Question

我使用的是Yii2高级版。

这是登录模型：

namespace common\models;
use Yii;
use yii\base\Model;
use common\models\User;

class LoginForm extends Model{  
    public $username;
    public $password;
    public $rememberMe = true;
    public $verifyCode;

    const BACKEND_TEST = 'none';
    const BACKEND_ID = 'test';
    const BACKEND_USERNAME = 'backend_username';

    private $user;

    public function rules(){
        return [            [['username','password'],'required','message'=>'{attribute}required...'],
['username','validateUser'],          ['verifyCode','captcha','captchaAction'=>'login/captcha','message'=>'Wrong'],
            ];
    }

    public function validateUser($attribute,$params){
        $user = User::findOne(['username'=>$this->username]);
        if(!$user || (md5($this->password) != $user['password'])){
            $this->addError('password','Wrong>_<...');
        }else{
        $this->user = $user;
        }
    }

    public function login(){
        if(!$this->user){
            return false;
        }
        var_dump($this->userInfo());
        $this->createSession();
        return true;

    }

    private function createSession(){
        //Yii::$app->session->open();
        Yii::$app->set(self::BACKEND_ID,$this->user['id']);
        Yii::$app->set(self::BACKEND_USERNAME,$this->user['username']);

    }
public function userInfo(){
    return $this->user;
}

另外，我认为有一个LoginController没有问题，接下来就是当用户尝试登录时会打开会话并直接进入网站页面。这是sitecontroller：

namespace backend\controllers;

use Yii;
use yii\web\Controller;
use yii\filters\VerbFilter;
use yii\filters\AccessControl;
use common\models\LoginForm;

/**
 * Site controller
 */
class SiteController extends Controller
{

    public function actionIndex()
    {
        //var_dump(Yii::$app->session->get(common\models\LoginForm::BACKEND_ID));
        var_dump(LoginForm::userInfo());
        return $this->renderPartial('index');
    }

每次我尝试登录并出现错误消息并提供：

无效配置 - yii \ base \ InvalidConfigException

“test”组件的意外配置类型：整数

如何解决问题，我尝试获取存储所有数据的$ user，但似乎失败了？

main.php：

<?php
$params = array_merge(
    require(__DIR__ . '/../../common/config/params.php'),
    require(__DIR__ . '/../../common/config/params-local.php'),
    require(__DIR__ . '/params.php'),
    require(__DIR__ . '/params-local.php')
);

return [
    'id' => 'app-backend',
    'basePath' => dirname(__DIR__),
    'controllerNamespace' => 'backend\controllers',
    'bootstrap' => ['log'],
    'modules' => ['smister' => [
            'class' => 'backend\modules\smister\smister',
        ],],
    'components' => [
        'user' => [
            'identityClass' => 'common\models\User',
            'enableAutoLogin' => true,
        ],
        'log' => [
            'traceLevel' => YII_DEBUG ? 3 : 0,
            'targets' => [
                [
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['error', 'warning'],
                ],
            ],
        ],
        'errorHandler' => [
            'errorAction' => 'site/error',
        ],
        /*
        'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
            ],
        ],
        */
    ],
    'params' => $params,
];

您正在使用

 Yii::$app->set(self::BACKEND_ID,$this->user['id']);

可能用于设置参数值.. 但是类yii \ web \ Application（别名Yii :: $ app-＆gt; set）包含一个名为set（）的函数来注册组件..（所以你的错误：＆＃34; test＆＃34的意外配置类型;组件：整数）这样你的代码被Yii2误解了，因为你的costant BACKEND_ID =＆＃39; test＆＃39 ;;不是组件ID，而是param的关键

请参阅此参考资料

http://www.yiiframework.com/doc-2.0/yii-web-application.html

http://www.yiiframework.com/doc-2.0/yii-di-servicelocator.html#set()-detail

对于您的范围，如果您需要param，则可以使用文件param.php

返回你需要的参数

file config / param.php

<?php
   return [
     'test' => 'my_initial_value',
];

您只需使用

即可访问此参数

 \Yii::$app->params['test'],

或者您可以简单地设置运行时

  \Yii::$app->params['test'] = 'Your_value';

Yii2：无法处理获取Session
