Example with path parameters doesn't work

[spawn-guy]

as the example has delimiter=/ the provided code doesn't work.

here is my solution

var fullPath = request.url.replace(request.scheme+'://'+request.host, '');

var opts = {service: 's3', host: request.host, path: fullPath, region:'eu-west-1'};
var awsObj = aws4.sign(opts, {accessKeyId: variables.get("AWS_ACCESS_KEY_ID"), secretAccessKey: variables.get("AWS_SECRET_ACCESS_KEY")});

request.path = awsObj.path;

for (var header in awsObj.headers) {
    request.headers[header] = awsObj.headers[header];
}

replace scheme and host. the rest of the URL will be path+params

also, region is detected poorly with this implementation. i had to set it explicitly as i was getting error that s3-eu-west-1 is not a valid region
