无法从 Firebase 集合中删除文件

Question

我遵循here 列出的示例，但由于新firebase-tools 的API 有所修改。

exports.clearMessages = functions.runWith({ timeoutSeconds: 540, memory: '2GB' }).https.onCall(messagesController.clearMessages)

export const clearMessages = async (data, context) => {
    const uid = context.auth.uid
    const path = `users/${uid}/messages`
    return firebase_tools.firestore.delete('flightApp3', path, {
        recursive: true,
        shallow: true,
        allCollections: true
    }).then(result => {
        console.log('delete result', result)
        return result
    })
}

但是，当我运行它时，我看到 Cloud Functions 日志中显示以下内容：

Unhandled error { Error
    at Error.FirebaseError (/user_code/node_modules/firebase-tools/lib/error.js:9:18)
    at module.exports (/user_code/node_modules/firebase-tools/lib/getProjectId.js:10:19)

  children: [],

  exit: 1,

  original: undefined,
  context: undefined }

但是，我很确定我的 firebase CLI 中有一个活动项目。

$ firebase use
Active Project: production (flightApp3)

Project aliases for /Users/myUser/Developer/flightApp3/cloud:

* default (flightApp3)
* production (flightApp3)

Run firebase use --add to define a new project alias.

有些选项不能混用...

return firebase_tools.firestore.delete('flightApp3', path, {
    // allCollections: true,
    recursive: true,
    yes: true
}).then(() => {
    return {
      path: path 
    };
});

这就是构建路径的方式（path 和 allCollections 似乎也没有意义）：projects/${project}/databases/(default)/documents/users/${uid}/messages

getProjectId.js 检查rc.projects（其中options.project 是选项--project）：

module.exports = function(options, allowNull) {
    if (!options.project && !allowNull) {
        var aliases = _.get(options, "rc.projects", {});
        ...

这些rc.projects 是来自.firebaserc 文件的projects：

{
   "projects": {
        "default": "flightApp3"
    }
}

或运行firebase use default 以从别名production 切换到default（或删除别名production 一次以进行测试）。 FirestoreDelete(project, path, options) 也不再关心options.token 和options.project（正如documentation 所建议的那样）。

$ firebase firestore:delete --help 解释命令行选项：

Usage: firestore:delete [options] [path]

Delete data from Cloud Firestore.

Options:

  -r, --recursive    Recursive. Delete all documents and sub-collections. 
                     Any action which would result in the deletion of child
                     documents will fail if this argument is not passed.

                     May not be passed along with --shallow.


  --shallow          Shallow. Delete only parent documents and ignore documents
                     in sub-collections. Any action which would orphan documents
                     will fail if this argument is not passed.

                     May not be passed along with --recursive.


  --all-collections  Delete all. Deletes the entire Firestore database,
                     including all collections and documents.

                     Any other flags or arguments will be ignored.


  -y, --yes          No confirmation. Otherwise, a confirmation prompt will appear.

npm package（上面的输出）的版本是6.0.1。

刚刚找到一条相关评论（但可能已过时）：

token 必须在函数配置中设置，并且可以在命令行通过运行firebase login:ci 生成。

这提示environment configuration，因此functions.config().fb.token 具有token：

firebase functions:config:set fb.token="THE TOKEN"

也可以从process.env.FIREBASE_CONFIG.projectId获取projectId。

文档https://firebase.google.com/docs/firestore/solutions/delete-collections

在/functions目录下安装firebase-tools

    "firebase-tools": "^7.16.2"

在云函数中导入firebase-tools并调用delete

const firebaseTools = require("firebase-tools");
...
firebaseTools.firestore.delete(workspaceRef.path, {
                project: process.env.GCLOUD_PROJECT, // required
                recursive: true, // required
                yes: true // required
              })

从云函数调用firebase-tools 时不需要令牌。

此外，API https://github.com/firebase/firebase-tools/blob/v7.16.2/src/firestore/delete.js 的链接以及 FirestoreDelete 的代码实现似乎是错误的。

我已成功调用.delete(path, options)，但代码显示.delete(project, path, options)？
