如何在应用程序启动时向 EndPoint 发送请求

Question

I am working on a Django project which has an API endpoint that receives a post request and sends a welcome email to the registered user, currently, I have to use a form to send this request to the endpoint, is there a way to manually read the email and name from my environmental variable and send a request once I run the app the first time? something like

EMAIL = 'try@test.com'
NAME = 'Bob'

I have this stored as an env variable already

and here is my current code

@require_http_methods(["POST"])
@login_required
def add_user(request):
    if request.is_ajax():
        name = request.POST.get('name')
        email = request.POST.get('email')
        if not BlueUsers.objects.filter(user_email=email).exists():
            newuser_obj = BlueUsers.objects.create(user_name=name, user_email=email)
            conf_obj = Config.objects.first()
            if conf_obj:
                post_url = "{}/priv/create-user/".format(conf_obj.hostname)
                data = {
                    'name': newuser_obj.user_name,
                    'email': newuser_obj.user_email,
                    'redtree_user_id': newuser_obj.id
                }
                headers = {'data-auth-key': conf_obj.authentication_token}
                try:
                    response = requests.post(post_url, data=data, headers=headers)
                except:
                    response = None

I have been struggling with this

There is a file name apps.py that loads your app configuration and runs code on app startup.

Your purpose should be served by following piece of code

class MyAppConfig(AppConfig):
    name = "myapp"

    def ready(self):
        # your model and other imports here

        email = os.environ.get('EMAIL')
        name = os.environ.get('NAME')

        if not BlueUsers.objects.filter(user_email=email).exists():
            newuser_obj = BlueUsers.objects.create(user_name=name, user_email=email)
            conf_obj = Config.objects.first()
            if conf_obj:
                post_url = "{}/priv/create-user/".format(conf_obj.hostname)
                data = {
                    'name': newuser_obj.user_name,
                    'email': newuser_obj.user_email,
                    'redtree_user_id': newuser_obj.id
                }
                headers = {'data-auth-key': conf_obj.authentication_token}
                try:
                    response = requests.post(post_url, data=data, headers=headers)
                except:
                    response = None

Any logic that you write inside the ready method of your AppConfig class is going to be executed once on each startup.
