list files and folders inside an azure DataLake storage Gen2 container using SAS at a directory level

I have a storage account which has the hierarchical namespace feature enabled (data lake storage gen 2) with the following file structure.

container/folder1/folder2/folder3/file1.txt container/folder1/folder2/folder3/file2.txt

I created a SAS token on the directory 2 level. Here is my generated URI

https://testtest123test.blob.core.windows.net/container/folder1/folder2/?sv=2024-11-04&se=2024-10-04T21%3A44%3A27Z&sr=d&sp=rl&sdd=2&sig=removed.

I want to list all the files and folders inside Folder 2.

I added "&restype=directory&comp=list" at the end of my URL ,but I got the following error :

<?xml version="1.0" encoding="utf-8"?>
<Error>
    <Code>InvalidQueryParameterValue</Code>
    <Message>Value for one of the query parameters specified in the request URI is invalid.

    <QueryParameterName>comp</QueryParameterName>
    <QueryParameterValue>list</QueryParameterValue>
</Error>

I also tried adding "&restype=container&comp=list" at the end of my URL, but I got the following error :

<?xml version="1.0" encoding="utf-8"?>
<Error>
    <Code>InvalidUri</Code>
    <Message>The requested URI does not represent any resource on the server.

</Error>

Can anyone help?

thanks

list files and folders inside an azure DataLake storage Gen2 container using SAS at a directory level.

You can use the below provided Rest API to list the second level of folder and files in Azure Data lake Storage Gen2.

In my environment, I created SAS token from directory level(folder2)through portal with rl(read and list) permission.

Portal:

Request:

https://<storage account name>.dfs.core.windows.net/<Conatiner name>?directory=folder1/folder2&recursive=true&resource=filesystem&sp=rl&st=2024-10-07T03:52:29Z&se=2024-10-07T11:52:29Z&spr=https&sv=2022-11-02&sr=d&sig=removed&sdd=2
