Laravel 开发用户认证与登陆

1.使用语言包在resources/lang/ 下的en 复制一份改成 zh_CN

config/app.php 中 locale 设置为 zh_CN

修改zh_CN 里的错误提示改成中文

2.我们通过 Composer 安装 Captcha 扩展包：

composer require mews/captcha

配置：

使用Captcha服务提供者之前还需要在config/app.php中注册服务提供者：

'providers' => [
    // ...
    Mews\Captcha\CaptchaServiceProvider::class,
]

同时注册下相应门面：

'aliases' => [
    // ...
    'Captcha' => Mews\Captcha\Facades\Captcha::class,
]

3.在登陆模版加入验证码：

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row">
        <div class="col-md-8 col-md-offset-2">
            <div class="panel panel-default">
                <div class="panel-heading">Login</div>
                <div class="panel-body">
                    <form class="form-horizontal" role="form" method="POST" action="">
                        {{ csrf_field() }}

                        <div class="form-group{{ $errors->has('email') ? ' has-error' : '' }}">
                            <label for="email" class="col-md-4 control-label">E-Mail Address</label>

                            <div class="col-md-6">
                                <input id="email" type="email" class="form-control" name="email" value="{{ old('email') }}" required autofocus>

                                @if ($errors->has('email'))
                                    <span class="help-block">
                                        <strong>{{ $errors->first('email') }}</strong>
                                    </span>
                                @endif
                            </div>
                        </div>

                        <div class="form-group{{ $errors->has('password') ? ' has-error' : '' }}">
                            <label for="password" class="col-md-4 control-label">Password</label>

                            <div class="col-md-6">

Controllers/Auth/LoginController.php 内加入对验证码的的验证，重构validateLogin方法

<?php

namespace App\Http\Controllers\Auth;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest', ['except' => 'logout']);
    }
    protected function validateLogin(Request $request)
    {
        $this->validate($request, [
            $this->username() => 'required|email|max:255', 'password' => 'required|min:6','captcha' => 'required|captcha',
        ]);
    }
}

对应验证的错误信息：

在中文包下zh_CN\validation.php加入

    'captcha'              => '验证码不一致',
