Table 2 Parameter description

Parameter

Description

Example Value

ak/sk

Specifies the AK/SK access key.

NOTE:
  • AK/SK generation description: Log in to the management console, choose My Credentials, and click Access Keys to create an AK and SK.
  • The time error between the AK/SK signature time and UTC time cannot exceed 15 minutes. Otherwise, the authentication fails.
  • If the AK/SK signature fails for more than five consecutive times, the AK/SK request of the source IP address is locked for 5 minutes.

N/A

project_id

Specifies the project ID. For details about how to obtain the project ID, see How Do I Obtain the IAM Username, Account ID, and Project ID?.

N/A
