thinkphp教程之RBAC详解4之权限校验

权限校验部分
新建CommonAction类文件，写入以下代码

<?php

class CommonAction extends Action{

//初始化方法，调用方法时会先执行

function _initialize(){

    header('Content-Type:text/html;charset=utf-8');

        import('ORG.Util.Cookie');

        // 用户权限检查

        if (C('USER_AUTH_ON') && !in_array(MODULE_NAME, explode(',', C('NOT_AUTH_MODULE')))) {

            import('ORG.Util.RBAC');

            if (!RBAC::AccessDecision()) {

                //检查认证识别号

                if (!$_SESSION [C('USER_AUTH_KEY')]) {

                    //跳转到认证网关

                    redirect(PHP_FILE . C('USER_AUTH_GATEWAY'));

                }else{

                    echo L('_VALID_ACCESS_');

                    exit();

                }

                // 没有权限 抛出错误

                if (C('RBAC_ERROR_PAGE')) {

                    // 定义权限错误页面

                    redirect(C('RBAC_ERROR_PAGE'));

                } else {

                    if (C('GUEST_AUTH_ON')) {

                        $this->assign('jumpUrl', PHP_FILE . C('USER_AUTH_GATEWAY'));

                    }

                    // 提示错误信息

                    $this->error(L('_VALID_ACCESS_'));

                }

            }

        }

}
