Yii 2 RESTful API使用HTTP Basic进行身份验证(Yii 2高级模板)

REST API无需身份验证方法即可运行。现在,我想通过移动应用程序对API请求进行HTTP基本身份验证来验证REST API。我试过yii2指南,但它对我没用。

基本上移动用户需要使用用户名&密码,如果用户名和密码正确,则用户需要登录,并且需要使用令牌验证进一步的API请求。

当我调试findIdentityByAccessToken()函数时,$ token等于用户名。 Postman扩展用于检查HTTP Basic请求。 用户表中的access_token字段为空。我需要手动保存吗? 如何将access_token作为响应返回?

是否有任何理由同时使用所有三种方法(HttpBasicAuth,HttpBearerAuth,QueryParamAuth),为什么?怎么样?

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 \模块\ 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 \模块\ V1 \控制器\ 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;
    }

}

常见\模型\ user.php的

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。在用户模型中使用此

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

现在每个用户都有一个auth_key

返回auth_key,你需要在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,您都会在标头中发送auth_key,而不是发送用户名和密码

$ curl -H "Authorization: Basic bd9615e2871c56dddd8b88b576f131f51c20f3bc" API_URL

检查auth_key是否有效,在UserController行为中定义'authenticator'。 (不要忘记从身份验证中排除'create','login','resetpassword')

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