FirebaseStorage：如何删除目录 [英] FirebaseStorage: How to Delete Directory

问题描述

当我尝试删除目录时，FirebaseStorage始终返回错误 400 ，例如以下内容始终返回错误 400 。

FirebaseStorage always returns error 400 when I try to delete a directory i.e. something like the following always returns error 400.

let storageRef = FIRStorage.storage().reference().child("path/to/directory")
storageRef.deleteWithCompletion { (error) in
    print("error: \(error)") // always prints error code 400
}

然而，删除文件工作正常，例如类似的东西不会返回错误：

However, deleting a file works fine e.g. something like doesn't return an error:

let storageRef = FIRStorage.storage().reference().child("path/to/file.jpg")
storageRef.deleteWithCompletion { (error) in
    print("error: \(error)") // works fine, error is nil
}

我在这里做错了什么？我不认为它不受FirebaseStorage的支持，因为从目录中逐个删除文件会非常蹩脚（特别是如果所述目录有100或1000个这些）。

What could I be doing wrong here? I don't reckon it's not supported by FirebaseStorage because deleting files from a directory one by one would be pretty lame (specially if the said directory has 100s or 1000s of these).

推荐答案

，无法删除目录。您必须在某处保存文件列表（在Firebase数据库中）并逐个删除它们。

from google group, deleting a directory is not possible. You have to maintain a list of files somewhere (in Firebase Database) and delete them one by one.

我还提交了功能请求，但由于他们的错误跟踪器不公开，因此没有可以分享的链接。

I have also submitted the feature request but since their bug tracker isn't public, there's no link that I could share.
