如何在特定时间发送FCM通知？

Question

I can be able to send FCM notifications to single or multiple devices through PyFCM instantly.

# Send to single device.
from pyfcm import FCMNotification

push_service = FCMNotification(api_key="<api-key>")

# OR initialize with proxies

proxy_dict = {
          "http"  : "http://127.0.0.1",
          "https" : "http://127.0.0.1",
        }
push_service = FCMNotification(api_key="<api-key>", proxy_dict=proxy_dict)

# Your api-key can be gotten from:  https://console.firebase.google.com/project/<project-name>/settings/cloudmessaging

registration_id = "<device registration_id>"
message_title = "Uber update"
message_body = "Hi john, your customized news for today is ready"
result = push_service.notify_single_device(registration_id=registration_id, message_title=message_title, message_body=message_body)
print result

But I can't find a way to send notification to devices at specific time, say 03-10-2016 16:00:00 .

Answer 1

If you're looking for a public API of FCM for a scheduled push or a payload parameter where you can set the push date, unfortunately, there's nothing like it as of the moment.

You must implement your own App Server and implement the scheduled push yourself (also mentioned it here ).
