A SAS URI (Shared Access Signature Uniform Resource Identifier) in Azure Blob Storage consists of the following components:

Storage account name: This is the name of the Azure Storage account that the SAS URI belongs to.

Blob container name: This is the name of the blob container that the SAS URI is granting access to.

Blob name: This is the name of the specific blob within the container that the SAS URI is granting access to.

SAS token: This is the actual Shared Access Signature token that grants access to the resource. It includes an access policy and a signature that verifies the identity of the requester and the validity of the permissions being granted.

Here’s an example of a SAS URI for a blob in Azure Blob Storage:

https://mystorageaccount.blob.core.windows.net/mycontainer/myblob.txt?sv=2022-02-01&ss=b&srt=sco&sp=rwlac&se=2023-04-30T23:59:59Z&st=2023-04-01T00:00:00Z&spr=https&sig=mySASsignature

In this example, “mystorageaccount” is the name of the storage account, “mycontainer” is the name of the blob container, “myblob.txt” is the name of the blob being accessed, and the SAS token includes access policies and a signature.
