解决方案
 
 
I'm trying to delete a blob in azure storage but my curl keeps returning the error below
<?xml version="1.0" encoding="utf-8"?><Error><Code>AuthenticationFailed</Code><Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.
RequestId:XX
Time:2018-08-09T10:09:41.3394688Z</Message><AuthenticationErrorDetail>The MAC signature found in the HTTP request 'xxx' is not the same as any computed signature. Server used following string to sign: 'DELETE'
This is my code
# Delete a blobs in an Azure storage container.

echo "usage: ${0##*/} <storage-account-name> <container-name> <access-key>"

storage_account="$1"
container_name="$2"
access_key="$3"

blob_store_url="blob.core.windows.net"
authorization="SharedKey"

request_method="DELETE"
request_date=$(TZ=GMT LC_ALL=en_US.utf8 date "+%a, %d %h %Y %H:%M:%S %Z")
#request_date="Mon, 18 Apr 2016 05:16:09 GMT"
storage_service_version="2018-03-28"

# HTTP Request headers
x_ms_date_h="x-ms-date:$request_date"
x_ms_version_h="x-ms-version:$storage_service_version"

# Build the signature string
canonicalized_headers="${x_ms_date_h}\n${x_ms_version_h}"
canonicalized_resource="/${storage_account}/${container_name}"

string_to_sign="${request_method}\n\n\n\n\n\n\n\n\n\n\n\n${canonicalized_headers}\n${canonicalized_resource}\ncomp:list\nrestype:container"


# Decode the Base64 encoded access key, convert to Hex.
decoded_hex_key="$(echo -n $access_key | base64 -d -w0 | xxd -p -c256)"


# Create the HMAC signature for the Authorization header
signature=$(printf "$string_to_sign" | openssl dgst -sha256 -mac HMAC -macopt "hexkey:$decoded_hex_key" -binary |  base64 -w0)

authorization_header="Authorization: $authorization $storage_account:$signature"

curl \
  -H "$x_ms_date_h" \
  -H "$x_ms_version_h" \
  -H "$authorization_header" \
  -H "Content-Length: 0"\
   X DELETE
  "https://${storage_account}.${blob_store_url}/${container_name}/somefolder/myfile.csv_123"
