Google的Firebase Downstream消息的http发布请求中的Authorization部分是什么？ [英] What is the `Authorization` part of the http post request of Google's Firebase Downstream message?

问题描述

我想尝试使用google的 FCM 消息服务发送消息，正如文档所说，http请求应该是这样的：

  https://fcm.googleapis.com/fcm/send 
 Content-Type：application / json 
 Authorization：key = AIzaSyZ-1u ... 0GBYzPu7Udno5aA 
 
 {data：{
score：5x1，
time：15:10
 }，
to：bk3RNwTe3H0：CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1 ...
} 
  

<我的问题是我不知道什么 Authorization 的值应该是，当我删除这个头，并提出请求，我得到错误 401：未经授权。我认为这必须是某种API密钥或者某些东西，但我无法在我的项目中找到它。任何人都可以帮助我？

PS：为了测试目的，我目前使用

I want to try to send a message using google's FCM messaging service and as the document says, the http request should be something like this:

https://fcm.googleapis.com/fcm/send
Content-Type:application/json
Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA

{ "data": {
    "score": "5x1",
    "time": "15:10"
  },
  "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1..."
}

My problem is that I have not idea what Authorization's value should be and when I delete this header and make the request, I get error 401:Unauthorized.I think this must be some kind of api key or something but I cannot find it in my project. Can anyone help me?

PS: for testing purposes I currently am using this site to send a messsage to my device

解决方案

According to About Firebase Cloud Messaging Server documentation:

Authentication

To send a message, the app server issues a POST request. For example:

https://fcm.googleapis.com/fcm/send

A message request consists of two parts: the HTTP header and the HTTP body.

The HTTP header must contain the following headers:

• Authorization: key=YOUR_SERVER_KEY

  Make sure this is the server key, whose value is available in your Firebase project console under Project Settings > Cloud Messaging. Client keys or any other keys are rejected by FCM.

• Content-Type: application/json for JSON; application/x-www-form-urlencoded;charset=UTF-8 for plain text.

  If Content-Type is omitted, the format is assumed to be plain text.

Hope it helps!

UPDATE (2016/11/16)

Perhaps you should consider using the FCM token instead of the server keys as the note inside the following screenshot

UPDATE (2016/12/08)

Firebase has upgraded the server keys to a new version and recommended that you upgrade to the newest version. Please see the screenshot below:
