小程序V3版本支付，openid问题Small program V3 version payment, openid problem

According to the official V3 document of wechat, the wechat payment unified order (direct connection mode) does not need openid https://pay.weixin.qq.com/wiki/doc/apiv3/apis/chapter3_ 5_ 1. Shtml, but the official example needs openid https://pay.weixin.qq.com/wiki/doc/apiv3/open/pay/chapter2_ 8_ 2. Shtml so under the direct connection mode and service provider mode, does the V3 version need openid for unified order?
