  • Before using this API, make sure you understand the billing methods and pricing of Intelligent Media Management (IMM).

    Important The completion time of asynchronous tasks is not guaranteed.

  • File count limit: A compressed file can contain a maximum of 80,000 files.

  • File size limit: The maximum size is 200 GB for ZIP and RAR files, and 50 GB for 7z files.

  • This is an asynchronous API. Task information is saved for 7 days after a task starts and is then deleted. To view the task information, call the GetTask or ListTasks operation with the returned TaskId. You can also set the Notification parameter to receive task information through notification messages.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Leave this parameter empty if you do not have special requirements.

The configuration for chained authorization. This parameter is not required. For more information, see Use chained authorization to access resources of other entities.

Password

string

No

The password of the compressed file. If the file is encrypted, provide the password to inspect its contents.

123456

UserData

string

No

Custom information that is returned in the asynchronous notification message. You can use this information to associate the notification message with your services. The maximum length is 2,048 bytes.

test-data

SourceURI

string

No

The location of the compressed file.

The Object Storage Service (OSS) URI must be in the oss://${Bucket}/${Object} format. In this format, ${Bucket} is the name of the OSS bucket that is in the same region as the current project, and ${Object} is the full path of the file, including the file name extension.

oss://bucket/test-object.zip

Notification Notification

No

The notification configuration. For more information, see Notification. For the format of asynchronous notification messages, see Asynchronous notification message format.

Note

Currently, API callbacks in IMM do not support custom webhook addresses. Use MNS instead.

  • To retrieve the list of files in the compressed file, set the ExtendedMessageURI parameter in Notification. The generated file list is structured as follows:

{
  "Password" : "The password of the compressed file",
  "IsEncryption": "true/false, specifies whether the compressed file is encrypted",
  "ArchiveFiles": [
    {
      "PathName": "The path of the file relative to the compressed file. Example: ./test-dir/test.txt",
      "Reason": "If the inspection fails, the reason for the failure.",
      "IsFolder": "true/false, specifies whether the entry is a folder",
      "PackedSize": "The size of the file within the compressed file",
      "UnPackedSize": "The size of the file after decompression",
      "FileAccessTime": "The file access time.",
    },
    {
      "PathName": "./test-dir/",
      "Reason": "",
      "IsFolder": "true",
      "PackedSize": "0",
      "UnPackedSize": "0",
      "FileAccessTime": "2023-07-21T09:46:35Z",
    },
  ]
}
