You can share files with other users temporarily or permanently.

Objects in the Archive or Deep Archive storage class can be shared only after they have been restored.
An authorization code is not required for temporarily sharing a file. Temporarily sharing a folder requires an authorization code when the method of sharing by access code is used. For details, see Sharing a Folder.
Only buckets of version 3.0 or later support temporary file sharing. For details about how to query the bucket version, see Checking OBS Version (OBS 2.0 or OBS 3.0).

The following table describes the URL validity period of the files that are temporarily shared using different tools.

Tool	URL Validity Period
OBS Console	The URL is valid for 1 minute to 18 hours. After an object is shared, the system will generate a URL that contains the temporary authentication information, valid for five minutes since its generation by default. Each time you change the validity period of a URL, OBS obtains the authentication information again to generate a new URL for sharing. The new URL becomes valid at the moment the validity period is changed.
SDKs	Configure parameter Expires to specify when a temporary authorization expires. The temporary authorization expires in 24 hours.
API	Configure parameter Expires to specify when a temporary authorization expires. The temporary authorization expires in 24 hours.
OBS Browser+	When you log in to OBS Browser+ using an account and password, a shared URL can be valid for 24 hours at most. The default validity period is 10 hours. If a longer validity period is required, use the permanent AK/SK for login.
obsutil	Use the additional parameter e to specify when an object download URL expires. The minimum value is 60s and the default one is 300s. There is no upper limit on the expiration time.

You can use OBS Console, SDKs, OBS Browser+, APIs, or obsutil to share files.

Tool	Reference
OBS Console	Sharing a File
SDKs	OBS supports software development kits (SDKs) in multiple languages. For details, see the corresponding developer guide on the SDK Overview page.
API	Authentication of Signature in a URL
OBS Browser+	Sharing a File or Folder
obsutil	Generating the Download Link of an Object

To download a generated temporary URL with wget, use "" and -O to specify the file name, or an error will occur.

Example:

[root@ecs-test ~]# wget "Temporary URL" -O abc

In the preceding command, abc indicates a new file name.
