Management-Side SDK Management

You can deploy the management-side manager-node SDK locally, on cloud servers, or even in cloud functions to perform batch operations on files in cloud storage space, including upload, download, deletion, file information retrieval, temporary link acquisition, and file permission setting.

Upload files

Call the uploadFile method on the management side to upload a single file.

const CloudBase = require("@cloudbase/manager-node");

const path = require("path");

const { storage } = new CloudBase({
  secretId: "Your SecretId",
  secretKey: "Your SecretKey",
  envId: "Your envId" // CloudBase environment ID, can be obtained from the Tencent Cloud CloudBase console
});

async function uploadFile() {
  await storage.uploadFile({
    localPath: path.resolve("./data.txt"),
    cloudPath: "files/data.txt",
    onProgress: (data) => {}
  });
}

uploadFile();

Upload folders

Calling uploadDirectory on the management side enables batch uploading of files within a folder to cloud storage space.

const CloudBase = require("@cloudbase/manager-node");

const path = require("path");

const { storage } = new CloudBase({
  secretId: "Your SecretId",
  secretKey: "Your SecretKey",
  envId: "Your envId" // CloudBase environment ID, can be obtained from the Tencent Cloud CloudBase console
});

async function uploadDirectory() {
  await storage.uploadDirectory({
    localPath: path.resolve("./files"),
    cloudPath: "",
    onProgress: (data) => {}
  });
}

uploadDirectory();

Download files

Call the downloadFile method on the management side to download a single file.

const CloudBase = require("@cloudbase/manager-node");

const path = require("path");

const { storage } = new CloudBase({
  secretId: "Your SecretId",
  secretKey: "Your SecretKey",
  envId: "Your envId" // CloudBase environment ID, can be obtained from the Tencent Cloud CloudBase console
});

async function downloadFile() {
  await storage.downloadFile({
    cloudPath: "files/data.txt",
    localPath: path.resolve("./data.txt")
  });
}

downloadFile();

Download folders

Calling the downloadDirectory method on the management side enables downloading a specified folder from cloud storage space to a designated folder on the management side.

const CloudBase = require("@cloudbase/manager-node");

const path = require("path");

const { storage } = new CloudBase({
  secretId: "Your SecretId",
  secretKey: "Your SecretKey",
  envId: "Your envId" // CloudBase environment ID, can be obtained from the Tencent Cloud CloudBase console
});

async function downloadDirectory() {
  await storage.downloadDirectory({
    cloudPath: "files/music",
    localPath: path.resolve("./music")
  });
}

downloadDirectory();

Deleting Files

Call the deleteFile method on the management side to perform batch deletion of single or multiple files.

const CloudBase = require("@cloudbase/manager-node");

const { storage } = new CloudBase({
  secretId: "Your SecretId",
  secretKey: "Your SecretKey",
  envId: "Your envId" // CloudBase environment ID, can be obtained from the Tencent Cloud CloudBase console
});

async function deleteFile() {
  await storage.deleteFile(["files/data.txt", "uploads/logo.png"]);
}

deleteFile();

Delete folders

Calling the deleteDirectory method on the management side enables deletion of entire folders within cloud storage space.

const CloudBase = require("@cloudbase/manager-node");

const { storage } = new CloudBase({
  secretId: "Your SecretId",
  secretKey: "Your SecretKey",
  envId: "Your envId" // CloudBase environment ID, can be obtained from the Tencent Cloud CloudBase console
});

async function deleteDirectory() {
  await storage.deleteDirectory("files/");
}

deleteDirectory();

Getting File Information

Calling the getFileInfo method on the management side retrieves the file's size, type, modification time, and the entity tag (ETag) of the object.

const CloudBase = require("@cloudbase/manager-node");

const { storage } = new CloudBase({
  secretId: "Your SecretId",
  secretKey: "Your SecretKey",
  envId: "Your envId" // CloudBase environment ID, can be obtained from the Tencent Cloud CloudBase console
});

async function getFileInfo() {
  const info = await storage.getFileInfo("files/data.txt");
  console.log(info);
}

getFileInfo();

Listing Files in a Folder

Calling the listDirectoryFiles method on the management side lists all files and their information within the specified folder in cloud storage space.

const CloudBase = require("@cloudbase/manager-node");

const { storage } = new CloudBase({
  secretId: "Your SecretId",
  secretKey: "Your SecretKey",
  envId: "Your envId" // CloudBase environment ID, can be obtained from the Tencent Cloud CloudBase console
});

async function listDirectoryFiles() {
  const res1 = await storage.listDirectoryFiles("dir/data");

  const res2 = await storage.listDirectoryFiles("dir/data", 20);

  const res3 = await storage.listDirectoryFiles("dir/data", 20, "dir/dat");

  for (let item in res1) {
    console.log(item);
  }
}
listDirectoryFiles();
