javascript - Firebase云功能1.0，当前用户没有身份验证信息

Question

我刚刚升级到 Firebase Cloud Functions 1.0，由于没有 event 参数，因此没有 event.auth.variable.uid 用于提供有关当前用户的信息(尽管没有记录)。

Firebase 1.0 有新的上下文参数，类似于

{ service: 'firebaseio.com',
 name: 'projects/_/<ref>/pushId5' },
 authType: 'ADMIN',
 params: { pushId: 'pushId5' } }

如何在新的 Firebase 函数 sdk 中获取当前用户信息？

根据文档:

EventContext.auth V1.0.0 introduces two new properties for accessing user information, including permissions, for the user that triggered a function.

EventContext.auth Contains information such as uid and the authenticated user's auth token.

EventContext.authType Contains permissions levels, allowing you to detect whether the user is an admin user, for example.

使用未记录的 event.auth 字段的开发人员应更新所有相关代码以使用这些新属性。

因此，要获取有关用户的信息，请执行以下操作:

exports.dbWrite = functions.database.ref('/path/with/{id}').onWrite((data, context) => {
const authVar = context.auth.uid;
const authType = context.authType.ADMIN;

});
