Hi, is there some way we can define a variable with "-" ? sometimes json data from request may has some field name with "-", how to defined a correspond variable in data class ?
the json data could be { "refresh-token" : "some thing" }
I got error like this:

For JSON, you can use the JsonNames annotation, such as

@JsonNames("refresh-token") val token: String

In general, I believe there’s a SerialName annotation that works for all serializers, but only supports one name.

it works! I've been waste a lot time searching how to define a varible with "-"😀

[Landry Norris]

I would imagine you could write `val `refresh-token`: String` , but that would be terrifying. I know backticks work for methods, and I think they work for variables (but I wouldn’t recommend them)

use @SerialName instead of @JsonNames so that it works with other formats and with serialization as well. @JsonNames is more useful for coalescing a number of alternative names to one during deserialization.
