配置定时任务只能当前服务器调用

在定时任务所在的类的初始化方法中，添加ip判断

protected function _initialize() {
 
      //获取访问该类的ip
      if (getenv("HTTP_CLIENT_IP"))
          $ip = getenv("HTTP_CLIENT_IP");
      else if(getenv("HTTP_X_FORWARDED_FOR"))
          $ip = getenv("HTTP_X_FORWARDED_FOR");
      else if(getenv("REMOTE_ADDR"))
          $ip = getenv("REMOTE_ADDR");
      else $ip = "Unknow";
 
      //允许访问的ip
      $ALLOWED_IP=array('10.66.206.65','192.168.1.5');
       
      //等待检查的ip地址
      $check_ip_arr= explode('.',$ip);
       
      //ip参数拆分成数组
      if(!in_array($ip,$ALLOWED_IP)) {
          $bl=false;
          foreach ($ALLOWED_IP as $val){
              if(strpos($val,'*')!==false){
                  //发现有*号替代符
                  $arr=array();
                  $arr=explode('.', $val);
                  $bl=true;
                  //用于记录循环检测中是否有匹配成功的
                  for ($i=0;$i<4;$i++){
                      if($arr[$i]!='*'){
                          //不等于* 就要进来检测，如果为*符号替代符就不检查
                          if($arr[$i]!=$check_ip_arr[$i]){
                              $bl=false;
                              break;
                              //终止检查本个ip 继续检查下一个ip
                          }
                      }
                  }
                  //end for
                  if($bl){
                      //如果是true则终止匹配
                      break;
                  }
              }
          }
          //end foreach
          if(!$bl){
              $return=array(
                'status'=>2,
                'msg'=>'该IP无权限访问',
                'data'=>$ip
              );
              echo json_encode($return); 
              exit();
          }
      }
