if tm is None:
            global tm
            tm =  th.Timer(3600, hello)
            tm.start()
        
        if request.method == 'POST' and not tm.is_alive():
     
            code_to.ecexute()

            # start timer again for next hour
            
            return HttpResponse("Webhook received!")
    else:
        return HttResponse("Not Allowed")

編輯:處理第一個請求,然后啟動計時器
