Storage Gen2 API in Postman

Question

Hi ,

I am new to Azure Portal and would like to use the Azure Gen2 API to create the files on storage.

I have been able to generate the access token in Postman -

https://login.microsoftonline.com/\<tenant id>/oauth2/v2.0/token

I now have access token to be used.

Now I call -

https://storageaccountshiv.dfs.core.windows.net/blue?resource=filesystem

Headers passed are -

Authorization : Bearer {access token}
x-ms-version : 2020-12-23
Content-Length : 0

But complains
{
"error": {
"code": "InvalidHeaderValue",
"message": "The value for one of the HTTP headers is not in the correct format.\nRequestId:34111c9a-d01f-0004-1787-d9cf50000000\nTime:2020-12-23T23:55:50.5175280Z"
}
}

I went through some posts and it says this is what we need to pass. Any idea what could be missing here.

This should create a folder under "Blob Containers".. Correct?

Thanks in advance.

Thanks,
Shiv

Hi Sumarigo,

Thanks for getting back to me. Much appreciated.

So, I followed the links you shared and generated the SAS (Shared access signature) token.

I used connection string URL from there and appended to my URL in Postman like -

https://storageaccountshiv.dfs.core.windows.net/shiv?resource=filesystem&BlobEndpoint=https://storageaccountshiv.blob.core.windows.net/;QueueEndpoint=https://storageaccountshiv.queue.core.windows.net/;FileEndpoint=https://storageaccountshiv.file.core.windows.net/;TableEndpoint=https://storageaccountshiv.table.core.windows.net/;SharedAccessSignature=sv=2019-12-12&ss=bfqt&srt=sco&sp=rwdlacupx&se=2020-12-26T01:52:21Z&st=2020-12-25T17:52:21Z&spr=https,http&sig=hNmiAsVfOKl5WUbgZCX00hFGCLtEOuafjuO2DDHsud%2Fg%3D

Also changed x-ms-version to 2020-04-08

I still get the error as -

{
"error": {
"code": "InvalidAuthenticationInfo",
"message": "Authentication information is not given in the correct format. Check the value of Authorization header.\nRequestId:5f03dfc0-001f-012b-54e8-da083f000000\nTime:2020-12-25T18:06:02.8681067Z"
}
}

Answer 3

Tried SAS token as well but still doesnt work -

https://storageaccountshiv.dfs.core.windows.net/shiv?resource=filesystem&?sv=2019-12-12&ss=bfqt&srt=sc&sp=rwdlacupx&se=2020-12-26T02:30:02Z&st=2020-12-25T18:30:02Z&spr=https,http&sig=uWCZjHJ7lVUeKByugrrEq6OCdV6QDguR9qOO%2FtlOg0w%3D

{
"error": {
"code": "InvalidAuthenticationInfo",
"message": "Authentication information is not given in the correct format. Check the value of Authorization header.\nRequestId:732c3822-201f-00dd-3eec-da697c000000\nTime:2020-12-25T18:31:52.6398753Z"
}
}

Hi Sumarigo,

Can we have a call for you to show me how this works.. This is little critical for us to get this going.

Thanks,

Hello, regarding the InvalidAuthenticationInfo error, please inspect the HTTP response www-authenticate header for more information about the error.
