Send application/x-www-form-urlencoded in Ktor

Question

I can't figure out how to send a application/x-www-form-urlencoded POST request in Ktor. I see some submitForm helpers in Ktor's documentation but they don't send the request as expected.

What I want is to replicate this curl line behavior:

curl -d "param1=lorem&param2=ipsum" \
     -H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8" \
     https://webservice/endpoint

My dependency is on io.ktor:ktor-client-cio:1.0.0.

Answer 1

After several tries I managed to send the request with the following code:

val url = "https://webservice/endpoint"
val client = HttpClient()
return client.post(url) {
    body = FormDataContent(Parameters.build {
        append("param1", "lorem")
        append("param2", "ipsum")
    })
}

Answer 2

val response: HttpResponse = client.submitForm(
    url = "http://localhost:8080/get",
    formParameters = Parameters.build {
        append("first_name", "Jet")
        append("last_name", "Brains")
    },
    encodeInQuery = true
)
