将文件上传到特定目录中的Google Cloud

Question

如何在特定的存储桶目录(例如foo)中上传Google Cloud上的文件？

"use strict";

const gcloud = require("gcloud");

const PROJECT_ID = "<project-id>";

let storage = gcloud.storage({
  projectId: PROJECT_ID,
  keyFilename: 'auth.json'
});

let bucket = storage.bucket(`${PROJECT_ID}.appspot.com`)
bucket.upload("1.jpg", (err, file) => {
    if (err) { return console.error(err); }
    let publicUrl = `https://firebasestorage.googleapis.com/v0/b/${PROJECT_ID}.appspot.com/o/${file.metadata.name}?alt=media`;
    console.log(publicUrl);
});

我试过了:

bucket.file("foo/1.jpg").upload("1.jpg", ...)

但那里没有upload方法.

我1.jpg该如何发送foo目录？

在Firebase中,在客户端,我做:

ref.child("foo").put(myFile);

Answer 1

bucket.upload("1.jpg", { destination: "YOUR_FOLDER_NAME_HERE/1.jpg" }, (err, file) => {
    //Do something...
});

这将使1.jpg在YOUR_FOLDER_NAME_HERE-folder.

这是文档.顺便说一句,gcloud已被弃用,你应该使用谷歌云.

2020 年更新

根据谷歌文档：

const { Storage } = require('@google-cloud/storage');
const storage = new Storage()
const bucket = storage.bucket('YOUR_GCLOUD_STORAGE_BUCKET')
const blob = bucket.file('youFolder/' + 'youFileName.jpg')

const blobStream = blob.createWriteStream({
    resumable: false,
    gzip: true,
    public: true
})

blobStream.on('error', (err) => {
    console.log('Error blobStream: ',err)
});

blobStream.on('finish', () => {
// The public URL can be used to directly access the file via HTTP.
    const publicUrl = ('https://storage.googleapis.com/'+ bucket.name + '/' + blob.name)
    res.status(200).send(publicUrl);
});

blobStream.end(req.file.buffer)//req.file is your original file
