Note that you can't use lowercase struct field names with encoding/json anyway, because fields must be exported for encoding/json to see them, and fields are exported by starting them with an uppercase letter. So if you want the JSON field names to be lower case, you have to use struct tags. I think that while Tamás's solution should work, you probably just want the type field to be in LoginRequest itself:
type LoginRequest struct { Type string `json:"type"` User string `json:"username"` Password string `json:"password"` } On Sun, Jan 22, 2017 at 12:48 PM Tamás Gulácsi <tgulacs...@gmail.com> wrote: > TL;DR; use struct tags to specify marshal/unmarsal names. > > type LoginRequest struct { > > User string `json:"username"` > Passw string `json:"password"` > } > > ... > > SetBody(struct { > Type string `json:"type"` > LoginRequest > }{ > Type: "LoginRequest", LoginRequest:{User:"my_admin", > Passw:"testing123"}}) > > > > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
