How to send Http Form with parameters by ktor-client

Question

I've found nearly everywhere in ktor-client documentation and examples they use empty formData to show how the client works

formParameters: Parameters = Parameters.Empty

So what's the kotlin/ktor way to fill it with parameters?

Answer 1

Ktor uses this approach to fill the parameters:

client.submitForm<HttpResponse>(
        url = "https://foo.com/login",
        formParameters = Parameters.build {
            append("_username", username)
            append("_password", password)
        })
