当我将 MySQL 连接添加到我的 laravel 安装时，它似乎不起作用。我仔细检查了每个设置，也在远程服务器上。凭据是正确的，一切都应该有效。下面我将发布我的 Controller 、 View 和 database.config 文件，这样您就可以看到哪里出了问题。在过去的 2 个小时里，我一直在尝试解决这个问题，但我不知道出了什么问题:( 当我测试是否有数据时，它没有说该表不存在，它只是返回 null。(我确实有选择权限)
Controller
<?php
namespace App\Http\Controllers;
use DB;
use App\Log;
class DataController extends Controller
{
public function index()
{
$logs = Log::distinct()->select(['device_name','device_id'])->get();
return view('data.index', compact('logs'));
}
public function show($device_id)
{
$logs = DB::table('datalog_net_data')->take(100);
return view('data.show', compact('logs'));
}
public function dashboard()
{
$pageTitle = "Dashboard";
return view('data.dashboard', compact('pageTitle'));
}
}

最佳答案
更改 .env 文件中的 DB_HOST:
DB_HOST=localhost
到
DB_HOST=127.0.0.1
