I used file upload when creating the knowledge base, and the file name is api.txt
#Company Technical Documents

1. system architecture

Our system adopts a microservice architecture, where each service module runs independently and interacts with each other through APIs.

2. Database Design

The database uses MySQL to store all user data, and the table structure is as follows:
-User Table: id, name, email
-Product List: id, name, price

3. API Design

All APIs adopt RESTful style, and the following are common interfaces:
-GET/users: Get all users
-POST/products: Add new products
return：

I don't know how to solve this problem, can you help me take a look.Thank you!
