Laravel10 简单使用 Auth 生成 Token 与登录并获取用户信息

参考

环境

前置工作

https://learnku.com/docs/laravel/10.x/sanctummd/14914#installation

1. 安装 composer require laravel/sanctum
2. 发布配置与迁移文件 php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"
3. 将 Sanctum 的中间件添加到你的应用程序的 app/Http/Kernel.php 文件中的 api 中间件组中

   'api' => [
   \Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful::class,
      \Illuminate\Routing\Middleware\ThrottleRequests::class.':api',
      \Illuminate\Routing\Middleware\SubstituteBindings::class,
   ],
   

4. 数据库迁移 php artisan migrate (需要数据库链接)

完整代码 api.php

获取的令牌放在 Authorization 标头中传递，格式为 Bearer ${token}, 其中 token 为获取到的登录 token 字符串，如Bearer 6|Qyl8iYbMVf1eJOgPvfskxinNC8MnOwrnEf66RgoG

<?php

use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Route;
use Illuminate\Validation\ValidationException;

// 使用 middleware('auth:sanctum') 包裹的就会自定验证用户登录与将用户信息放到 $request->user() 中
// 获取的令牌放在 Authorization 标头中传递，格式为 `Bearer ${token}`, 其中 token 为获取到的登录 token 字符串，如`Bearer 6|Qyl8iYbMVf1eJOgPvfskxinNC8MnOwrnEf66RgoG`
Route::middleware('auth:sanctum')->prefix("/user")->group(function () {
    Route::get('', function (Request $request) {
        return [
            // 所有token
            // $request->user()->tokens
            // 
            $request->user()
        ];
    });
    Route::delete('/login_out_all', function (Request $request) {
        return $request->user()->tokens()->delete();
    });
});

// 添加用户
Route::post('/add_user', function (Request $request) {
    // 密码版
    $user = new User();
    $user->name = $request->input("name");
    $user->email = $request->input("email");
    // 需要通过 Hash::make 加密后，才能使用 Auth::attempt 验证密码正确性
    $user->password = Hash::make($request->input("password"));
    $user->save();
    // // 小程序版
    // $user               = new User();
    // $user->phone_number = $request->input("phone_number");
    // // openId 需要去微信获取，这里只是简单演示
    // $user->open_id      = $request->input("open_id");
    // $user->save();

    return $user;
});
// 用户登录
Route::post('/login_user', function (Request $request) {
    // // 密码版验证
    $email      = $request->input("email");
    // password 为未加密的用户密码，如：123456
    $password   = $request->input("password");
    // 可以添加自定义认证字段，如：active=1
    // if (Auth::attempt(['email' => $email, 'password' => $password, 'active' => 1])) {
    if (!Auth::attempt(['email' => $email, 'password' => $password])) {
        throw new \Exception("用户验证失败");
    }
    // 通过验证后就会自动登录，$request->user() 就可以获取到用户信息了。
    return [
        'token' => $request->user()->createToken("USER_TOKEN"),
        'user'=> $request->user()
    ]; 
    // // 密码版验证 结束

    
    // // 小程序版验证
    // $user = User::where("email", $request->input("email"))->firstOrFail();
    // Auth::login($user);
    // $token = $request->user()->createToken("USER_TOKEN");
