一、前台首页数据
1.1 创建控制器
运行命令php artisan make:controller Web/IndexController
写入首页获取数据方法：
<?php
namespace App\Http\Controllers\Web;
use App\Http\Controllers\BaseController;
use App\Models\Good;
use App\Models\Slide;
class IndexController extends BaseController
{
// 首页数据
function index() {
// 轮播图数据
$slides = Slide::where('status', 1)
->orderBy('seq') // 排序 默认正序
->get();
// 分类数据 没被禁用的分类
$categories = cache_category();
// 推荐商品
$goods = Good::where('is_on', 1) // 上架的商品
->where('is_recommend', 1) // 推荐的商品
->get();
return $this->response->array([
'slides' => $slides,
'categories' => $categories,
'goods' => $goods,
]);
}
}
1.2 前台路由
routes/api.php这里写我们的前台路由：
<?php
use App\Http\Controllers\Web\IndexController;
$api = app('Dingo\Api\Routing\Router');
$api->version('v1', function ($api) {
// 首页数据，不需要登陆就能获取
$api->get('/index', [IndexController::class, 'index']);
// 需要登陆的路由
$api->group(['middleware' => ['api.auth', 'check.permission']], function ($api) {
});
});
1.3 创建分类填充
运行命令php artisan make:seed CategorySeeder 创建分类的填充文件：
对分类进行数据添加：
<?php
namespace Database\Seeders;
use App\Models\Category;
use Illuminate\Database\Seeder;
class CategorySeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
// 填充分类信息
$categories = [
[
'name' => '电子产品',
'group' => 'goods',
'pid' => 0,
'level' => 1,
'children' => [
[
'name' => '手机',
'group' => 'goods',
'level' => 2,
'children' => [
[
'name' => '华为',
'group' => 'goods',
'level' => 3,
],
[
'name' => 'oppo',
'group' => 'goods',
'level' => 3,
],
]
],
[
'name' => '相机',
'group' => 'goods',
'level' => 2,
'children' => [
[
'name' => '索尼',
'group' => 'goods',
'level' => 3,
],
[
'name' => '佳能',
'group' => 'goods',
'level' => 3,
],
]
]
]
],
[
'name' => '车',
'group' => 'goods',
'pid' => 0,
'level' => 1,
'children' => [
[
'name' => '轿车',
'group' => 'goods',
'level' => 2,
'children' => [
[
'name' => '红旗',
'group' => 'goods',
'level' => 3,
],
[
'name' => '吉利',
'group' => 'goods',
'level' => 3,
],
]
],
[
'name' => '自行车',
'group' => 'goods',
'level' => 2,
'children' => [
[
'name' => '小黄车',
'group' => 'goods',
'level' => 3,
],
[
'name' => '小蓝车',
'group' => 'goods',
'level' => 3,
],
]
]
]
]
];
// 填充到数据库
foreach($categories as $one) {
$l1 = $one;
unset($l1['children']);
$l1_model = Category::create($l1);
foreach($one['children'] as $two) {
$l2 = $two;
unset($l2['children']);
$l2['pid'] = $l1_model->id;
$l2_model = Category::create($l2);
$l2_model->children()->createMany($two['children']);
}
}
// 清除缓存
forget_cache_category_all();
}
}
执行填充命令：php artisan db:seed --class=CategorySeeder
