参考课程中的文档资料简单写了一个，感觉不太对的样子和课程的结构对不上：

{
    "description": "提供用户注册和初始配置设置的API。",
    "server": "https://dict.youdao.com",
    "paths": {
        "/register": {
            "post": {
                "description": "允许用户注册新账号并配置初始设置。",
                "operationId": "registerUser",
                "parameters": [{
                    "name": "q",
                    "in": "request_body",
                    "description": "要检索查询的单词，例如love/computer",
                    "required": [
                        "username",
                        "email",
                        "password"
                    ],
                    "type": "object"
                }],
                "properties": {
                    "username": {
                        "type": "string",
                        "description": "用户的唯一用户名",
                        "example": "johndoe"
                    },
                    "email": {

                        "description": "用户的电子邮件地址",
                        "format": "email",

                    },
                    "password": {
                        "type": "string",
                        "description": "用户的密码，需至少8个字符",
                        "format": "password",
                        "example": "strongpassword123"
                    }
                }
            }
        }
    }
