Overview

You can upload objects on the Objects page of buckets via COS Console. For more information on objects, see Object Overview.

Directions

1. Entering the Objects

Log in to the COS Console. Click Bucket List, and select the bucket to store objects to enter the bucket's Objects page. Click Upload Files and the Upload Files window pops up as shown below.

2. Selecting the Object(s) to Upload

On the Upload Files page, click Select Files or Select Folders to upload a single or multiple local files/folders. After selecting the objects to upload locally, click Upload to upload the objects, or click Next to set the object attributes before uploading (see Step 3).

3. Setting Object Attributes (Optional)

Set the storage class, access permissions, server-side encryption and metadata (optional) for the files to upload, and then click Upload. The configuration items are described as follows:

  • Storage Class
    You can set a storage class for each object based on the use case. The default storage class is COS Standard. For more information on storage classes, see Storage Classes.
  • Access Permissions
    You can set access permissions for each object as needed. Default is "Inherit Permissions" (inherit permissions from bucket). For more information on access permissions, see Basic Concepts of Access Control.
  • Server-side Encryption
    You can configure server-side encryption for the objects you want to upload. Tencent Cloud COS will apply data encryption protection to the uploaded objects, so as to automatically encrypt data before it is written, and automatically decrypt the data when you access it. Tencent Cloud COS supports AES-256 encryption of data using the master key. For more information, see Server-side Encryption Overview.
  • Metadata
    The object metadata, or HTTP Header, is a string sent by the server over HTTP protocol before it sends HTML data to browser. By modifying the HTTP Header, you can change the response form of the page or communicate configuration information, such as modifying the caching time. Modifying an object's HTTP Header does not modify the object itself. For more information, see Custom Object Headers.
    After an object is uploaded successfully, the system automatically refreshes the list to get the latest object information, as shown below.

Some browsers do not support uploading multiple files. It is recommended to use mainstream browsers such as IE10 or above, Firefox, or Chrome.

4. Verifying the Completion of Upload

After clicking Upload, you can check the upload progress in Task completed in the top right of the page. After the upload is completed, you can see the uploaded object in the Objectspage of the bucket.
