英文:
Logs return object not found in firebase storage but it exist in the firebase storage console?
问题
我收到了以下错误：
FirebaseError: Firebase Storage：对象 'Bakery/Bakery Cuisine' 不存在（storage/object-not-found）
但是我最后检查的时候：
[![输入图片说明][1]][1]
路径是存在的，而且我大约30分钟前刚上传了一个文件。那么为什么 Firebase 存储说它不存在呢？
我想要做的是：能够下载 ```paramKey``` 路径下所有 .txt 文件中的内容，然后将该内容显示给用户看。
代码：
const [toReadfb, setToReadDatafb] = useState([])
useEffect (() => {
const rfb = sRef(storage, paramKey)
const output = getDownloadURL(rfb)
.then(function (url) {
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function(event) {
var blob = xhr.response;
};
xhr.open('GET', url);
xhr.send();
});
setToReadDatafb(output)
}, [])
console.log(toReadfb)
来自 ```toReadfb``` 的日志：
{"_1": 0, "_2": 0, "_3": null, "_4": null}

I got the following error:
FirebaseError: Firebase Storage: Object 'Bakery/Bakery Cuisine' does not exist. (storage/object-not-found)
But last I checked:
The path is there and I just uploaded a file in like 30 mins ago. So how come firebase storage is saying it does not exist?
What I want to do: To be able to download the content insid all the .txt files under the path of paramKey and then display out that content for users to see.
Code:
const [toReadfb, setToReadDatafb] = useState([])
useEffect (() => {
const rfb = sRef(storage, paramKey)
const output = getDownloadURL(rfb)
.then(function (url) {
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function(event) {
var blob = xhr.response;
};
xhr.open('GET', url);
xhr.send();
});
setToReadDatafb(output)
}, [])
console.log(toReadfb)
My logs from toReadfb
{"_1": 0, "_2": 0, "_3": null, "_4": null}

Bakery/Bakery Cuisine在你的截图中是一个文件夹，不是一个文件。无法获取文件夹的下载URL。
Post60e...5ea在你的截图中是一个文件。如果你想获取该文件，你需要传递它的完整路径（如：Bakery/Bakery Cuisine/Post60e...5ea）。
如果你想获取文件夹中文件的列表，请查阅Firebase文档上关于列出文件的部分。
英文:
The Bakery/Bakery Cuisine in your screenshot is a folder, not a file. There is no way to retrieve the download URL of a folder.
The Post60e...5ea in your screenshot is a file. If you want to retrieve that file, you'll need to pass its entire path (so: Bakery/Bakery Cuisine/Post60e...5ea).
If you want to get a list of the files in a folder, have a look at the Firebae documentation on listing files.
