Firebase Cloud Storage下载URL与路径 [英] Firebase Cloud Storage download url vs path

问题描述

我是Firebase存储的新手，想知道什么是最佳实践. 我想将图像上传到Firebase云存储，并返回一个下载URL，然后将其存储到Firestore.下载网址是永久的吗?其他用户将从Firestore中读取以获取下载图片的网址.

I'm new to firebase storage and wants to know what is the best practice. I want to upload image to firebase cloud storage and was returned a download url which I then stored to firestore. Is the download url permanent? Other users will read from the firestore to get the url to download the image.

但是，当我想从CloudStorage删除映像时，我只有下载URL，而没有文件路径.那我要删除它吗?

But when I want to delete the image from CloudStorage, I only have the download url but not the file path. So do I delete it ?

如果我改为存储文件路径，如何获取下载网址?

If I store the file path instead, how to get the download url ?
