laravel5.5 可以使用eloquent API Resources轻松构建api
https://laravel.com/docs/5.5/eloquent-resources
首先按照文档，我们新建article resource和article collection
php artisan make:resource ArticleResource
php artisan make:resource ArticleCollection
运行命令后会在Http目录下新建Resources目录，并新建ArticleResource.php和ArticleCollection.php
ArticleResource.php
public function toArray($request)
{
return [
'id' => $this->id,
'title' => $this->title,
'image' => $this->image,
'keywords' => $this->keywords,
'description' => $this->description,
'content' => $this->content,
];
}可以根据api自主显示字段
ArticleCollection.php
public function toArray($request)
{
return [
'data' => $this->collection
];
}在Http的Controlles目录下新建Api目录，并建立ArticleApiController.php
在这里，我们需要用到帮助函数，在App目录下新建Helpers目录，并建立functions.php文件， 然后再composer.json中添加自动加载
在autoload节点下添加
"autoload": {
"classmap": [
"database/seeds",
"database/factories"
],
"psr-4": {
"App\\": "app/"
},
"files": [
"app/Helpers/functions.php"
]
},这样就可以自动加载了
我们需要在帮助文件中获取子栏目的id
我这里只考虑二级栏目
// 获取子栏目
function getChildrenIds($parent_id) {
$children = App\Models\Category::select('id')->where('parent_id', $parent_id)->orderBy('order')->orderBy('id')->get();
$children_arr = [];
foreach($children as $key => $val) {
$children_arr[] = $val['id'];
}
return $children_arr;
}帮助文件建立好后在回到ArticleApiController.php
常规的我们就只需要列表和详情就可以了
public function index($category = '') {
$children = getChildrenIds($category);
if (empty($children)) {
return new ArticleCollection(Article::select(['id', 'category_id', 'title', 'image'])->where('category_id', $category)->paginate());
} else {
$category_id = $children;
return new ArticleCollection(Article::select(['id', 'category_id', 'title', 'image'])->whereIn('category_id', $children)->paginate());
}
}public function show($id) {
return new ArticleResource(Article::find($id));
}然后添加路由
Route::group([
'prefix' => 'api',
'namespace' => "Api",
], function (Router $router) {
$router->get('articles/{category?}', 'ArticleApiController@index');
$router->get('article/{id}', 'ArticleApiController@show');
$router->get('products/{category?}', 'ProductApiController@index');
$router->get('product/{id}', 'ProductApiController@show');
$router->get('jobs/{category?}', 'JobApiController@index');
$router->get('job/{id}', 'JobApiController@show');
$router->get('pages/{category}', 'PageApiController@index');
$router->get('categories', 'CategoryApiController@tree');
$router->get('category/{id}', 'CategoryApiController@show');
$router->get('children/{id}', 'CategoryApiController@children');
$router->get('config', 'ConfigApiController@config');
});其他的页面跟article一样
接下来就是建立前端页面，pc端直接在Controllers目录下新建IndexController.php，手机端在Controllers目录下建立Mobile目录，并建立IndexController.php，内容大同小异
public function articles() {
return view('article.index');
}
public function article() {
}在resource目录下的view目录下新建article目录和mobile/article目录，并建立index.blade.php和show.blade.php
输出内容随意可以，只有能显示出来就好，
为前端页面建立路由
Route::get('/', 'IndexController@index');
Route::get('articles/{category?}', 'IndexController@articles');
Route::get('article/{id}', 'IndexController@article');
Route::get('products/{category?}', 'IndexController@products');
Route::get('product/{id}', 'IndexController@product');
Route::get('jobs/{category?}', 'IndexController@jobs');
Route::get('job/{id}', 'IndexController@job');
Route::get('pages/{category?}', 'IndexController@page');
Route::group([
'prefix' => 'mobile',
'namespace' => "Mobile",
], function (Router $router) {
$router->get('/', 'IndexController@index');
$router->get('articles/{category?}', 'IndexController@articles');
$router->get('article/{id}', 'IndexController@article');
$router->get('products/{category?}', 'IndexController@products');
$router->get('producte/{id}', 'IndexController@product');
$router->get('jobs/{category?}', 'IndexController@jobs');
$router->get('job/{id}', 'IndexController@job');
$router->get('pages/{category?}', 'IndexController@page');
});
