Firebase Storage Admin错误：400无效的Bucket名称

Question

var functions = require('firebase-functions');
var admin = require("firebase-admin");
var serviceAccount = require('./my-app-bla-bla.json');

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: 'https://my-app.firebaseio.com',
  storageBucket: 'gs://my-app.appspot.com'
});

const st = admin.storage();

st.bucket("gs://my-app.appspot.com/old-listings/"+listingKey).create(function(error, bucket, apiResponse) {
    if (error) {
        console.log("Couldn't create an OldListing bucket: " + error.code);
        console.log(apiResponse);
    } else {
        console.log("Created OldListing bucket");
    }
});

Couldn't create an OldListing bucket: 400
{ error: 
   { errors: [ [Object] ],
     code: 400,
     message: 'Invalid bucket name: \'my-app.appspot.com/old-listings/SomeUniqueID\'' } }

admin.storage().bucket("my-app.appspot.com").exists(function(error, exists) {
    if (!error) {
        if (exists) {
            console.log("Top Bucket Exists");
        } else {
            console.log("Top Bucket Does Not Exist");
        }
    } else {
        console.log("Top Bucket Error " + error.code);
    }
});

admin.storage().bucket("my-app.appspot.com/listings").exists(function(error, exists) {
    if (!error) {
        if (exists) {
            console.log("Listings Bucket Exists");
        } else {
            console.log("Listings Bucket Does Not Exist");
        }
    } else {
        console.log("Listings Bucket Error " + error.code);
    }
});

Top Bucket Exists
Listing Bucket Error undefined

当然，我的firebase存储中已经有一个名为listings的文件夹。那么究竟为什么第二个桶会没有定义呢？

Answer 1

const st = admin.storage();
const bucket = st.bucket('name-of-your-bucket');
const file = bucket.file('name-of-your-file');
