Can't get JSON data from Rails API

问题

I make a get request to http://localhost:3000/cars/1 but server does not reply json data. It says like that

Started GET "/api/cars/1" for 127.0.0.1 at 2016-10-07 12:47:34 +0600
Processing by Api::V1::CarsController#show as HTML
Parameters: {"id"=>"1"}
User Load (0.5ms)  SELECT  "users".* FROM "users" WHERE "users"."uid"       = $1 LIMIT $2  [["uid", "sahidul03@gmail.com"], ["LIMIT", 1]]
Car Load (0.6ms)  SELECT  "cars".* FROM "cars" WHERE "cars"."id" = $1    LIMIT $2  [["id", 1], ["LIMIT", 1]]
User Load (1.0ms)  SELECT  "users".* FROM "users" WHERE "users"."id" = $1 LIMIT $2  [["id", 1], ["LIMIT", 1]]
Started GET "/" for 127.0.0.1 at 2016-10-07 12:47:34 +0600

Parameters: {"internal"=>true}

(6.8ms)  COMMIT
Completed 200 OK in 25ms (Views: 1.3ms | ActiveRecord: 11.8ms)

My controller method is like that

 def show
   car= Car.find(params[:id])
   render json: car
 end

Front-end request is

  function getCar(id) {
        return $http.get($auth.domain + '/api/cars/' + id);
    }

I use devise_token_auth gem in back-end and ng-token-auth in front-end

回答1:

Append .json to the URL

$http.get($auth.domain + '/api/cars/' + id + '.json');

Hope that helps!
