Please read API Based Extension to complete the development and integration of basic API service capabilities.
app.external_data_tool.query: Apply external data tools to query extension points.
This extension point takes the application variable content passed in by the end user and the input content (fixed parameters for conversational applications) as parameters to the API. Developers need to implement the query logic for the corresponding tool and return the query results as a string type.
