Firebase storage don't return downloadURL

Question

I am using this code to update an image and get the URL, but I can´t get the URL back.

It seems that return some because it can enter in the return of the promise.

I get this code from here: https://gist.github.com/CristalT/2651023cfa2f36cddd119fd979581893

The code work for another user so I this the problems would be in the dependence or in the database rules.

I am authenticated.

    <template>

      <div>
        <input type="file" multiple accept="image/*" @change="detectFiles($event.target.files)">
        <div class="progress-bar" :style="{ width: progressUpload + '%'}">{{ progressUpload }}%</div>
      </div>

    </template>

    <script>
    import { storage } from '../firebase'
    export default {
      data () {
        return {
          progressUpload: 0,
          file: File,
          uploadTask: '',
          downloadURL: ''
        }
      },
      methods: {
        detectFiles (fileList) {
          Array.from(Array(fileList.length).keys()).map( x => {
            this.upload(fileList[x])
          })
        },
        upload (file) {
          this.uploadTask = storage.ref('imagenes/articulos').put(file);
          this.uploadTask.then(snapshot => {
            this.downloadURL = this.uploadTask.snapshot.downloadURL;
            this.$emit('url', this.downloadURL)
          })
        }
      },
      watch: {
        uploadTask: function() {
          this.uploadTask.on('state_changed', sp => {
            this.progressUpload = Math.floor(sp.bytesTransferred / sp.totalBytes * 100)
          })
        }
      }
    }
    </script>

    <style>
    .progress-bar {
      margin: 10px 0;
    }
    </style>

this is my package.json:

  ]
}

this are the storage rules:

 service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if request.auth != null;
    }
  }
}

this is my firebase.js: import Firebase from 'firebase'

/**
 * Pega aquí los datos de tu proyecto firebase
 */
const firebaseApp = Firebase.initializeApp({
  apiKey: "++++******-sU0qfey9278aBIDP6zo",
  authDomain: "*+****+.firebaseapp.com",
  databaseURL: "https://*****.firebaseio.com",
  projectId: "+++++",
  storageBucket: "**.appspot.com",
  messagingSenderId: "**"
  });

export const db = firebaseApp.database()
export const storage = firebaseApp.storage()
export const auth = firebaseApp.auth()
// export const notif = firebase.messaging()

in the terminal this is what I get:

$route
downloadURL:"" --->here shoud get the URL
file:ƒ File()
progressUpload:100
uploadTask:Object
authWrapper_:Object
blob_:Object
chunkMultiplier_:1
errorHandler_:ƒ (error)
error_:null
location_:Object
mappings_:Array[15]
metadataErrorHandler_:ƒ (error)
metadata_:Object

Thank so much in advance

Answer 1

i had the same problem, i tried a lot of stuff, but the simply one solution i found was:

---

to change the Firebase versión in my package.json i switched to: "firebase": "^4.6.2".

---

I am not sure what's happening with the 5.0.2 version. Even when that solve the problem i am still looking for the docs of the change maybe we need to use the snapshot in a different way. will see. Good luck! ;)

Update:

The issue is that the snapshop no longer own the downloadURL at version 5, now you have tu use the method getDownloadURL that belongs to the ref, just like pushups said, something like this:

const fileRef = firebase.storage()
    .ref("carpeta")
    .child(file.name);

const uploadTask = fileRef.put(file);

uploadTask
    .then(snap=>{
      return fileRef.getDownloadURL()
    })

this also works: return snap.ref.getDownloadURL()
