Question

我是PHP和Laravel的新手。我正在关注LaraCast教程，它创建了一个简单的用户表。然后路由功能获取所有用户并返回浏览器。我可以在数据库中看到数据，但结果总是通过Laravel路由为空。创建db，table等后是否需要重新启动任何内容？谢谢你的帮助。

routes.php文件

Route::get('/', function(){
    $users = DB::table('users')->get();

    return $users;
});

database.php中

'mysql' => array(
            'driver'    => 'mysql',
            'host'      => '127.0.0.1',
            'database'  => 'awesomeproject',
            'username'  => 'homestead',
            'password'  => '***',
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
        ),

当我点击http://awesome.app:8000/时，我得到[]作为回复。

MySQL的

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| awesomeproject     |
| homestead          |
| mysql              |
| performance_schema |
+--------------------+
5 rows in set (0.00 sec)

mysql> use awesomeproject
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed

mysql> show tables;
+--------------------------+
| Tables_in_awesomeproject |
+--------------------------+
| users                    |
+--------------------------+
1 row in set (0.00 sec)

mysql> select * from users;
+----------+---------------+
| username | password      |
+----------+---------------+
| ulidder  | skjdfsjkhsdfs |
| user2    | dslfjasdfhw   |

Answer 1

debug中true设置为config/local/app.php吗？

确保您检查app/config/local/database.php中的连接凭据，而不是app/config/database.php。如果您使用的是Homestead，那么app/config/local/database.php应该是这样的：

'mysql' => array(
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => 'homestead',
    'username'  => 'homestead',
    'password'  => 'secret',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),

如果您未在app/config/local/database.php中设置凭据，则当您认为正在查询homestead数据库时，可能会从awesomeproject数据库中提取结果。

Laravel db：table（）返回空集
