使用node.js将文件上载到Firebase存储

Question

"use strict";

var firebase = require('firebase');

var config = {
    apiKey: "AIz...kBY",
    authDomain: "em....firebaseapp.com",
    databaseURL: "https://em....firebaseio.com",
    storageBucket: "em....appspot.com",
    messagingSenderId: "95...6"
};

firebase.initializeApp(config);

// Error: firebase.storage is undefined, so not a function
var storageRef = firebase.storage().ref();

var uploadTask = storageRef.child('images/octofez.png').put(file);

// Register three observers:
// 1. 'state_changed' observer, called any time the state changes
// 2. Error observer, called on failure
// 3. Completion observer, called on successful completion
uploadTask.on('state_changed', function(snapshot){
    ...
}, function(error) {
    console.error("Something nasty happened", error);
}, function() {
  var downloadURL = uploadTask.snapshot.downloadURL;
  console.log("Done. Enjoy.", downloadURL);
});

但事实证明，Firebase无法从服务器端上传文件，正如它在文档中明确说明的那样：

Firebase存储不包括在服务器端Firebase npm模块中。相反，您可以使用gcloud Node.js客户机。

$npm安装--保存GCloud

var gcloud = require('gcloud')({ ... }); var gcs = gcloud.storage();
var bucket = gcs.bucket('<your-firebase-storage-bucket>');

我的第二次尝试是使用GCloud库，就像文档中提到的：

var gcloud = require("gcloud");

// The following environment variables are set by app.yaml when running on GAE,
// but will need to be manually set when running locally.
// The storage client is used to communicate with Google Cloud Storage
var storage = gcloud.storage({
  projectId: "em...",
  keyFilename: 'auth.json'
});

storage.createBucket('octocats', function(err, bucket) {

    // Error: 403, accountDisabled
    // The account for the specified project has been disabled.

    // Create a new blob in the bucket and upload the file data.
    var blob = bucket.file("octofez.png");
    var blobStream = blob.createWriteStream();

    blobStream.on('error', function (err) {
        console.error(err);
    });

    blobStream.on('finish', function () {
        var publicUrl = `https://storage.googleapis.com/${bucket.name}/${blob.name}`;
        console.log(publicUrl);
    });

    fs.createReadStream("octofez.png").pipe(blobStream);
});

Answer 1

var gcloud = require('gcloud');

var storage = gcloud.storage({
  projectId: '<projectID>',
  keyFilename: 'service-account-credentials.json'
});

var bucket = storage.bucket('<projectID>.appspot.com');
