lua-resty-aws

AWS signature V4 library for OpenResty + Lua.

Overview

This library implements request signing using the AWS Signature Version 4 specification. This signature scheme is used by nearly all AWS services.

Example

#You're limited by your max_body_size (and memory it may take up)
client_max_body_size 1G;
client_body_buffer_size 1024M;
client_body_in_single_buffer on;

map $request_uri $request_uri_no_parameters {
    "~^(?P<path>.*?)(\?.*)*$"  $path;
}

location / {
    set $s3_host s3.amazonaws.com;
    set $s3_uri $request_uri_no_parameters;
    access_by_lua "local aws = require 'resty.aws'; aws.s3_set_headers(ngx.var.access_key, ngx.var.secret_key, ngx.var.s3_host, ngx.var.s3_uri)";
    proxy_pass https://$s3_host$s3_uri;
}
