$request->user (‘admin’) 获取用户信息时 返回 NULL

请求头加上token了吗

这个是必须请求头有token才能获取到吗

App\Models\Admin::class，我看一下

<?php

namespace App\Models;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Passport\HasApiTokens;
use Spatie\Permission\Traits\HasRoles;

class Admin extends Authenticatable
{
    use Notifiable, HasApiTokens, HasRoles;

    /**
     * 平台管理员数据表
     */
    protected $table = 'admins';

    /**
     * 守卫
     */
    protected $guard_name = 'admin';
}

贴一下登录代码，登录的时候要用admin的guard才行，目测是因为你没用，所以用了默认的default guard web

@FMW

    public function login(LoginRequest $request)
    {
    try {
        $credentials = $request->validated();

        if(!Auth::guard('admin')->attempt($credentials))
        return $this->failed('用户名或密码错误！');

        $user = $request->user();

        $tokenResult = $user->createToken($user->name . ' Personal Access Token');

        return $this->success([
        'access_token' => $tokenResult->accessToken,
        'token_type' => 'Bearer',
        ]);
    } catch (\Exception $e) {
        report($e);
        return $this->failed('错误代码：40002');
    }
    }

你用的passport啊，那必须要带有Authorization的头才行，还有你这里登录怎么就直接从$request获取用户了，你这是要获取web guard的登录用户？那你还判断密码干什么？

@Liuzhipeng_laravel 你这么一说还真是，guard对passport是无效的，源码里面是直接写死了获取api的guard

// /vendor/laravel/passport/src/Bridge/UserRepository.php
public function getUserEntityByUserCredentials($username, $password, $grantType, ClientEntityInterface $clientEntity)
{
    // 这里写死了获取api这个guard，所以你写的admin是没有用的
    $provider = config('auth.guards.api.provider');

    if (is_null($model = config('auth.providers.'.$provider.'.model'))) {
        throw new RuntimeException('Unable to determine authentication model from configuration.');
    }

    if (method_exists($model, 'findForPassport')) {
        $user = (new $model)->findForPassport($username);
    } else {
        $user = (new $model)->where('email', $username)->first();
    }

    if (! $user) {
        return;
    } elseif (method_exists($user, 'validateForPassportPasswordGrant')) {
        if (! $user->validateForPassportPasswordGrant($password)) {
            return;
        }
    } elseif (! $this->hasher->check($password, $user->getAuthPassword())) {
        return;
    }

    return new User($user->getAuthIdentifier());
}
