Laravel 5.7 登录没有重定向或错误

Question

I'm new to Laravel so I started following lessons on Laracast then the guy who gave the lessons went to the authentication of a user and guessed etc. The register works fine and it goes into the databases with hashed passwords and it keeps that user that just registered login (and can do all the stuff a login user is supposed to be doing on the website). When I go to my login form and try to log in it doesn't redirect and give errors. It just reloads even when user/password credentials are not correct.

It's needed to register how it saves the user into the database.

$user = User::create([
    'name' => request('name'),
    'email' => request('email'),
    'password' => bcrypt(request('password'))
]);

login form...

<form method="POST" action="/login">
    {{ csrf_field() }}
    <div class="form-group">
        <label for="Email">Email:</label>
        <input type="email" class="form-control" id="Email" name="Email" required>
    </div>

    <div class="form-group">
        <label for="password">Password:</label>
        <input type="password" class="form-control" id="password" name="password" required>
    </div>

    <div class="form-group">
        <button type="submit" class="btn btn-primary">Sign in</button>
    </div>
    @include ('layouts.errors')
</form>

web.php for routing

 Route::get('/', 'PostsController@index')->name('home');
 Route::get('/posts/create', 'PostsController@create');
 Route::post('/posts', 'PostsController@store');
 Route::get('/posts/{post}', 'PostsController@show');

 Route::post('/posts/{post}/comments', 'CommentsController@store');

 Route::get('/register', 'RegistrationController@create');
 Route::post('/register', 'RegistrationController@store');
 Route::get('/login', 'SessionsController@create')->name('login');
 Route::post('/login', 'SessionsController@store');
 Route::get('/logout', 'SessionsController@destroy');

The controller that handles the login

<?php

class SessionsController extends Controller
{
    public function __construct()
    {
        $this->middleware('guest');
    }

    public function create()
    {
        return view('sessions.create');
    }

    public function store()
    {
        // Attempt to authenticate the user.
        if (!auth()->attempt(request(['email', 'password']))) {
            return back();
        }
        // Redirect them to the homepage
        return redirect()->home();
    }

    public function destroy()
    {
        auth()->logout();
        return redirect()->home();
    }
}

Errors.php

<div class="form-group">
  <div class="alert alert-errors">
        <ul>
            @foreach($errors->all() as $error)
                <li> {{ $error }} </li>
            @endforeach
        </ul>
    </div>
</div>

Answer 1

Have a look at your form. The names of the inputs are the one that are needed in the controller to access them.

In the form you declared Email and password .

 ...
<input type="email" class="form-control" id="Email" name="Email" required>
....
<input type="password" class="form-control" id="password" name="password" required>
...

In the Controller you try to access email and password .

if (! auth()->attempt(request(['email', 'password']))) {

This might be the reason why the login fails and you just got redirected to the Page, because the executed code is

return back(); 

So change your form to

     ....

    <div class="form-group">

        <label for="Email">Email:</label>

        <input type="email" class="form-control" id="email" name="email" required>

    </div>
    .....

Let me know if this is working.
