php - Laravel 5.4 : controller method is called twice on a redirect to it

Question

我遇到一个问题，从一个路由重定向到另一个路由两次调用目标 Controller 方法。 This question解决了类似的问题，但传递 301 状态代码的 OP 被认为是 accepted answer 中的问题，并且我没有指定任何状态代码。我也在使用 session 状态作为参数。相关代码如下所示:

public function origin(Request $request) {
  // Assume I have set variables $user and $cvId
  return redirect()
    ->action('SampleController@confirmUser')
    ->with([
      'cvId' => $cvId,
      'userId' => $user->id,
     ]);
}

public function confirmUser(Request $request) {
  $cvId = session()->get('cvId');
  $userId = session()->get('userId');

  if (is_null($cvId) || is_null($userId)) {
    // This is reached on the second time this is called, as 
    // the session variables aren't set the second time
    return redirect('/home');
  }

  // We only see the view for fractions of a second before we are redirected home
  return view('sample.confirmUser', compact('user', 'cvId'));
}

有什么想法可能导致这种情况吗？我没有 next中间件或在 Controller 执行两次的相关问题中建议的任何其他可能原因。
谢谢你的帮助!

Answer 1

您是否尝试过在参数中传递值？试试下面的代码。

public function origin(Request $request) {
  // Assume I have set variables $user and $cvId
  return redirect()->action(
    'SampleController@confirmUser', ['cvId' => $cvId, 'userId'=>$user->id]
);
}

public function confirmUser(Request $request) {
  $cvId = $request->cvId;
  $userId = $request->userId;

  if (is_null($cvId) || is_null($userId)) {
    // This is reached on the second time this is called, as 
    // the session variables aren't set the second time
    return redirect('/home');
  }

  // We only see the view for fractions of a second before we are redirected home
  return view('sample.confirmUser', compact('user', 'cvId'));
}
