推荐答案
是说没有指定授权.确保在请求中包含Authorization:key=<Server API key here>，其中服务器密钥是您在Firebase控制台中 Cloud Messaing 选项卡下找到的密钥.
It's saying that there is no authorization specified. Make sure you're including the Authorization:key=<Server API key here> in your request, where the Server Key is the one found in your Firebase Console, under Cloud Messaing tab.
