            content_by_lua_block {
                local s3_client = require "resty.aws_s3.client"
                local client, err, msg = s3_client.new(os.getenv("AWS_ACCESS_KEY_ID"),
                                                       os.getenv("AWS_SECRET_ACCESS_KEY"),
                                                       os.getenv("AWS_S3_ENDPOINT"),
                                                       os.getenv("AWS_S3_REGION"))
                if err ~= nil then
                    ngx.say('failed to new s3_client')
                    ngx.exit(ngx.HTTP_OK)
                end

                local presigned_url, err, msg = client:generate_presigned_url(
                        'get_object', {Bucket=os.getenv("S3_BUCKET_NAME"), Key=ngx.var.uri},
                        {ExpiresIn=3600, https=true})
                if err ~= nil then
                    ngx.say('failed to genearte presigned get object url')
                    ngx.exit(ngx.HTTP_OK)
                end

                ngx.say('presigned download url: ' .. presigned_url)
                
            }
        }
    }
