我正在与Laravel 8开发我的项目，我已经建立了这个形式验证令牌：

<div class="card-body">
    <form action="{{ route('profile.2fa.phone') }}" method="POST">
        @csrf

        <div class="form-group">
            <label for="token" class="col-form-label">Token</label>
            <input type="text" class="form-control @error('token') is-invalid @enderror" name="token" placeholder="enter your token">
            @error('token')
                <span class="invalid-feedback">
                <strong>{{ $message }}</strong>
            </span>
            @enderror
        </div>
        <div class="form-group">
            <button class="btn btn-primary">Validate token</button>
        </div>
    </form>
</div>

然后在web.php，我有这些路径：

Route::get('/settings/twofactor/phone' , [App\Http\Controllers\Admin\AdminSettingsController::class, 'getPhoneVerify']);

Route::post('/settings/twofactor/phone' , [App\Http\Controllers\Admin\AdminSettingsController::class, 'postPhoneVerify'])->name('profile.2fa.phone');

但现在，当我添加令牌并按下 Validate Token 按钮时，我收到以下错误：

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException此路由不支持GET方法。支持的方法：开机自检

那么，这里出了什么问题？我该如何解决这个问题？
我真的很感激你们的任何想法或建议...
先谢谢你。
以下是所有路线：

Route::get('/', function () {
    return view('welcome');
});

Route::prefix('admin')->middleware(['auth', 'verified'])->group(function() {
    Route::get('/', function () {
        return view('admin.index');
    });

    Route::resource('users' , App\Http\Controllers\Admin\AdminUserController::class)->middleware('admin');

    Route::get('/settings', [App\Http\Controllers\Admin\AdminSettingsController::class, 'index'])->name('profile');

    Route::post('/settings/twofactor' , [App\Http\Controllers\Admin\AdminSettingsController::class, 'postManageTwoFactor'])->name('profile.2fa.manage');

    Route::get('/settings/twofactor/phone' , [App\Http\Controllers\Admin\AdminSettingsController::class, 'getPhoneVerify']);
    Route::post('/settings/twofactor/phone' , [App\Http\Controllers\Admin\AdminSettingsController::class, 'postPhoneVerify'])->name('profile.2fa.phone');

    Route::get('/auth/token' ,[App\Http\Controllers\Auth\AuthTokenController::class, 'getToken'])->name('2fa.token');
    Route::post('/auth/token' ,[App\Http\Controllers\Auth\AuthTokenController::class, 'postToken']);
});

Auth::routes(['verify' => true]);

Route::get('/auth/google', [App\Http\Controllers\Auth\GoogleAuthController::class, 'redirect'])->name('auth.google');
Route::get('/auth/google/callback', [App\Http\Controllers\Auth\GoogleAuthController::class, 'result']);

Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->name('home');

Auth::routes();

Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->name('home');
