Auth ::尝试在Laravel护照api上不起作用

Question

这是我的登录尝试：

public function loginUser(Request $request){
   $rules = [
       'email' => 'required',
       'password' => 'required'
   ];
   $this->validate($request, $rules);
   //attempting login
   if(Auth::attempt(['email' => $request->email, 'password' => $request->password])){
    return 'hello';
   }
   return 'null';

}

这是我的身份验证配置：

'guards' => [
    'web' => [
        'driver' => 'session',
        'provider' => 'users',
    ],

'api' => [
    'driver' => 'passport',
    'provider' => 'users',
    //'hash' => false,
],
],

'providers' => [
'users' => [
    'driver' => 'eloquent',
    'model' => App\Models\User::class,
],

// 'users' => [
//     'driver' => 'database',
//     'table' => 'users',
// ],
],

这是我的数据结构：

 Schema::create('users', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->string('email')->unique();
        $table->integer('verified')->unsigned();
        $table->string('verification_token')->nullable();
        $table->timestamp('email_verified_at')->nullable();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });

当我从我的api路由调用此loginUser函数时，即使我传递的凭据有效，它也会为我提供null； 而且我正在使用bcrypt密码；
