Changed part in Step 2: Generate authentication parameters of Authentication, including the following updates:
Removed part secret_key from the composition of request_path.
Replaced the SHA256 signature method with HMAC-SHA256 signature, where 'secret_key' is used as the key.
The new feature is temporarily compatible with the old signature method. Please use the new signature method as soon as possible. The old signature method will be removed at a later date.
