I am trying to unmarshal a json response from the server into various types, but I am not finding how to do it.
The types which work are :-
type ServerResponse struct {
Total int
Data []User
}
type User struct {
Name string
Age int
}
and I can successfully unmarshal the json and receive the expected User type.
What I want to do is handle various server responses and convert after the fact. eg.
type ServerResponse struct {
Total int
Data []ServerItem
}
type User struct {
ServerItem
Name string
Age int
}
type Book struct {
ServerItem
Name string
Author string
}
Then use either User(response.Data) or response.Data.(User) to make it a concrete type so that later functions type check correctly.
Please could anyone let me know where to start looking to solve this issue.
I don't think that this can be done easily. Just decode to map[string]interface{}
and create your stuff from this.
Here I wrote a simple program that parses json http://play.golang.org/p/51eiswgznR .
