YI2HTTPBasic认证RESTful API (Yii 2高级模板)

Question

REST在没有身份验证方法的情况下工作。现在，我想通过移动应用程序使用HTTP基本身份验证API请求来验证REST。我试过使用yii2指南，但它对我没有用。

基本上，移动用户需要使用用户名和密码登录，如果用户名和密码是正确的，用户需要登录，进一步的API请求需要用令牌进行验证。

调试findIdentityByAccessToken()函数时，$token等于用户名。用于检查HTTP基本请求的Postman扩展。用户表中的access_token字段为空。我需要手动保存它吗？如何返回access_token作为响应？

有理由同时使用三种方法(HttpBasicAuth、HttpBearerAuth、QueryParamAuth)吗?为什么？多么?

我的应用程序文件夹结构如下所示。

api
-config
-modules
--v1
---controllers
---models
-runtime
-tests
-web

backend
common
console
environments
frontend

api\modules\v1\Module.php

namespace api\modules\v1;
class Module extends \yii\base\Module
{
    public $controllerNamespace = 'api\modules\v1\controllers';

    public function init()
    {
        parent::init(); 
        \Yii::$app->user->enableSession = false;       
    }   
}

api\modules\v1\controllers\CountryController.php

namespace api\modules\v1\controllers;
use Yii;
use yii\rest\ActiveController;
use common\models\LoginForm;
use common\models\User;
use yii\filters\auth\CompositeAuth;
use yii\filters\auth\HttpBasicAuth;
use yii\filters\auth\HttpBearerAuth;
use yii\filters\auth\QueryParamAuth;

class CountryController extends ActiveController
{
    public $modelClass = 'api\modules\v1\models\Country';    

    public function behaviors()
    {
        $behaviors = parent::behaviors();
        $behaviors['authenticator'] = [
            'class' => HttpBasicAuth::className(),
            //'class' => CompositeAuth::className(),
            // 'authMethods' => [
            //     HttpBasicAuth::className(),
            //     HttpBearerAuth::className(),
            //     QueryParamAuth::className(),
            // ],
        ];
        return $behaviors;
    }

}

common\models\User.php

namespace common\models;

use Yii;
use yii\base\NotSupportedException;
use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\web\IdentityInterface;

class User extends ActiveRecord implements IdentityInterface
{
    const STATUS_DELETED = 0;
    const STATUS_ACTIVE = 10;

    public static function tableName()
    {
        return '{{%user}}';
    }

    public function behaviors()
    {
        return [
            TimestampBehavior::className(),
        ];
    }

    public function rules()
    {
        return [
            ['status', 'default', 'value' => self::STATUS_ACTIVE],
            ['status', 'in', 'range' => [self::STATUS_ACTIVE, self::STATUS_DELETED]],
        ];
    }

    public static function findIdentity($id)
    {
        return static::findOne(['id' => $id, 'status' => self::STATUS_ACTIVE]);
    }

    public static function findIdentityByAccessToken($token, $type = null)
    {

        return static::findOne(['access_token' => $token]);
    }


}

用户表

id
username
auth_key
password_hash
password_reset_token
email
status
created_at
access_token

迁移用户表后添加了access_token

您需要在保存用户之前设置令牌。在用户模型中，使用以下内容

public function beforeSave($insert)
{
    if (parent::beforeSave($insert)) {
        if ($this->isNewRecord) {
            $this->auth_key = Yii::$app->getSecurity()->generateRandomString();
        }
        return true;
    }
    return false;
}

现在您为每个用户提供了一个auth_key

要返回auth_key，需要在UserController中添加actionLogin

public function actionLogin()
{
    $post = Yii::$app->request->post();
    $model = User::findOne(["email" => $post["email"]]);
    if (empty($model)) {
        throw new \yii\web\NotFoundHttpException('User not found');
    }
    if ($model->validatePassword($post["password"])) {
        $model->last_login = Yii::$app->formatter->asTimestamp(date_create());
        $model->save(false);
        return $model; //return whole user model including auth_key or you can just return $model["auth_key"];
    } else {
        throw new \yii\web\ForbiddenHttpException();
    }
}

之后，在每个API请求中，您都会在头中发送auth_key，而不是发送用户名和密码。

$ curl -H "Authorization: Basic bd9615e2871c56dddd8b88b576f131f51c20f3bc" API_URL

若要检查auth_key是否有效，请在UserController行为中定义“身份验证器”。(不要忘记将“创建”、“登录”、“重新设置密码”排除在身份验证之外)

public function behaviors()
{
    return ArrayHelper::merge(
        parent::behaviors(), [
            'authenticator' => [
                'class' => CompositeAuth::className(),
                'except' => ['create', 'login', 'resetpassword'],
                'authMethods' => [
                    HttpBasicAuth::className(),
                    HttpBearerAuth::className(),
                    QueryParamAuth::className(),
                ],
            ],
        ]
    );
}
