upload jpg file to Firebase Storage from Raspberry-Pi 3 using Node.js

[陳體平]

Hello,

I'd like to get your advice to solve below issue. 

Now I am working on a project to take photos with a Raspberry Pi 3(Model B) by its camera, and upload photo to firebase storage. My 1st step is to upload a JPG file from local folder as a test. I did it on my desktop PC and it looks working fine. I could check it on the firebase storage console. Then I deploy the file to Raspberry Pi and run the same node.js file again, see my My code below. It is interesting to find error message as below.

I understand it is necessary to find clues from Google Cloud Platform. According to advice from forum, I add the permission under "Storage Administration". See screen cut below. But it is not working. I got same error message when running again on RPi3.

I am exhausting to trial run it without clues. I appreciate a lot if some one can help solve it. 

A. Node.js file 

   

 const firebase = require('firebase');


    var config = {
 apiKey: "my_API-key",
 authDomain: "my_ProjID.firebaseapp.com",
 databaseURL: "https://my_ProjID.firebaseio.com",
 projectId: "my_ProjID",
 storageBucket: "my_ProjID.appspot.com",
 messagingSenderId: "12800393xxxx"
    };
   
    firebase.initializeApp(config);
 
 const storage = require('@google-cloud/storage')();
 var bucket = storage.bucket('my_ProjID.appspot.com');
 var db = firebase.database();
 var ref = db.ref("/test");
 
    bucket.upload("./images/jf.jpg", { destination: "images/1.jpg" }, (err, file) => {
 if (err) { return console.error(err); }
 let publicUrl = `https://firebasestorage.googleapis.com/v0/b/${config.projectId}.appspot.com/o/${file.metadata.name}?alt=media`;
 var data = {"URL": publicUrl };
 ref.set(data);
 });

Hello,

Any differences in the package.json files between your local machine and the Pi? That seems like a good starting point.

Note that I don't think the firebase-tools login is really what you want for use on your Pi devices. You do not want to deploy your service account credentials on those or use command line auth. 

Instead, you should be using the client node.js tools and implementing an appropriate authentication strategy for your clients. It's hard to guess what would work best for you here without knowing what the devices are and what capabilities they'll have (i.e. if you can make the user authenticate on the device or if you need a custom solution).

☼, Kato
