Laravel 5.7 认证

Question

我是新手，正在学习laravel 5.7。注册已完成，但在登录期间验证时遇到问题，Auth::attempt 总是 returns false

我尝试使用 Hash::check('plain-text','Hashed password) 结果 returns 正确问题是 Auth::attempt 总是 returns false

UserController.php:

// Registration code
public function register(Request $request){
       $request->validate([
            'firstName' => 'required',
            'lastName' => 'required',
            'username' => 'required|min:3',
            'password' => 'min:6|required_with:confirm_password|same:confirm_password',
            'confirm_password' => 'min:6'
        ]);

        Users::create([
            'firstName' => request('firstName'),
            'lastName' => request('lastName'),
            'username' => request('username'),
            'password' => Hash::make(request('password'))
        ]);
        notify()->success('Registered Successfully!');
        return redirect('/');

    }

// Login code
public function login(Request $request){

//      This returns true
//        if(Hash::check('123456','y$BrOg1JtnX7hAX05gbT9p0OZFQB9mFKtcz0m5Ks2rSHIN//B20dODgA.')){
//            return 'OK';
//        }


        $credentials = request([
            'username',
            'password'
        ]);


// Always returns false
        if(Auth::attempt($credentials)){
            notify()->success('Welcome!');
            return back();

        }else{
            notify()->warning('Credentials not found!');
            return back();
        }




    }

Users.php:

//Model
class Users extends Model 
{
    //
    protected $guarded = [];


}

auth.php:

'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\Users::class,
        ],

        // 'users' => [
        //     'driver' => 'database',
        //     'table' => 'users',
        // ],
    ],

迁移：

 public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('username')->unique();
            $table->string('password');
            $table->string('firstName');
            $table->string('lastName');
            $table->rememberToken();
            $table->timestamps();
        });
    }

login.blade.php:

<form action="/" method="post" autocomplete="on">
                        @csrf
                        <h1>Log in</h1>
                        <p>
                            <label for="Username"  data-icon="u"> Username</label>
                            <input id="Username" name="username" required="required" type="text" placeholder=""/>
                        </p>
                        <p>
                            <label for="Password"  data-icon="p"> Password </label>
                            <input id="Password" name="password" required="required" type="password" placeholder=""/>
                        </p>
                        <p class="login button">
                            <input type="submit" value="Login"/>
                        </p>
                        <p class="change_link">
                            Not a member yet ?
                            <a href="/register" class="to_register">Join us</a>
                        </p>
                    </form>

注意

我确信我得到了正确的输入

// Returns correct information
{
"username": "yeah",
"password": "123456"
}

Answer 1

Laravel 默认使用 email 来授权用户，因此请尝试覆盖您在 LoginController 中使用的字段，添加以下内容：

public function username()
{
    return 'username';
}

Answer 2

您不需要尝试重写登录功能（既不注册），因为这些功能在 Laravel 中开箱即用。您需要做的是：

在您的 login.blade.php

中排名第一

<form action="/login" method="post" autocomplete="on">

然后在你的 web.php

Route::post('login', 'Auth\LoginController@login');

现在去你的App\Http\Auth\LoginController

// Add this function to overwrite default email to username
public function username()
{
    return 'username';
}
