Get the configuration of the specified child node under the specified instantiated rule chain. Used for rule chain visual configuration echo.

func (e *RuleEngine) NodeDSL(subChainId types.RuleNodeId, childNodeId types.RuleNodeId) []byte

• subChainId: Sub-rule chain ID, if querying the root rule chain node, fill in: types.EmptyRuleNodeId
• childNodeId: Child node ID, for example: types.RuleNodeId{Id: nodeId}
• Return: Node instantiation configuration (JSON structure)

Example:

// Get the rule chain instance that has been created by the rule chain ID
ruleEngine,_:rulego.Get(chainId)
// Get the rule chain child node configuration
def = ruleEngine.NodeDSL(types.EmptyRuleNodeId, types.RuleNodeId{Id: nodeId, Type: types.NODE})
fmt.Println(string(def))

The rule chain node configuration supports dynamic updates, dynamic replacement of business logic and component configuration, refer to the documentation. Used for rule chain modification.
