Siesta iOS POST request errors out with "unsupported URL"

Question

I am having trouble with Siesta - an iOS REST Client Framework https://bustoutsolutions.github.io/siesta/.

Below is a simple example of a POST request to a REST API server, which fails with a "unsupported URL" error. Does anybody out there have any experience with Siesta and what could be wrong?

Siesta configuration & login server call

let api = Service(base: "http://myapidomain.net/rest")

enabledLogCategories = LogCategory.all

let parameters = ["username": "username", "password": "password"]

api.resource(url: "users/login").request(.POST, json: NSDictionary(dictionary: parameters)).success { data in
    debugPrint("success logging in")
}.failure { error in
    debugPrint("failed to log in")
}

Debug log

The Service.resource(url:) method — the one with the parameter labeled url: — expects a complete URL. It looks like you want Service.resource(_:), which takes a path relative to the Service’s base URL.

Try:

api.resource("users/login")
