Notification Description

This section provides an overview of the notification mechanism for file upload preprocessing tasks, such as when persistentOps instructions are included with the upload token.

Notification Security Mechanism

Object Storage will add an Authorization field to the notification’s request header.

Format

<Accesskey>:<Urlsafe_Base64_Encode(hmac_sha1(NotifyUrl+"\n"+Response,SecretKey))>

NOTE:

1. Response is the content of the notification received;
2. Object Storage will randomly pick any set of valid AK and SK under the user to generate the value of the authentication header Authorization. During the authentication process, you need to record all AK and SK sets and use one of the sets of correctly matched key strings to perform the header authentication.

Notification Data Description

After setting the notification address NotifyUrl, this address will obtain a URL-Safe Base64 Encoded Response message in JSON format. This message is simply the persistent processing result.
NOTE:
The address for receiving the preprocessing result notification must be a public network URL address that can respond normally with HTTP/1.1 200 OK. If there are special characters like spaces, Url Encode encoding is required.
