Host must be a SignedHeader about awssigner HOT 2 CLOSED

A little late on this one, but were you able to figure it out? I also fixed the error message you were getting. The extension was trying to send the request twice.

from awssigner.

thanks for great work!
this is fixed for me by providing signeheaders, example:

GET /?Param1=value1 HTTP/1.1
Host:example.amazonaws.com
Content-Type: application/x-www-form-urlencoded; charset=utf-8
X-Amz-Date:20150830T123600Z
Authorization: AWS4-HMAC-SHA256 Credential=AKIAIOSFODNN7EXAMPLE/20190101/us-west-1/test/request, SignedHeaders=content-type;host;x-amz-date, Signature=e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

from awssigner.
