1.创建路由

//新闻系统
    Route::get('/admins/article/index','Article@index');//文章列表
    Route::get('/admins/article/add','Article@add');//文章添加
    Route::post('/admins/article/save','Article@save');//文章保存
    Route::post('/admins/article/del','Article@del');//删除文章
    Route::get('/admins/article/cates','Article@cates');//文章分类
    Route::get('/admins/article/add_cate','Article@add_cate');//添加文章分类
    Route::post('/admins/article/save_cate','Article@save_cate');//保存文章分类
    Route::post('/admins/article/del_cate','Article@del_cate');//删除文章分类
    // 上传系统
    Route::post('/admins/files/upload_img','Files@upload_img');//文章缩略图上传

2. 创建后台控制器

利用laravel的artisan命令轻松创建

php artisan make:controller admins/Article
php artisan make:controller admins/Files

3. 控制器代码

<?php
namespace App\Http\Controllers\admins;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Auth;

        $data['article']=DB::table('article')->where('id',$aid)->item();
        $data['contents']=DB::table('article_detail')->where('aid',$aid)->item();
        $data['cates']=DB::table('article_cate')->lists();
        return view('admins/article/add',$data);
    }
    // 保存新闻
    public function save(Request $request)
