Unable to create a blob in a container in Azure storage account using Shared Access Token

Question

Hi,

Describing in a few steps the issue:

1. I have a container in storage account and I am trying to upload a blob (create a new blob altogether) in that container via REST API.
2. I decided to use SAS URL that is available on the left pane of a container where we list the permissions and the allowed protocols etc. Lets say the SAS URL generated looked like (test being the container name): https://<myaccountname>.blob.core.windows.net/test/?sp=racwdli&st=2024-08-06T16:33:48Z&se=2024-08-07T17:00:48Z&spr=https&sv=2022-11-02&sr=c&sig=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
3. Later through some searching I found that two query parameters also need to appended, so the whole URL looks like https://<myaccountname>.blob.core.windows.net/test/?sp=racwdli&st=2024-08-06T16:33:48Z&se=2024-08-06T17:00:48Z&spr=https&sv=2022-11-02&sr=c&sig=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&comp=list&restype=container
4. Now I am using Postman to PUT a file at this URL using PUT method, however I keep getting the below error:

<Code>UnsupportedHttpVerb</Code>
    <Message>The resource doesn&apos;t support specified Http Verb.

Is there something I am missing or is this method not the right way to go about creating a new blob using REST API?

Hi,

Looks like the url to be corrected as below: In your url, the blob name is missing. Add the name like below and try again

https://<myaccountname>.blob.core.windows.net/test/<filename eg: test.txt>?sp=racwdli&st=2024-08-06T16:33:48Z&se=2024-08-07T17:00:48Z&spr=https&sv=2022-11-02&sr=c&sig=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Hope this helps.

Hello Priyal Sobti,

Greetings! Welcome to Microsoft Q&A Platform.

I understand that you are encountering a 405 error with the message "UnsupportedHttpVerb" ,“The resource doesn’t support specified HTTP Verb,” it indicates that the HTTP method you’re using is not allowed for the specific resource.

Ensure that you are using the correct HTTP verb for the operation. For Azure Blob storage, the supported HTTP verbs are typically PUT (for creating or updating messages) and GET (for retrieving messages) and also check some of the below resources that prove helpful to resolve your issue:

• https://developer.mozilla.org/en-US/docs/web/http/status/405
• https://learn.microsoft.com/en-us/rest/api/storageservices/http-operations-on-blob-service-resources
• https://learn.microsoft.com/en-us/troubleshoot/developer/webapps/iis/health-diagnostic-performance/http-error-405-website

Make sure your SAS token includes the necessary permissions for uploading a blob. For uploading, you need at least w (write) and c (create) permissions.

Double-check the URL you’re using. It should be in the format:

https://<myaccountname>.blob.core.windows.net/test/<blobname>?sp=racwdli&st=2024-08-06t16:33:48z&se=2024-08-07t17:00:48z&spr=https&sv=2022-11-02&sr=c&sig=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Ensure you have the correct headers set in your request, also please check your blob storage “Firewalls and virtual networks”. If Selected networks is checked, please try checking All networks. If you want to enable firewall, then please make sure to whitelist the IP's that need to access your storage account and let us know if it helps.
