如何发送来自 Google Apps 脚本的 POST 数据？

Question

I used Firebase Cloud Messaging as a way to have push notifications in my web app. So now I am using Postman as a way to send my push notifications but i only send it manually

From google apps script I need to send my push notification.

This is what I use in Postman which has no problem and it works

This is from my Google apps script

function firebaseNotification() {

  var headers = { 
    "Authorization" : "key=key",
    "Content-Type" : "application/json"
  };

  var options =
   {
      "notification": {
        "title": "CWMS",
        "body": "from google apps scritpt",
        "click_action": "site",
        "icon": "http://url-to-an-icon/icon.png"
    },
    "to": "key"
   };

  var response = UrlFetchApp.fetch("https://fcm.googleapis.com/fcm/send", options);  

}

What needs to happen is that from Google Apps Script function firebaseNotification() but be triggered there and can POST the data needed and the web app to receive the push notification

How about this modification?

Modified script:

function firebaseNotification() {
  var headers = {
    "Authorization" : "key=key"
  };

  // Modified
  var payload = {
    "notification": {
      "title": "CWMS",
      "body": "from google apps scritpt",
      "click_action": "site",
      "icon": "http://url-to-an-icon/icon.png"
    },
    "to": "key"
  };

  // Modified
  var options = {
    method: "POST",
    contentType: "application/json",
    headers: headers,
    payload: JSON.stringify(payload) // <--- Modified
  }

  var response = UrlFetchApp.fetch("https://fcm.googleapis.com/fcm/send", options);
}

Reference:

• fetch(url, params)
