需求：

1. 功能模块：

   有、发布文章、上传文件、记录学习（包含：笔记、思维导图



下面是一份图书馆系统的用户模块的API请求结构的示例：

用户注册：
请求地址：/register
请求方法：POST
请求参数：username、password、email、phone_number
返回结果：{'code': 0, 'msg': 'Success'} 或 {'code': 1, 'msg': 'Username has been registered'}
用户登录：
请求地址：/login
请求方法：POST
请求参数：username、password
返回结果：{'code': 0, 'msg': 'Success', 'user_id': 123} 或 {'code': 1, 'msg': 'Username or password is incorrect'}
获取用户信息：
请求地址：/user/{user_id}
请求方法：GET
请求参数：无
返回结果：{'code': 0, 'msg': 'Success', 'data': {'username': 'john', 'email': 'john@example.com', 'phone_number': '1234567890'}}
以上是一个简单的图书馆系统用户模块的API请求结构的示例，具体的结构可以根据项目的需求进行调整。

如果您想删除用户的API请求结构，可以这样设计：

DELETE /api/v1/users/{user_id}: 删除指定ID的用户
请求示例：

DELETE /api/v1/users/12345

HTTP/1.1 200 OK
Content-Type: application/json;charset=UTF-8

{
  "message": "User deleted successfully"
}

响应示例：

如果删除成功，返回 HTTP 状态码 200 和提示信息 "User deleted successfully"。
请注意，这仅是一个示例。您可以根据您的需求和数据模型来设计具体的API接口。
