laravel 验证码 auth方式登录 中间件判断session是否存在
首先下载laravel的插件 composer下载 实现验证码 composer require mews/captcha
在config/app.php进行配置
‘providers’ => [ // … Mews\Captcha\CaptchaServiceProvider::class, ] ‘aliases’ => [ // … ‘Captcha’ => Mews\Captcha\Facades\Captcha::class, ]
终端手脚架运行 php artisan vendor:publish 10
生成 captcha.php文件 在文件中更改默认配置
编写 只有用户名 密码 验证码的 登录 的html页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>登录页面</title>

<input type="text" class="form-input" name="captcha" placeholder="请输入验证码">
</div>
<button type="submit" class="btn btn-default">登录</button>
</form>

auth方式验证用户信息
<?php namespace App\Models; use \Illuminate\Foundation\Auth\User as AuthUser;
//创建模型层 继承laravel自带user验证
class LoginModel extends AuthUser
{
//绑定数据表 也创建直接绑定表的model
protected $table = 'logins' ;
//设置隐藏字段
protected $guarded =[];
}
脱坑 测试时用户数据库密码 //www.jisuan.mobi/p163u3BN66Hm6JWx.html 可以修改数据库测试密码
在 config/auth.php 中修改 绑定的模型层
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => \App\Models\LoginModel::class,
],
手脚架 创建中间件 php artisan make:middleware CheckAge
这里写的是全局路由前置中间件 见 laravel手册 //learnku.com/docs/laravel/5.8/middleware/3891
app/Http/Kernel.php 中的 $routeMiddleware 属性中列出这个中间件
protected $routeMiddleware = [
'login' => \App\Http\Middleware\LoginkAge::class,
];
路由
Route::get('list','UsersController@list')->name('week2.list')->middleware('login'); // 路由中 middleware（注册的名字） 在分组也可以用
中间件文件写入
public function handle($request, Closure $next)
{
//auth验证用户是否登录
if (!auth()->check()&&!($request->session()->get('name'))
){ return redirect(route('week2.index'),302); } return $next($request); }
控制器接收处理全部数<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class LoginController extends Controller
{
// 登录页面
public function index(){
return view('week2.login');
}
// 登录处理
public function login(Request $request){
$posts['captcha'] = $request->input('captcha');
$rule = [
'captcha'=>'required|captcha',
];
$massage = [
'captcha.required'=>'验证码不为空',
'captcha.captcha'=>'验证码错误',
];
$validate = Validator::make($posts,$rule,$massage);
if ($validate->fails()) {
return $validate->errors()->first() ;
}
$post = $request->input('_token');
$post = $request->validate([
"username" => 'required',
'password' => 'required',
],[
'username.required' =>'用户名不为空',
'password.required' =>'密码不为空',
]);
//查询是否正确
$bool = auth()->attempt($post);
if (!$bool){
return view('week2.login');
}
//正确跳转到 欢迎页面
$request->session()->put('name',$post);
return redirect(route('week2.list'),302); } }
