yii2中restful url访问配置， 登陆接口access-token验证类

登陆接口access-token验证类
Controller下新建BaseActiveController.php

<?php
/**
 *接口登陆验证
 * @author 爱博
 * 1.0
 *
 */
namespace backendcontrollers;

use yiifiltersauthCompositeAuth;
use yiifiltersauthHttpBasicAuth;
use yiifiltersauthHttpBearerAuth;
use yiifiltersauthQueryParamAuth;
use yiifiltersCors;
use yiifiltersRateLimiter;
use yiirestController;
use Yii;

class BaseActiveController extends Controller
{
    public $modelClass = "commonmodelsuser";

    public $post = null;
    public $get = null;
    public $user = null;
    public $userId = null;

    public function init()
    {
        parent::init();

        Yii::$app->user->enableSession = false;
    }

    public function behaviors()
    {
        $behaviors = parent::behaviors();

        $behaviors["authenticator"] = [
            "class" => CompositeAuth::className(),
            "authMethods" => [
           //     HttpBasicAuth::className(),
           //     HttpBearerAuth::className(),
                QueryParamAuth::className(),
            ],
        ];

      
      //  数据返回类型设置
        //$behaviors["contentNegotiator"]["formats"]["application/json"] = "json";
       //$behaviors["contentNegotiator"]["formats"]["application/xml"] = "json";
    
        return $behaviors;
    }


    public function beforeAction($action)
    {
        parent::beforeAction($action);

        $this->post = yii::$app->request->post();
        $this->get = yii::$app->request->get();
        $this->user = yii::$app->user->identity;
        $this->userId = Yii::$app->user->id;

        return $action;
    }


} 

下边新建 UserController.php

<?php
namespace backendcontrollers;
use Yii;
use yiifiltersauthCompositeAuth;
use yiifiltersauthQueryParamAuth;
use yiidataActiveDataProvider;
use yiihelpersJson;
use commonmodelsLoginForm;

class UserController extends BaseActiveController
{
    /**
     * 判断用户登录信息，并返回结果。
     * @author   <sang.jiyu>
     */
    public function actionIndex()
    {
        if(Yii::$app->user->isGuest){
            $data=array(
                "code"=>100,
                "message"=>"用户未登录",
                "data"=>"",
            );
        }else{
            $data=array(
                "code"=>200,
                "message"=>"用户已经登录",
                "data"=>array(
                    "user_id"=>Yii::$app->user->id,
                    "user_name"=>isset(Yii::$app->user->identity->username) ? Yii::$app->user->identity->username : "",
                ),
            );
        }
        echo json_encode($data);exit;
    }

}

目录common/models下新建 User.php

<?php
namespace commonmodels;

在新建LoginForm.php

<?php
namespace commonmodels;

use Yii;
use yiibaseModel;

/**
 * Login form
 */
class LoginForm extends Model
{
    public $username;
    public $password;
    public $rememberMe = true;

    private $_user;


    /**

    public function rules()
    {
        return [
            // username and password are both required
            [["username", "password"], "required"],
            // rememberMe must be a boolean value
            ["rememberMe", "boolean"],
            // password is validated by validatePassword()
            ["password", "validatePassword"],
        ];
    }

    /**

     * This method serves as the inline validation for password.
     *
     * @param string $attribute the attribute currently being validated
     * @param array $params the additional name-value pairs given in the rule
     */
    public function validatePassword($attribute, $params)
    {
        if (!$this->hasErrors()) {
            $user = $this->getUser();
            if (!$user || !$user->validatePassword($this->password)) {
                $this->addError($attribute, "Incorrect username or password.");
            }
        }
    }

    /**
     * Logs in a user using the provided username and password.
     *
     * @return bool whether the user is logged in successfully
     */
    public function login()
    {
        if ($this->validate()) {
            return Yii::$app->user->login($this->getUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);
        } else {
            return false;
        }
    }

    /**
     * Finds user by username
     *
     * @return User|null
     */
    protected function getUser()
    {
        if ($this->_user === null) {
            $this->_user = User::findByUsername($this->username);

        return $this->_user;
    }
}

http://localhost/yii2/backend/web/index.php?r=user/index&access-token=rMwh_EnqAc0qEPTfzb66BlGtSqoF15sg
没有作美化，大家自己处理一下吧，注意这个rMwh_EnqAc0qEPTfzb66BlGtSqoF15sg内容为数据库里的access-token这个内容里的值
返回内容为

{"code":200,"message":"u7528u6237u5df2u7ecfu767bu5f55","data":{"user_id":"1","user_name":"terry"}}

返回这个内容就成功了

下边完成登陆用户名和密码验证生成access-token的内容
在controllers这个目录下新建SiteController.php

<?php
/**
* 
*登陆接口access-token验证类
* @author 爱博
* 1.0
*
*
*/

namespace backendcontrollers;

use Yii;
use backendmodelsformsLoginForm;
use commonlibHelper;
use yiibaseException;
use yiibaseInvalidValueException;
use yiibaseUserException;
use yiiwebErrorAction;
use yiiwebHttpException;
use yiirestController;

class SiteController extends Controller
{

    public $modelClass = "commonmodelsuser";
    public function behaviors()
    {
       $behaviors = parent::behaviors();
       // unset($behaviors["authenticator"]);
        return $behaviors;
    }

    protected function verbs()
    {
        $verbs = parent::verbs();
      //  $verbs["index"] = ["POST"];
        return $verbs;
    }

    public function actionLogin()
    {

        $loginModel = new LoginForm();
        $loginModel->load([$loginModel->formName() => yii::$app->request->get()]);

         if ($loginModel->validate()) {
            $rs = $loginModel->login();
     
            return Helper::format_data($rs);
        } else {
            return Helper::format_data($loginModel->getErrors(), HTTP_STATUS_401);
        }
    }
}

运行http://localhost/yii2/backend/web/index.php?r=site/login&password=rasmuslerdorf&username=terry

Use of undefined constant HTTP_STATUS_200 - assumed "HTTP_STATUS_200"

返回这个内容就成功了
