我应该使用什么Bearer令牌进行Firebase Cloud Messaging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.我正在对此URL进行POST

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

邮递员中的授权"标签设置为无身份验证"，我的标题"标签看起来像这样

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]

[服务器密钥]是Firebase项目设置"区域中云消息"选项卡中的新生成的服务器密钥.我不断收到此错误消息.

[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"
}

根据我能找到的所有内容，我使用的是正确的令牌，但Google似乎不同意.我应该发送什么作为Authorization标头来克服此错误?

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?

推荐答案

您必须在Postman中生成新的访问令牌.

You have to generate new access token in Postman.

首先，请确保您已在Google Developer Console中启用了FCM API. 比转到Google Developer Console-> APIs&服务->凭证.查看"OAuth 2.0客户端ID"部分.列表中至少应有一项.将其下载为json文件.

First, ensure you have enabled FCM API in Google Developer Console. Than go to Google Developer Console -> APIs & Services -> Credentials. Look at "OAuth 2.0 client IDs" section. There should be at least one item in list. Download it as json file.

在邮递员中打开授权"选项卡，选择类型" ="OAuth 2.0"，然后单击获取新访问令牌".出现对话框.

In Postman open "Authorization" tab, select Type = "OAuth 2.0" than click "Get New Access Token". Dialog appears.

字段:

令牌名称-输入您想要的

Token Name - type what you want

授予类型=授权代码

下载的json中的回调URL = redirect_uris

Callback URL = redirect_uris from downloaded json

验证URL = auth_uri

Auth URL = auth_uri

访问令牌URL = token_uri

Access Token URL = token_uri

客户ID = client_id

Client ID = client_id

Client Secret = client_secret

Client Secret = client_secret

Scope =" https://www.googleapis.com/auth/firebase.messaging"

状态-留空

客户端身份验证=默认，作为基本身份验证标头发送

Client Authentication = default, Send As Basic Auth Header

单击请求令牌"，仅此而已.

Click "Request Token" and that's it.
