Auth::attempt [Laravel] 效果不好，总是返回 false

Question

每次我尝试测试我的 TestLogin 函数时，它都会返回 false，无论我的输入是不正确的[未存储在数据库中]还是正确的[存储在我的数据库中]...

auth.phph 的配置更正 ['model' => 'User'&& 'table' => 'users']

请在此处提供任何帮助:)

    $data = Input::All();                     //Get Input with POST Request
    $UNameOrEmail = $data['UnameOrEmail'];
    $password = $data['Password'];

    if(filter_var($UNameOrEmail, FILTER_VALIDATE_EMAIL)) {      //Check if Input Is Email or else(then consider it as user name)

        $validator = Validator::make(           //Validation for Email

Answer 1

我可以看到您使用的是 Input::All()（大写 A），而不是 Input::all()。

做一个dd(Input::All()); 看看它返回什么。

发现问题（我认为）：您应该不散列您的密码，因为 Auth 会自动执行此操作。简而言之，您手动对其进行哈希处理，然后 Auth 再次对其进行哈希处理，这就是为什么密码永远不会与数据库表中存储的内容匹配的原因:)

Answer 2

在将密码传递给Auth::attempt 之前，您不得散列密码。只需传递普通密码：

$user = array(                           
    'user_name' => $UNameOrEmail,
    'password' => $password
);

还要确保将密码的哈希值存储在数据库中，并且密码字段的长度为 60 个字符。否则哈希将被截断，它不会工作。
