Is there an upgrade guide for configs?

[grantholle]

I'm trying to update from v2 to v3 and am confused on some of the configuration key changes. Specifically, what v2's ali_public_key and private_key map to in v3 for alipay.

Because of alipay's recommendation about using certificate, we have changed some configuration.

private_key -> app_secret_cert and app_public_cert_path

ali_public_key -> alipay_public_cert_path and alipay_root_cert_path

You can check the pay doc via https://pay.yansongda.cn/docs/v3/quick-start/init.html
