Swift Example

    let rest = CkoRest()
    var success: Bool

    //  URL: https://api.stripe.com/v1/tokens

    var port: Int = 443
    var bAutoReconnect: Bool = true
    success = rest.Connect("api.stripe.com", port: port, tls: bTls, autoReconnect: bAutoReconnect)
    if success != true {
        print("ConnectFailReason: \(rest.ConnectFailReason.integerValue)")
        print("\(rest.LastErrorText)")
        return
    }

    rest.SetAuthBasic("STRIPE_SECRET_KEY", password: "")

    rest.AddQueryParam("card[number]", value: "4242424242424242")
    rest.AddQueryParam("card[exp_month]", value: "12")
    rest.AddQueryParam("card[exp_year]", value: "2019")
    rest.AddQueryParam("card[cvc]", value: "123")

    var strResponseBody: String? = rest.FullRequestFormUrlEncoded("POST", uriPath: "/v1/tokens")

        print("\(rest.LastErrorText)")
        return
