Question

我已经为我的laravel项目完成了db配置，但它给出了一个错误说明 SQLSTATE [HY000] [1045]拒绝访问用户＆＃39; homestead＆＃39; localhost＆＃39; （使用密码：是）（SQL：select * from users其中user_name =管理员限制1）

但我已经修改了我的dbname和密码，上面显示的内容不正确。这是我的登录控制器

<?php 
namespace App\Http\Controllers;
use Illuminate\Support\Facades\Input;
use App\Login;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Redirect;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Schema;
class LoginController extends Controller {
    public function login(){
        $uname = Input::get('username');
        $pwd = Input::get('password');
        if (Auth::attempt(array('user_name' => $uname, 'password' => $pwd))){
            return "success";
        }
        else {
            return "Wrong Credentials";
        }    
     }
}

这是我的.env

APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:Zm3uZ82dtjozo68rs2cGAlXXmzj9EuueqCcKsC73VTo=

我的config / database.php如下

Answer 1

由于您的.env看起来不错，我假设您正在使用php artisan serve将您的网站置于在线状态以进行本地主机测试。

如果您在serve运行时进行了这些更改，则不会注册直播方。只需停止artisan serve运行，然后再次运行它，更改将生效。

如何在laravel中连接我的sql？
