【问题描述】：

是否有将 Azure 文件共享复制到 Blob 的示例（在 node.js 中）？ 服务器到服务器，无需事先下载文件。

提前致谢。

我的代码：

    var arrFolders = [];
    arrFolders.push("");
    do 
    
        let directoryName = arrFolders.pop();
        console.log(`List directories and files under directory $directoryName`);
        let i = 1;
        const directoryClient = shareClient.getDirectoryClient(directoryName);
        for await (const entity of directoryClient.listFilesAndDirectories()) 
        
            if (entity.kind === "directory") 
            
                console.log(`$i++ - directory\t: $entity.name`);
                arrFolders.push((directoryName=="") ? entity.name : directoryName + "\\" + entity.name);
             
            else 
            
                console.log(`$i++ - file\t: $entity.name`);
                // Copy Files to Blob....
                // ?????
                
            
        
        
     while (arrFolders.length > 0);
    console.log("End list directories and files");

如果您想将 Azure 文件复制到 Azure Blob，我们可以使用其余 API Copy Blob。

在node sdk中，我们可以使用@azure/storage-blob包中的BlobClient.beginCopyFromURL方法来实现。

例如

const  BlobServiceClient  = require("@azure/storage-blob");
const 
  ShareClient,
  generateAccountSASQueryParameters,
  StorageSharedKeyCredential,
  AccountSASResourceTypes,
  AccountSASPermissions,
  AccountSASServices,
 = require("@azure/storage-file-share");

const fileAccountName = "";
const fileAccountKey ="";

const blobConStr ="";

async function copy() 
  // create account sas token for file service
  var fileCreds = new StorageSharedKeyCredential(
    fileAccountName,
    fileAccountKey
  );
  var accountSas = generateAccountSASQueryParameters(
    
      startsOn: new Date(new Date().valueOf() - 8640),
      expiresOn: new Date(new Date().valueOf() + 86400000),
      resourceTypes: AccountSASResourceTypes.parse("sco").toString(),
      permissions: AccountSASPermissions.parse("rwdlc").toString(),
      services: AccountSASServices.parse("f").toString(),
    ,
    fileCreds
  ).toString();

  //get file share client
  var shareClient = new ShareClient(
    `https://$fileAccountName.file.core.windows.net/<shareName>`,
    fileCreds
  );
  //get blob container client
  var blobServiceClient = BlobServiceClient.fromConnectionString(blobConStr);
  var containerClient = blobServiceClient.getContainerClient("<containerName>");
  await containerClient.createIfNotExists();

  // list files and copy files to azure blob
  var arrFolders = [];
  arrFolders.push("input");
  do 
    let directoryName = arrFolders.pop();
    console.log(`List directories and files under directory $directoryName`);
    let i = 1;
    const directoryClient = shareClient.getDirectoryClient(directoryName);
    for await (const entity of directoryClient.listFilesAndDirectories()) 
      if (entity.kind === "directory") 
        console.log(`$i++ - directory\t: $entity.name`);
        arrFolders.push(
          directoryName == "" ? entity.name : directoryName + "\\" + entity.name
        );
       else 
        console.log(`$i++ - file\t: $entity.name`);
        var fileClient = directoryClient.getFileClient(entity.name);
        var soureUrl = fileClient.url + "?" + accountSas;
        try 
          var res = await (
            await containerClient
              .getBlobClient(entity.name)
              .beginCopyFromURL(soureUrl)
          ).pollUntilDone();
          console.log(res.copyStatus);
         catch (error) 
          throw error;
        
      
    
   while (arrFolders.length > 0);
