Question

我正在处理身份验证模块，我有以下代码，if条件是检查表单字段不起作用且条件为false。

然后else消息也没有在那里显示。

if (Auth::attempt(['email' => Input::get("email"), 'password' => Input::get("password")], true)) {

  return redirect()->intended('dashboard');

} else {
  return redirect()
        ->back()
        ->with('message', 'Incorrect email or password.')
        ->with('form', 'login')
        ->withInput(Input::except('password'));
}

在登录视图中，我有一大堆错误代码：

<div class="alert alert-danger {{{ (Session::has('message') && Session::get('form', 'login') == 'login') ? '' : 'display-hide' }}}">
    <button class="close" data-close="alert"></button>
    <span>
        {!! Session::has('message') ? Session::get('message') : 'Please correct your fields.' !!}
    </span>

</div>

Answer 1

这不起作用，因为auth :: attempt使用bcrypt将密码转换为hash，并在users表中查找该hash以匹配。

简而言之，密码应该是存储在数据库表中的哈希值，用于auth ::尝试工作。

这就是你的if（）条件失败的原因。

以下是来自laravel 5.2 docs

laravel.com/docs/5.2/authentication#authenticating-users

attempt方法接受一个键/值对数组作为其第一个   论点。数组中的值将用于查找用户   你的数据库表。因此，在上面的示例中，用户将是   通过电子邮件列的值检索。如果找到用户，则   存储在数据库中的哈希密码将与之进行比较   散列密码值通过数组传递给方法。如果是两个   将启动散列密码匹配经过身份验证的会话   用户。

如果身份验证成功，则尝试方法将返回true。   否则，将返回false。

Laravel：将数据传递给session和auth :: attempt
