Configuring Direct Reading for Archive Storage Objects in a Bucket

Function

Direct reading means that you can directly perform operations on Archive Storage objects without restoring them.

By default, direct reading is disabled for Archive Storage objects in a bucket.

This API is used to enable or disable direct reading for Archive Storage objects in a bucket.

  • When direct reading is enabled for Archive Storage objects in a bucket:
    • You can directly perform operations on Archive Storage objects in the bucket regardless of whether they have been restored.
    • If Archive Storage objects are not restored, your operations on them will be charged separately.
  • When direct reading is disabled for Archive Storage objects in a bucket:
    • You need to restore objects in the bucket before you can operate them.

Direct reading means that you can directly perform operations on objects without restoring them. For more information about direct reading of Archive Storage data, see Direct Reading.

Sample Code

This example sets the direct reading status for Archive Storage objects in bucket examplebucket.

    "fmt"


    "os"
)

    // Obtain an AK/SK pair using environment variables or import an AK/SK pair in other ways. Using hard coding may result in leakage.
    // Obtain an AK/SK pair on the management console.
    ak := os.Getenv("AccessKeyID")
    sk := os.Getenv("SecretAccessKey")
    // (Optional) If you use a temporary AK/SK pair and a security token to access OBS, you are not advised to use hard coding, which may result in information leakage. You can obtain an AK/SK pair using environment variables or import an AK/SK pair in other ways.
    securityToken := os.Getenv("SecurityToken")


    // Enter the endpoint corresponding to the bucket. CN-Hong Kong is used here as an example. Replace it with the one currently in use.
    endPoint := "https://obs.ap-southeast-1.myhuaweicloud.com"




    // Create an obsClient instance.
    // If you use a temporary AK/SK pair and a security token to access OBS, use the obs.WithSecurityToken method to specify a security token when creating an instance.
