Question

我继续别人的代码。并且一直试图解决它。

它是一个使用laravel的运行系统。然后我将系统移动到另一台计算机。

我设法在此guide之后使用xampp进行设置但在我登录后，它一直给我无效登录。香港专业教育学院检查数据库，凭证是否正确。

我真的不知道如何追踪它出错的地方，但我设法得到这个痕迹（我更改了数据库名称）;密码丢失了。

错误名称

PDOException in PDOConnection.php line 43:
SQLSTATE[HY000] [1044] Access denied for user ''@'localhost' to database 
'myapp'

错误是由于我更改了db用户名。 ;）我试图弄清楚为什么当它移动到另一台机器时它不起作用。如果散列密码隐藏在跟踪中，我猜我所分享的跟踪将没有任何帮助。任何想法我接下来应该做什么？：_I

更新的LoginController

更新按要求登录LoginController.php

    return redirect()->intended($this->redirectPath());
}


}

更新2

<form class="form-horizontal" role="form" method="POST" action="{{ route('mem.lPost') }}"> {{ csrf_field(=) }}

Answer 1

确保在.env文件中正确指定了数据库服务器的用户名和密码。在您的错误中，似乎您将用户名设置为“”，因此它表示拒绝访问用户''@ localhost'。编辑.env文件

DB_DATABASE=yourDBname
DB_USERNAME=root (or whatever your usrname), there is no possibly here to be null
DB_PASSWORD=yourpassword

Answer 2

如果您正在使用<div class="row form-group m-form__group m-login__form-sub"> <div class="col m--align-left"> <?php echo $this->Form->input('agree', array( 'type'=>'checkbox','label'=>'I Agree The'));?> <a href="#" class="m-link m-link--focus">terms and conditions</a> </div>，请检查您的配置文件或.env文件。输入正确的凭据，您就可以了。尝试使用默认设置：

laravel 5.*

<强>更新

如果您更改了应用程序的db database = myapp username = password = root host = localhost，那么存储在数据库中的加密数据将不再有效，例如app key，除非您将passwords放回原处。因此，帐户的解决方案是使用app key帮助程序或bcrypt创建或更新密码，以便Hash::make能够正确存储新的passwords。

注意： 您可以将它放在您的主页方法所在的控制器中。

Answer 3

将项目复制到新系统
通过终端
运行命令“php artisan key：generate”
设置.env文件
设置您的用户名，密码和数据库名称
重新启动apache2（$ sudo service apache2 restart - 如果它的ubundu 14）

示例环境文件

APP_ENV=local
APP_DEBUG=true
APP_KEY=SomeRandomString
APP_URL=http://localhost

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=yourDB
DB_USERNAME=root
DB_PASSWORD=yourpassword

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
