Question

我正在一个Laravel管理面板上，当我输入凭证时，该面板会循环回到管理面板。目标是导航到控制台。 Laravel版本是7倍。我正在从localhost / xampp处理它。我仔细检查了相关文件 env ， database.db 中的数据库连接。它使数据库进入phpmyadmn。预先感谢您的建议

Answer 1

我发现您的问题出在password列中，因为它没有哈希值：

散列值似乎有点像这样：$2y$10$ZQcgqgmFuqwQcZW7GYQsR.KmGxmw6mXDCwyKRHksw039IhU34A49W

解决方案：

检查用于注册管理员的方法。无论是播种机还是任何其他过程，请验证其是否具有调用以下方法对密码字符串

进行哈希处理的方法

 Hash::make($data['password'])

因此在执行本节时：

   Auth::guard('admin')->attempt([
    'email' => $request->email,
    'password' => $request->password]);

将通过email列的值检索用户。如果找到用户，则将存储在数据库中的哈希密码与通过数组传递给该方法的密码值进行比较。

有关更多详细信息，请查看：https://laravel.com/docs/7.x/authentication#included-authenticating

我希望这会有所帮助。谢谢。

Answer 2

我不知道为什么会这样，但是我认为laravel由于使用admin.php路由存在问题而感到困惑，

我建议您使用这段代码

    Route::group(['middleware' => ['auth:admin']], function () {

    Route::get('/admin', function () {
        return view('admin.dashboard.index');
    })->name('admin.dashboard');

});

并将其放在web.php中，并将其从routes/admin.php中删除请注意，我在代码中添加了'/admin'，以便指向/ admin的所有内容都可以正常工作希望此帮助无法奏效，请及时通知我

尽管凭据正确，Laravel 7X管理员/登录也会循环回到管理员/登录
