使用Nodejs将文件从Azure存储blob(容器)复制到Azure文件共享

Question

是否有方法将文件从Azure容器(Blob(复制到Azure文件共享？

我能够将文件从一个容器复制到另一个容器-见下文
但我想将文件从Blob复制到文件共享

const {
BlobServiceClient,
StorageSharedKeyCredential
} = require("@azure/storage-blob");
async function copy() {
const account = "<account-name>";
const accountKey = "<account-key>";
const cert = new StorageSharedKeyCredential(account, accountKey)
const blobServiceClient = new BlobServiceClient(
`https://${account}.blob.core.windows.net`,
cert
);
const sourceContainer = blobServiceClient.getContainerClient("documents")
const desContainer = blobServiceClient.getContainerClient("copy")
//if the desContainer does not exist, please run the following code
// await desContainer.create()
//copy blob
const sourceBlob = sourceContainer.getBlobClient("file1.png");
console.log(sourceBlob, sourceBlob.name)
const desBlob = desContainer.getBlobClient(sourceBlob.name)
const response = await desBlob.beginCopyFromURL(sourceBlob.url);
const result = (await response.pollUntilDone())
console.log(result._response.status)
console.log(result.copyStatus)
}
copy()

我已经在我的环境中进行了测试。

要将文件从Azure文件共享复制到Azure Blob存储，您可以使用以下代码：

const {
BlobServiceClient,
StorageSharedKeyCredential,
} = require("@azure/storage-blob");
const {
ShareServiceClient
} = require("@azure/storage-file-share")
async function copy() {
const account = "<account-name>";
const accountKey = "<account-key>";
const cert = new StorageSharedKeyCredential(account, accountKey)
const accountSas = "<account-sas>"
const blobServiceClient = new BlobServiceClient(
`https://${account}.blob.core.windows.net`,
cert
);
const serviceClient = new ShareServiceClient(`https://${account}.file.core.windows.net${accountSas}`,cert)
const sourceContainer = blobServiceClient.getContainerClient("containerName")
const shareClient = serviceClient.getShareClient("fileShareName")
const directoryClient = shareClient.getDirectoryClient("directoryName");
var fileClient = directoryClient.getFileClient("fileName");
//if the desContainer does not exist, please run the following code
// await desContainer.create()
//copy blob
const sourceBlob = sourceContainer.getBlobClient("blobFileName");
const response = await sourceBlob.beginCopyFromURL(fileClient.url);
}
copy()

要将文件从Azure Blob存储复制到Azure文件共享，我们可以先将Blob文件下载到本地，然后将本地文件上载到Azure文件分享。

您可以使用以下代码将blob文件下载到本地：

const {
BlobServiceClient,
StorageSharedKeyCredential,
} = require("@azure/storage-blob");
const account = "<account-name>";
const accountKey = "<account-key>";
const cert = new StorageSharedKeyCredential(account, accountKey)
const accountSas = "<account-sas>"

function download() {
const account = "<account-name>";
const accountKey = "<account-key>";
const cert = new StorageSharedKeyCredential(account, accountKey)
const accountSas = "<account-sas>"
const container = "containerName"
const blobFileName = "blobFileName"
const blobServiceClient = new BlobServiceClient(
`https://${account}.blob.core.windows.net`,
cert
);
const sourceContainer = blobServiceClient.getContainerClient(container)
const sourceBlob = sourceContainer.getBlobClient(blobFileName);
sourceBlob.downloadToFile(blobFileName);
}
download()

您可以使用以下代码将文件从本地上传到Azure文件共享：

const {
ShareServiceClient
} = require("@azure/storage-file-share");
function upload() {
const account = "<account-name>";
const accountKey = "<account-key>";
const cert = new StorageSharedKeyCredential(account, accountKey)
const accountSas = "<account-sas>"
const serviceClient = new ShareServiceClient(`https://${account}.file.core.windows.net${accountSas}`,cert)
const shareClient = serviceClient.getShareClient("fileShareName")
const directoryClient = shareClient.getDirectoryClient("directoryName");
var fileClient = directoryClient.getFileClient("FileName");
fileClient.uploadFile("localFilePath");
}
upload()
