Azure storage 'put block list' returns 400

Question

I'm trying to upload block blobs to Azure storage using SAS. I have successfully uploaded the blocks (validated by calling GET blocklist) but I can't get the PUT blocklist to work. I get "bad request 400" back.

The body is encoded using UTF8 (Swift):

body.dataUsingEncoding(NSUTF8StringEncoding)!

Here are the request and response:

BODY: "<?xml version=\"1.0\" encoding=\"utf-8\"?><BlockList><Latest>MDAwMDAw</Latest><Latest>MDAwMDAx</Latest></BlockList>"

Server Response: 400

}

Answer 1

As Zhaoxing has already mentioned, I also see that "sv=" is missing.
