Laravel 登录注册模块常规流程

认证权限：文章权限

注册控制器：RegisterController.php

public function index() {
    return view('register.index');
}

public function register(){
    //验证
    $this->validate(request(),[
    'name'=>'required|min:3|max:50|unique:users,name',
    'email'=>'required|email|unique:user,email',
    'password'=>'required|min:6|max:20|confirmed'
    ]);

    //逻辑
    $name=request('name');
    $email = request('email');
    $password = bcrypt(request('password'));//加密
    $user = User::create(compact('name','email','password'));

    //渲染
    return redircet('/login');
}

Auth

Auth 来访问Laravel的认证服务，需要顶部映入Auth。

use  Illuminate\Support\Facades\Auth;
class  LoginController  extends  Controller  {
    public function authenticate()
    {
        //处理身份认证尝试
        if(Auth::attempt(['email' => $email,'password' => $password])){
        //认证通过
        return redirect()->intended('dashboard');
        }
    }
}

LoginController.php

//登录页面
public function index(){
    return view('login.index');
}

//登录
public function login(){
    //验证输入项
    $this->validate(request(),[
    'email'=>'required|email',
    'password'=>'required|min:6|max:20',
    'is_remeber'=>''
    ]);

    //登陆逻辑
    $user = request(['email','password']);
    $remeber = boolval(request('is_remeber'));
    if(\Auth::attempt($user,$remeber)){
        //登陆成功跳转到文章列表页
        return redirect('/posts');
    }

    //登陆验证不成功返回到登陆页面
    return \Redirect::back()->withErrors('用户名或者密码错误');
}

//退出登录
public function logout(){
    \Auth::logout();
    return redirect('/login');
}

用户授权

一、定义策略类
二、注册策略类和模型关联
三、策略判断

在PostController中的创建文章方法，新建文章时带上创建者的id

//创建文章
public function create()
{
    return view('post/create');
}

//保存新建文章
public function store(Request $request)
{
    //应对表单三步骤
    //1.验证
    $this->validate($request,{
        'title' =>'required|string|min:5|max:100',
        'content' => 'required|min:10'
    });
    //2.逻辑
    $parms = array_merge(request(['title','content']),['user_id'=>\Auth::id()]);
    Post::create($parms);
    //3.渲染
    return redirect('/posts');
}

修改model类，添加关联（一对多）

public function user()
{
    //第二个参数是model类中外键名，第三个是user表的主键名
    return $this->belongsTo("App\User",'user_id','id');
}

在Policie文件夹创建策略类XXPostPolicy添加权限

public function update(User $user, Post $post)
{
    return $user->id===$post->user_id;
}

public function delete(User $user,Post $post)
{
    return $user->id === $post->user_id;
}

在AuthServiceProvider映射对应的策略类

protected $policies = [
    'App\XXModel' => 'App\Policies\XXPolicy'
];

修改相关页面blade.php添加判断，有对应权限，再显示相关按钮
XXX.blade.php

<div>
@can('update',$post)
@endcan

</div>

登陆路由控制

//单条路由
Route::get('profile',fuction(){
    //只有登陆的用户才能进入
})->middleware('auth');

//路由组
Route::->group(['middleware'=>'auth'],function(){
    Route::get('/email_verify_notice','PagesController@emailVerifyNotice')->name('emailVerifyNotice');
    Route::get('email_verification/verify','EmailVerificationController@verify')->name('email_verification.verify');
});

同时修改登陆页面，用户已登陆时，输入login路由，直接跳到网站首页
app/Http/Controllers/LoginController.php

//登陆页面
public function index()
{
    if(\Auth::check()){
    return redirect('/home');
    }
    return view('login/index');
}
