Why only headers.append have a method with HeaderValueWithParameters as second parameter and other append* don't? If only append should have this, then this doc needs to be fixed: https://api.ktor.io/ktor-client/ktor-client-core/io.ktor.client.plugins/-default-request/index.html (see "usage" box).

In the append(name: String, value: HeaderValueWithParameters) the append(name, value.toString()) is called so you can use the toString method in your code:

val headers = HeadersBuilder()
headers.append("", ContentType("application", "json"))
headers.appendIfNameAbsent("", ContentType("application", "json").toString())

Feel free to file a feature request if you think that having those overloads is necessary in Ktor.

Thanks Aleksei, was just wondering whether this was intentional. Please fix the linked doc then.

I’ve created an issue to address the problem with a compilation error.
