Auth::login() 在 Laravel 8 中不起作用

Question

Auth::login() 无效。在做这个项目之前，我做了另一个然后就成功了。这是用户模型

<?php

namespace App\Models;

use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class User extends Model implements Authenticatable
{
    use \Illuminate\Auth\Authenticatable;

    use HasFactory;
}

这是我的登录控制器：

function loggedIn(Request $request){
       echo $name = $request['name'];
        $password = $request['password'];
        $user = User::where([
            ["name", $name],
            ["password", $password],
        ])->get()->first();

        if ($user != ''){
            Auth::login($user);
            return redirect()->route('welcome');

        }else{
            return redirect()->back()->with(['error'=>'Ismingiz tasdiqlanmadi!']);
        }

    }

控制器重定向欢迎路由，但欢迎路由再次将其重定向到登录页面。路由 welcome 有中间件 auth:

Route::get('/', function () {
    return view('welcome');
})->name('welcome')->middleware('auth');

如果你有解决办法，请告诉我！

正如 onlie Thomas 在评论中写道：

try to create a smaller example for yourself and see where things start to no longer work. I would suggest stop echo-ing like in loggedIn because this disrupts some functions in Laravel. for example bacause: >Remember that header() must be called before any actual output is sent

我的错误，我在header()函数之前写了echo；
