如何指定要绑定到CWebUser的name属性的用户表中的哪个字段?

在您的配置中

// application components
    'components'=>array(
        'user'=>array(
            // enable cookie-based authentication 
            'allowAutoLogin'=>true,
            'class'=>'WebUser',
        ),

WebUser类(例如表“user”中的“email”字段):

  class WebUser extends CWebUser
    {
        public function getEmail() 
        {    
            if(!$this->getState('__email')&&$this->id)
            {
                $user = User::model()->findByPk($this->id);
                $this->setState('__email', $user->email);
            }
            $state = $this->getState('__email');
            return $state;
        }

        public function login($identity, $duration=0) 
        {
            $this->allowAutoLogin = true;
            parent::login($identity, $duration);
            $this->id = $identity->id;
            if (!$this->isGuest)
            {
                if($user = User::model()->findByPk($this->id))
                {
                    $this->setState('__email', $user->email);
                }
            }
        }
    }

您应该通过扩展CUserIdentity来编写自己的UserIdentity组件,并在用户标识声明$this->之后的authenticate()方法中;用户名=$user->变量
