Firebase 401未经授权的错误FCM [英] Firebase 401 unauthorized error FCM

问题描述

我正尝试测试Firebase Cloud消息传递API，因为控制台无法提供所有功能(尤其是在后台运行应用程序时自定义通知).但是由于某些原因，我无法使其正常工作，并且始终显示401错误.我调查了这种情况的原因，并在重新生成新的服务器密钥后进行了尝试，但是错误仍然保持不变.令人惊讶的是，当我生成新的服务器密钥时，它没有反映在Firebase控制台中，并且显示服务器密钥为空.另外，我尝试将我的IP地址添加到服务器白名单IP中，但还是没有运气.我已经附上了我对Postman所做的请求的屏幕截图(我用服务器密钥代替了 serverKey .

I'm trying to test out Firebase Cloud messaging APIs as all functionality is not available from console (notably customization of notifications when app is in background). But for some reasons, I cannot get it to work, and it always shows up 401 error. I investigated the reasons for this, and tried it after regenerating new server key, but the error remains constant. Surprisingly, when I generated a new server key, it is not reflected in Firebase console and it shows server key as empty. Also, I tried adding my IP address to the server whitelist IPs but still no luck. I've attached a screenshot of a request that I did with Postman (I substitue the server key in place of serverKey.

我在这个问题上待了几个小时，非常感谢您的帮助.

I'm stuck on this for a few hours and would really appreciate some help.

推荐答案

我从您的屏幕截图中注意到您正在使用"key:serverKey".您可以尝试改用"key = serverKey"吗?

I noticed from your screenshot that you were using "key: serverKey". Could you try using "key=serverKey" instead?

您也不需要"POST fcm.googleapus.com/fcm/send"；这是不正确的json，会解释您所看到的错误.该请求的URL已在其他位置定义，因此请将其从有效负载中删除.

Also you don't need to have "POST fcm.googleapus.com/fcm/send"; this is not proper json and would explain the error you are seeing. The URL of the request is already defined elsewhere so remove it from the payload.
