如何发送 HTTP 请求以在 firebase 中发送通知？

Question

To send a notification, you'll need to send the following HTTP request:

 POST /fcm/send HTTP/1.1 Host: fcm.googleapis.com Content-Type: application/json Authorization: key=YOUR_SERVER_KEY { "notification": { "title": "New chat message,": "body", "There is a new message in FriendlyChat": "icon". "/images/profile_placeholder,png": "click_action": "http://localhost,5000" }: "to":"YOUR_DEVICE_TOKEN" }

how can I do this??

Answer 1

If you're using Node.JS, I suggest you look at the documentation for Firebase's Node.JS SDK instead of manually sending HTTP requests. There's the official documentation or this nice tutorial

If you still want to go for the plain HTTP method, you can use the request npm module

$ npm install request

then in your code :

const request = require('request');

request({
  url: 'https://fcm.googleapis.com/fcm/send',
  method: 'POST',
  headers: {
    "Content-Type": "application/json",
    "Authorization": ['key', yourServerKey].join('=')
  },
  json: {
    to: clientFirebaseToken,
    notification: {
      title: "Notification Title",
      body: "This is a neat little notification, right ?"
    }
  });

Edit

From their GitHub

As of Feb 11th 2020, request is fully deprecated. No new changes are expected to land. In fact, none have landed for some time.

If you use axios

axios({
  method: 'post',
  url: 'https://fcm.googleapis.com/fcm/send',
  headers: {
    "Content-Type": "application/json",
    "Authorization": ['key', yourServerKey].join('=')
  },
  params: {
    to: clientFirebaseToken,
    notification: {
      title: "Notification Title",
      body: "Neat indeed !"
    }
  }
})

If you are using React JS/ React Native, using the Axios package it can be done very easily, the sample code is below, first, you have to register for firebase cloud messaging to get the authorization key

axios.post(
          'https://fcm.googleapis.com/fcm/send',
          {
            data: {},
            notification: {
              title: "Sample text1",
              body: "Sample text2",
              image: "Sample text3",
            },
            to: '/topics/TopicName',
          },
          {
            headers: {
              Authorization:
                'key=Authorization key from firebase',
              
            },
          },
        )
        .then(Response => {
          console.log(Response.data);
        });
