KCD works well with nested types and the path system solves almost all use cases.
package main
import (
"fmt"
"net/http"
"github.com/go-chi/chi"
"github.com/alexisvisco/kcd"
)
func main() {
r := chi.NewRouter()
r.Post("/", kcd.Handler(YourHttpHandler, http.StatusOK))
_ = http.ListenAndServe(":3000", r)
}
type NestedStruct struct {
Name string `query:"name"`
}
type CustomInput struct {
Nested NestedStruct `query:"nested"` // ?nested.name=kcd
NestedStruct // ?name=kcd
Anonymous struct{
Key string `query:"key"` // ?key=kcd
}
AnonymousValue struct{
Value string `query:"key"` // ?anonymous.key=kcd
NestedStruct // ?anonymous.name=kcd
} `query:"anonymous"`
}
func YourHttpHandler(in *CustomInput) (*CustomInput, error) {
fmt.Printf("%+v", in)
return in, nil
}
// Test it : curl -XPOST 'localhost:3000?nested.name=alexis&name=remi&key=antoine&anonymous.key=superman&anonymous.name=batman'
The path system only adds the parent to the path if the same corresponding tag is present.
The path system works only with query, ctx, path, and header tags. Since JSON decoding is handled by the default unmarshaler.
