Question

我有一个laravel后端，我想在我的前端显示成功消息下面是我的BackEnd控制器和角度2的前端。我怎样才能显示成功消息？

//后端

public function delete($id)
    {
        $food = food::all()->where('id', $id)->find($id);
        if(is_null($food)){
            return response()->json([
                'msg' => 'Dish could not be found',
                'retry' => true
            ], 404);
        }
        elseif($food->delete()){
            return response()->json([
                'msg' => 'Dish successfully deleted',
                'retry' => false
            ], 202);
        }
        else
            return response()->json([
                'msg' => 'An error occured ',
                'retry' => true
            ], 404);
    }
}

//存放菜肴

  $food->name = $request->name;
            $food->location = $request->location;
            $food->type = $request->type;
            $food->save();
            return 'Dish Record successfully added '

//前端

  <div class="form-group">

              <form (ngSubmit)="onSubmit(f)" #f="ngForm" >



                <div class="form-group">
                  <label for="name"> Name</label>
                  <input type="text" class="form-control" id="name" [(ngModel)]="food.name" name="name" required>
                </div>

                <div class="form-group">
                  <label for="location">location</label>
                  <input type="text" class="form-control" id="location"  [(ngModel)]="food.location" name="location" required>
                </div>
    <div class="form-group">
                  <button type="submit" class="btn btn-primary">Submit</button>
                  &nbsp; &nbsp;
                  <button type="submit" class="btn btn-danger ">Cancel</button>
                </div>

// api调用删除

 deleteFood(id) {
    return this.http.delete('http://example.com ' + id)
      .map((response:Response) => response.json())
  }

以角度形式显示成功消息
