I have been trying to update the metadata to my BlockBlob using Insomnia.I have managed to clear the metadata using the header(param json is empty):
with the strToSign:
"PUT\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:Fri, 11 Mar 2022 09:24:07 GMT\nx-ms-version:2021-04-10\n/myaccount/search/file_6444\ncomp:metadata"
but if I want to update the metadata, sending x-ms-meta-ide:2021 in the header(param json is empty), it doesn't work, it returns the error: AuthenticationErrorDetail The MAC signature found in the HTTP request 'XXXXXXXXX' is not the same as any computed signature.
The strToSign is:
"PUT\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:Fri, 11 Mar 2022 09:24:07 GMT\nx-ms-version:2021-04-10\nx-ms-meta-ide:2021\n/myaccount/search/file_6444\ncomp:metadata"
why it's not working?? Thanksss
Please change your string to sign to:
PUT\n\n\n\n\n\n\n\n\n\n\n\nx-ms-date:Fri, 11 Mar 2022 09:24:07 GMT\nx-ms-meta-ide:2021\nx-ms-version:2021-04-10\n/myaccount/search/file_6444\ncomp:metadata
Essentially the issue is that the headers must be alphabetically sorted in the string to sign so the order of the headers would be x-ms-date, x-ms-meta-ide and then x-ms-version.
