Content-Length validation

[carl-sauter]

Hello there, I noticed that a Content-Length header is required for creating a container. This validation is not included in azurite and will only happen on a "real" blob storage.

This is the api I am talking about:
https://learn.microsoft.com/en-us/rest/api/storageservices/create-container?tabs=microsoft-entra-id

Although the request has no body, a real blobstorage returns 411 Length Required when the Content-Length: 0 header is not present. Azurite is fine without the header.

Maybe consider adding this validation also to azurite to keep it at close as possible to a real storage.

Would you please help to follow up?

From https://learn.microsoft.com/en-us/rest/api/storageservices/create-container?tabs=microsoft-entra-id, not see Content-Length is required header in rest API doc.
BTW, the storage swagger also not has Content-Length in create container API: https://github.com/Azure/azure-rest-api-specs/blob/efa49a123da7ce3ffe093a13832258305f529711/specification/storage/data-plane/Microsoft.BlobStorage/stable/2026-02-06/blob.json#L708

Azurite API is generated from the swagger, so it will be quite difficult to add this check before this header is include in doc/swagger.

If this is required header, would you please contact the swagger/rest API doc owner to add this header first, then we can try to add this to Azurite.

@blueww Thank you for your response. I was also surprised that it isn't mentioned in the docs. Because of this (and following, that azurite hasn't this check), the bug appeared in prod the first time. I will open an issue at the rest api repo.
