问题描述

我正在使用Laravel 5并收到以下异常:

I am using Laravel 5 and getting the following exception:

PDOException(1044)SQLSTATE [HY000] [1044]用户的访问被拒绝 " @"localhost"到数据库"forge"

PDOException (1044) SQLSTATE[HY000] [1044] Access denied for user ''@'localhost' to database 'forge'

我的数据库配置文件是:

My database configuration file is:

我该如何解决?

推荐答案

在根目录中放置一个.env文件，并将此代码粘贴到此处.

Put a .env file in your root directory and paste this code there.

APP_ENV=local
APP_DEBUG=true
APP_KEY=1CaND3OKKvOGSBAlCg6IyrRmTQWwZjOO

DB_HOST = localhost
DB_DATABASE = YOUR_DATABASE_NAME
DB_USERNAME = USER_NAME
DB_PASSWORD = PASSWORD

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

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

在此处更新您的数据库，用户名和密码字段，它应该可以解决您的问题.在您的配置文件中，env()函数从此处查找此文件和变量.

Update your database, username and password field here and it should solve your problem. In your configuration file env() function is looking for this file and variables from here.

更新:在运行应用程序或迁移之前，您必须创建一个空白数据库.

UPDATE: You must create a blank database before running the app or migration.
