Simple lua resty utilities to generate amazon v4 authorization and signature headers.
Openresty installation should be compiled with --with-luajit directive otherwise you will get an error,
module 'ffi' not found
Install the package using luarocks
#luarocks install lua-resty-aws-authlocal aws_auth = require "resty.aws-auth"
local config = {
aws_host = "email.us-east-1.amazonaws.com",
aws_key = "AKIDEXAMPLE",
aws_secret = "xxxsecret",
aws_region = "us-east-1",
aws_service = "ses",
content_type = "application/x-www-form-urlencoded",
request_method = "POST",
request_path = "/",
request_body = { hello="world" } -- table of all request params
}
local aws = aws_auth:new(config)
-- get the generated authorization header
-- eg: AWS4-HMAC-SHA256 Credential=AKIDEXAMPLE/20150830/us-east-1/iam/aws4_request,
--- SignedHeaders=content-type;host;x-amz-date, Signature=xxx
local auth = aws:get_authorization_header()
-- get the x-amz-date header
local amz_date = aws:get_amz_date_header()
Add Authorization and x-amz-date header to ngx.req.headers
aws:set_ngx_auth_headers()
