登录后如何将用户重定向到同一页面？

我有一个login.blade.php，所以当用户访问“project.test / login”时，他有一个电子邮件和密码字段来登录 .

我还有一个header.blade.php，它有主菜单，在这个主菜单中有一个链接“Create congress” . 如果用户未经过身份验证并单击“创建 Session ”，则他不应该访问该页面，他应该被重定向到登录页面 . 登录成功后，他应该被重定向到“创建大会”页面 .

这工作正常 .

Doubt:

但是当用户访问“http://project.test/congress/1/congresstest/registration”时，我也有"registration.blade.php" . 当用户访问此页面时，如果未经过身份验证，则会显示以下消息：

@if(!\Auth::check())
    <div class="alert alert-info" role="alert">
        <span>
            Already have an account? 
            <a data-toggle="modal" 
            data-target=".bd-example-modal-lg" 
            class="font-weight-bold" href="">Login.</a>
        </span>
    </div>
@endif

如果用户在登录时单击，则会显示模式，因此用户可以插入电子邮件和密码，如果成功登录，模式应该关闭，应该将其重定向到同一个注册页面 .

问题是，如果用户在此页面中成功登录“http://project.test/congress/1/congresstest/registration " with the form in the modal he is redirected to the "创建大会”页面而不是停留在注册页面中 . 你知道如何纠正这个问题吗？

Relevant code for the question:

Login.blade.php:

<form class="clearfix" method="POST" action="{{ route('login') }}">
{{ csrf_field() }}
<div class="form-group col-12 px-0">
    <label for="inputEmail4">Email</label>
    <input type="email" class="form-control" value="{{ old('email') }}" name="email" required autofocus>
</div>
<div class="form-group col-12 px-0">
    <label for="inputEmail4">Password</label>
    <input type="password" class="form-control" name="password" required>
</div>
<button type="submit">Login</button>
</form>

LoginController:

class LoginController extends Controller
{
    use AuthenticatesUsers;
    protected $redirectTo = '/home';

    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    protected function authenticated(Request $request, $user)
    {
        return redirect()->intended($this->redirectTo);
    }
}

header.blade.php 主菜单中有一个创建新 Session 的链接：

<li>
    <a href="{!! route('congress.create') !!}"> Create Congress </a>
</li>

Modal with the login form:

<div class="modal fade bd-example-modal-lg" id="modal2" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-sm">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Login</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <div class="container">
          <div class="row">
            <form class="clearfix" method="POST" action="{{ route('login') }}">
              {{ csrf_field() }}

              <div class="form-group col-12 px-0">
                <label for="inputEmail4">Email</label>
                <input type="email" class="form-control" value="{{ old('email') }}" name="email" required autofocus>
              </div>

              <div class="form-group col-12 px-0">
                <label for="inputEmail4"
                       class="text-heading font-weight-semi-bold">Password
                  <a href="{{ route('password.request') }}" class="text-gray ml-1" style="text-decoration: underline">
                    <small>Recover Password</small></a> </label>
                <input type="password" class="form-control" name="password" required>
              </div>


              <button type="submit" class="btn btn-primary btn d-block w-100">Login</button>

            </form>
          </div>
        </div>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-primary" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>

Route::get('/', [
