Request help @bzp2010 @tzssangglass @spacewander

please help me to make sure when we configure service discovery, can we configure these fields? Since I have not fond the related examples, and some of the fields such as timeouts configured in the yaml file

• https://apisix.apache.org/docs/apisix/discovery/nacos/
• https://github.com/apache/apisix/blob/master/t/discovery/nacos.t

[bzp2010]

Hi, @liuxiran. According to the schema, there is no difference except that the fields in the box are one of two.

[liuxiran]

please pay attention to

It should be noted that, when discovery_type choose nacos, discovery_args can be configured, see: https://apisix.apache.org/docs/apisix/2.7/discovery/nacos#discovery_args for details.

when choose nacos as service_type, discovery_args can be configured
