我应该使用什么 Bearer 令牌进行 Firebase 云消息传递测试? [英] What Bearer token should I be using for Firebase Cloud Messaging testing?

问题描述

我正在尝试通过 Postman 使用 Firebase Cloud Messaging 发送测试通知.我正在对这个 url 做一个 POST

https://fcm.googleapis.com/v1/projects/[我的项目名称]/messages:send

Postman 中的 Authorization 选项卡设置为 No Auth，而我的 Headers 选项卡如下所示

内容类型:application/json授权:Bearer [服务器密钥]

[服务器密钥] 是我的 Firebase 项目设置"区域的云消息传递"选项卡中新生成的服务器密钥.我不断收到此错误作为响应.

错误":{代码":401，"message": "请求具有无效的身份验证凭据.需要 OAuth 2 访问令牌、登录 cookie 或其他有效的身份验证凭据.请参阅 https://developers.google.com/identity/sign-in/web/devconsole-project.",状态":未经身份验证"}

根据我能找到的一切，我使用了正确的令牌，但 Google 似乎不同意.我应该发送什么作为 Authorization 标头来解决此错误?

解决方案

获取Authentication Bearer的步骤:

1. 访问 Google OAuth Playground:

   如果您想使用 cURL，用于数据通知:

   curl --location --request POST 'https://fcm.googleapis.com/v1/projects/your-project-id/messages:send' --header '内容类型:应用程序/json' --header '授权:承载你的访问令牌-*****-wqewe' --data-raw '{消息":{令牌":设备令牌-qwfqwee-***-qefwe"，数据":{Key1":val1"，Key2":val2"；}}}'

   I am trying to send a test notification using Firebase Cloud Messaging via Postman. I'm doing a POST to this url

   https://fcm.googleapis.com/v1/projects/[my project name]/messages:send
   

   The Authorization tab in Postman is set to No Auth and my Headers tab looks like this

   Content-Type: application/json
   Authorization: Bearer [server key]
   

   [server key] is a newly generated server key in the 'Cloud Messaging' tab of my Firebase project's 'Settings' area. I keep getting this error in response.

   "error": {
       "code": 401,
       "message": "Request had invalid authentication credentials. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
       "status": "UNAUTHENTICATED"
   }
   

   Based on everything I can find, I'm using the right token, but it seems Google disagrees. What should I be sending as the Authorization header to get past this error?

   解决方案

   Steps to get Authentication Bearer:

   1. Got to Google OAuth Playground: https://developers.google.com/oauthplayground
   2. In the "Input your own scopes" for FCM use this url: https://www.googleapis.com/auth/firebase.messaging
   3. Tap Authorize API.
   4. Pick correct user for authorisation and allow access.
   5. In the Step 2: Exchange authorization code for tokens tap Exchange authorisation code for tokens.
   6. Access token is your Bearer.

   Steps to send FCM throw Postman:

   1. URL to send: https://fcm.googleapis.com/v1/projects/projectid-34543/messages:send
   2. Request Type: POST
   3. Headers: Content-Type -> application/json & Authorization -> Bearer
   4. In the body section enter APS payload with the right device token.
   5. Click send.

   In case you want to use cURL, for a data-notification:

   curl --location --request POST 'https://fcm.googleapis.com/v1/projects/your-project-id/messages:send' 
   --header 'Content-Type: application/json' 
   --header 'Authorization: Bearer your-access-token-*****-wqewe' 
   --data-raw '{
       "message": {
           "token": "device-token-qwfqwee-***-qefwe",
           "data": {
               "Key1": "val1",
               "Key2": "val2"
           }
       }
   }'
