【菜鸟】Php Lumen框架学习笔记--查询构造器

一、背景

#####最近组里准备搞一个项目，以php lumen框架为基础。由于没有学过php语言更别说lumen框架，于是现在狂补中。

二、学习记录

1.新建controller

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use App\User;
use Auth;

class UserController extends Controller
{
	public function __construct()
    {
        //
    }

	public function index(){
        $user = DB::table('users')->get();
        $result = DB::select('select * from users');//查询users表
        foreach ($result as $res){
            echo $res->password . PHP_EOL;//遍历数据库，输出users.password
        }
        return view('index',['users' => $user]);//返回视图

    }
}

2.新建UserMiddleware

<?php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2018/9/29 0029
 * Time: 16:49
 */

namespace App\Http\Middleware;


class UserMiddleware
{
    /*public function handle($request,Closure $next){
        echo 11;
        return $next($request);
    }*/
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        //echo 11;
        return $next($request);
    }
}

3.新建路由

$router->get('user', '[email protected]');

//url后带user时调用user方法

4.新建index视图

//resources/view下新建视图，经测试视图默认名为xxx.blade.php
<?php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2018/9/30 0030
 * Time: 9:51
 */
 //输入逻辑代码
?>

5.网页输入url，访问即可。
