我想查看Cloud Firestores日志，就像看到Firebase的Cloud Functions一样.Firebase控制台的功能"选项卡中有一个日志"选项卡.同样，我想在Cloud Firestore中看到这一点.怎么样?

I want to see Cloud Firestores logs like I can see for Cloud Functions for Firebase. There is a logs tab in Functions tab of the Firebase console. Similarly I want to see this for Cloud Firestore. How?

推荐答案

我编写了一个Firebase云函数，用于将所有活动记录到Firestore:

I wrote a firebase cloud function to log all activity to Firestore:

/** * Logs all database activity * * @type {CloudFunction<Change<DocumentSnapshot>>} */ exports.dbLogger = functions.firestore .document('{collection}/{id}') .onWrite(async (change, context) => { const {collection, id} = context.params; if (collection !== 'firestore_log') { const event = context.eventType; const data = change.after.data(); const created_at = Date.now(); admin.firestore().collection('firestore_log').add({collection, id, event, data, created_at}); } });

这是记录的数据的示例:

Here's an example of the logged data:

请注意，这是一个仅记录所有内容的快速开发人员版本；在生产中，我们有Firestore规则来拒绝对表的任何读/写(firebase函数的管理员仍然可以访问它们):

Note that this is a quick dev only version that logs everything; in production we have Firestore rules to deny any read / write to the table (the admin on firebase functions can still access them):

// firestore.rules match /firestore_log/{entryId} { allow read: if false; allow write: if false; }

并过滤记录的集合，以避免持久保存敏感数据.

and filter the logged collections to avoid persisting sensitive data.

请注意，如果您希望将其保留在日志中而不是Firestore中，则可以使用 console.log({....}).我更喜欢Firestore，因为它旨在处理更大的数据集.

Note that if you prefer to persist this in the logs instead of Firestore you can use console.log({....}). I prefer Firestore because its designed to handle larger data sets.
