从Firebase商店获取图像列表 [英] Get list of images from Firebase Store

问题描述

我想获取图像列表，该图像是我在Web Firebase控制台中手动上传的.有什么方法可以不使用FirebaseRecyclerAdapter而获得所有文件的列表?

I want to get list of images which I uploaded manually in web Firebase console. Is there any way I can get list of all files without using FirebaseRecyclerAdapter?

推荐答案

没有现有的方法来提取您在Firestore中保存的文件名列表.相反，您必须使用一些解决方法来手动创建列表.例如，在Firebase数据库中维护文件和URL的列表.

There is no existing method to extract the list of file name you have saved in Firestore. Instead you have to use some workaround to manually create a list. For example, maintaining a list of file and URL inside Firebase database.

一种可能的解决方案是使用云功能编写触发器，侦听对Firebase Storage所做的更改.(由于这一次您直接通过控制台进行上传，因此您必须编写触发器并将其托管在云功能中) .在附件列表中进行插入/删除/修改后，更新firebase数据库中的虚拟文件条目.当您尝试提取文件/URL信息列表时，请从数据库而不是存储中检索它们.

One possible solution is to write a trigger using cloud functions, listening to the changes made to Firebase Storage.(as this time you are doing the upload directly through console, you have to write a trigger and host it in cloud function). Upon there is insertion/ removal/ modification in the attachment list, update the dummy file entries inside the firebase database. When you are trying to extract the list of file/ url information, retrieve them from database but not storage.
