uses
Horse,
Horse.Jhonson, // It's necessary to use the unit
System.JSON;
begin
// It's necessary to add the middleware in the Horse:
THorse.Use(Jhonson());
// You can specify the charset when adding middleware to the Horse:
// THorse.Use(Jhonson('UTF-8'));
THorse.Post('/ping',
procedure(Req: THorseRequest; Res: THorseResponse; Next: TProc)
var
LBody: TJSONObject;
begin
// Req.Body gives access to the content of the request in string format.
// Using jhonson middleware, we can get the content of the request in JSON format.
LBody := Req.Body<TJSONObject>;
Res.Send<TJSONObject>(LBody);
