                    <input name="" type="submit" class="btn btn-success radius size-L" value="&nbsp;登&nbsp;&nbsp;&nbsp;&nbsp;录&nbsp;">

                    <input name="" type="reset" class="btn btn-default radius size-L" value="&nbsp;取&nbsp;&nbsp;&nbsp;&nbsp;消&nbsp;">

                </div>

            </div>

        </form>

{{--        显示错误信息--}}

        @if (count($errors) > 0)

            <div class="alert alert-danger">

                <ul>

                    @foreach ($errors->all() as $error)

                        <li>{{ $error }}</li>

                    @endforeach

                </ul>

            </div>

        @endif

    </div>

</div>

<div class="footer">Copyright 你的公司名称 by H-ui.admin v3.1</div>

<script type="text/javascript" src="/static/lib/jquery/1.9.1/jquery.min.js"></script>

<script type="text/javascript" src="/static/static/h-ui/js/H-ui.min.js"></script>

<!--此乃百度统计代码，请自行删除-->

<script>

    var _hmt = _hmt || [];

    (function() {

        var hm = document.createElement("script");

        hm.src = "https://hm.baidu.com/hm.js?080836300300be57b7f34f4b3e97d911";

        var s = document.getElementsByTagName("script")[0];

        s.parentNode.insertBefore(hm, s);

    })();

</script>

</body>

</html>

3：提交表单路由：

Route::group(['prefix'=>'day','namespace'=>'day18'],function (){

//    处理登录

    Route::post('dologin','ExamController@doLogin');

});

4：提交控制器验证


    public function doLogin(Request $request){
//        去除token
        $params=$request->except('_token');
//        验证非空
        $this->validate($request, [
            'username' => 'required',
            'password' => 'required'
        ], [
            'username.required' => '账号不可以为空',
            'password.required' => '密码不可以为空'
        ], $params);
//        匹配数据库
       $res=Admins::login($params);
//       验证账号和密码
       if ($res['username']!==$params['username']){
           return redirect(url('day/login'))->withErrors(['error'=>'账号错误']);
       }elseif ($res['password']!==md5($params['password'])){
           return redirect(url('day/login'))->withErrors(['error'=>'密码错误']);
       }else{
//           记录session通过put方法
           $request->session()->put('username', $res['username']);
//通过全局辅助函数
//           session(['username' => $res['username']);
//验证成功跳转首页
           return redirect(url('day/new'))->with('success','登录成功');
       }

    }

5：模型代码：

<?php

namespace App\models;

use Illuminate\Database\Eloquent\Model;

class Admins extends Model

{

    //链接表名

    protected $table = 'admins';

//验证数据

    public static function login($params)

    {
//验证账号

        return self::where('username',$params['username'])

            ->first();

    }

}
