Php Laravel：如何通过登录注册用户？

我正在使用身份验证控制器的标准登录/注册方法。目标是在用户登录时注册一个新用户（如果没有这样的用户），或者在有用户时只进行身份验证。在我看来，这应该只是重新分配几个方法。首先，我改变了

AuthenticatesUsers.php

    public function login(Request $request)
    {
        $this->validateLogin($request);

        // If the class is using the ThrottlesLogins trait, we can automatically throttle
        // the login attempts for this application. We'll key this by the username and
        // the IP address of the client making these requests into this application.
        if ($this->hasTooManyLoginAttempts($request)) {
            $this->fireLockoutEvent($request);

            return $this->sendLockoutResponse($request);
        }

        if ($this->attemptLogin($request)) {
            return $this->sendLoginResponse($request);
        }


        $this->incrementLoginAttempts($request);

        //return $this->sendFailedLoginResponse($request);
    }

With commenting the last line it will not say that there is no such user, and I believe right there I should put register method, but I can't find the right way to include it. I suggest that I should use `RegisterUsers.php`

AuthenticatesUsers.php是执行登录逻辑的控制器。我们正在查看公共功能登录

    AuthenticatesUsers.php
    <?php

namespace Illuminate\Foundation\Auth;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Validation\ValidationException;
use Illuminate\Support\Facades\Validator;
use Illuminate\Auth\Events\Registered;
use Illuminate\Foundation\Auth\RegistersUsers;

trait AuthenticatesUsers
{
    use RedirectsUsers, ThrottlesLogins, RegistersUsers;


    public function showLoginForm()
    {
        return view('auth.login');
    }

    public function login(Request $request)
    {
        $this->validateLogin($request);


        if ($this->hasTooManyLoginAttempts($request)) {
            $this->fireLockoutEvent($request);

            return $this->sendLockoutResponse($request);
        }

        if ($this->attemptLogin($request)) {
            return $this->sendLoginResponse($request);
        }


        $this->incrementLoginAttempts($request);

        //return $this->sendFailedLoginResponse($request);
        $this->register($request);
    }

    public function register(Request $request)
    {
        $this->validator($request->all())->validate();

        event(new Registered($user = $this->create($request->all())));

        $this->guard()->login($user);

        return $this->registered($request, $user)
            ?: redirect($this->redirectPath());
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [
            //'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users',
            //'password' => 'required|string|min:6|confirmed',
        ]);
    }

    protected function validateLogin(Request $request)
    {
        $this->validate($request, [
            $this->username() => 'required|string',
            'password' => 'required|string',
        ]);
    }

    protected function attemptLogin(Request $request)
    {
        return $this->guard()->attempt(
            $this->credentials($request), $request->filled('remember')
        );
    }

    protected function credentials(Request $request)
    {
        return $request->only($this->username(), 'password');
    }

    protected function sendLoginResponse(Request $request)
    {
        $request->session()->regenerate();

        $this->clearLoginAttempts($request);

        return $this->authenticated($request, $this->guard()->user())
                ?: redirect()->intended($this->redirectPath());
    }

    protected function authenticated(Request $request, $user)
    {
        //
    }

    protected function sendFailedLoginResponse(Request $request)
    {
        throw ValidationException::withMessages([
            $this->username() => [trans('auth.failed')],
        ]);
    }

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

    public function logout(Request $request)
    {
        $this->guard()->logout();

        $request->session()->invalidate();

        return redirect('/');
    }

    protected function guard()
    {
        return Auth::guard();
    }
}

AuthenticatesUsers.php
只需将
RegisterUsers.php
中的
register
方法覆盖到
LoginController

public function register(Request $request)
{
    $this->validator($request->all())->validate();

    event(new Registered($user = $this->create($request->all())));

    $this->guard()->login($user);

    return $this->registered($request, $user)
                    ?: redirect($this->redirectPath());
}

还可以从注册表控制器中添加
验证程序
受保护的功能，并根据您的字段进行编辑

还要记住编辑
用户
模型
可填充
数组和创建
用户
表的相对迁移文件。将
Nullable（）
设置为在
登录期间不打算输入的字段

 在LoginController中实现此方法

protected function attemptLogin(Request $request)
{
    // here you can check if user is present or just create.
    return $this->guard()->attempt(
        $this->credentials($request), $request->filled('remember')
    );
}

在LoginController中实现此方法

protected function attemptLogin(Request $request)
{
    // here you can check if user is present or just create.
    return $this->guard()->attempt(
        $this->credentials($request), $request->filled('remember')
    );
}

我所要做的就是转向用户模型，不需要指定任何方法
下面是
AuthenticatesUsers.php
中的函数的外观：

{
    $this->validateLogin($request);

    // If the class is using the ThrottlesLogins trait, we can automatically throttle
    // the login attempts for this application. We'll key this by the username and
    // the IP address of the client making these requests into this application.
    if ($this->hasTooManyLoginAttempts($request)) {
        $this->fireLockoutEvent($request);

        return $this->sendLockoutResponse($request);
    }

    if ($this->attemptLogin($request)) {
        return $this->sendLoginResponse($request);
    }

    // If the login attempt was unsuccessful we will increment the number of attempts
    // to login and redirect the user back to the login form. Of course, when this
    // user surpasses their maximum number of attempts they will get locked out.
    $this->incrementLoginAttempts($request);

    //return $this->sendFailedLoginResponse($request);
    $user = User::where('email', '=', $_POST['email'])->first();
    if ($user === null) {
        return User::create([
            'name' => $_POST['email'],
            'email' => $_POST['email'],
            'password' => Hash::make($_POST['password']),
        ]);
    }
    else
        echo 'Wrong password';
}

因此，当用户拼写错误的电子邮件/用户名时，用户将使用拼写错误的电子邮件/用户名登录到新帐户？如果电子邮件/用户名不是唯一的，如果用户拼错密码，他会创建新帐户吗？是的，如果他拼错密码，他将注册为新用户，请不要问我为什么需要这个。电子邮件必须是唯一的，我不会问你为什么需要它，我只是在此警告你，你的用户会讨厌它；-）因此，当用户拼写错误的电子邮件/用户名时，用户将使用拼写错误的电子邮件/用户名登录到新帐户？如果电子邮件/用户名不是唯一的，如果用户拼错密码，他会创建新帐户吗？是的，如果他拼错密码，他将注册为新用户，请不要问我为什么需要这个。电子邮件必须是唯一的，我不会问你为什么需要它，我只是在此警告你，你的用户会讨厌它；-）尝试了类似的操作，但不断出现错误，例如调用未定义的方法illumb\Validation\Validator:：make（）将其添加到控制器
