 *
 * [task_local]
 * # 财新每日任务
 * 5 0 * * * https://github.com/ddgksf2013/Scripts/raw/master/caixin_daily.js, tag=财新每日任务, enabled=true

hostname = gateway.caixin.com
 *
 *
 *************************
 【BoxJS 配置】:
 *************************
 *
 * 配置文件：
 * https://raw.githubusercontent.com/ddgksf2013/BoxJS/refs/heads/main/caixin.boxjs.json
 *
 * AI 相关参数通过 BoxJS 配置：
 * - API URL
 * - API Key
 * - AI 模型
 * - API 接口模式
 *
 * API Key 不写入脚本，也不会输出到日志。
 *
 *
 *************************
 【授权获取方法】:
 *************************
 *
 * 1. 添加对应代理工具的脚本配置
 *
 * 2. 开启 Rewrite / HTTP Request
 *
 * 3. 开启 MITM，并正确安装、信任证书
 *
 * 4. 登录财新 App
 *
 * 5. 依次进行以下操作：
 *
 *    - 打开积分页面
 *    - 打开知识问答页面
 *    - 打开任意文章
 *    - 点击一次分享
 *
 * 6. 收到“财新授权抓取”成功通知后即表示授权保存成功
 *
 * 授权获取完成后建议关闭 Rewrite / HTTP Request，
 * 日常只保留“财新每日任务”定时任务即可。
 *
 *
 *************************
 【答题逻辑】:
 *************************
 *
 * 每日知识问答采用以下逻辑：
 *
 * 1. 首先检查账号当天是否已经答题
 *
 * 2. 如果存在已答账号：
 *    - 优先从答题详情接口读取官方答案
 *    - 后续账号直接复用该官方答案
 *    - 不再调用 AI
 *
 * 3. 如果所有账号都尚未答题：
 *    - 首个需要答题的账号调用 BoxJS 配置的 AI
 *    - AI 根据当天题目给出答案
 *    - 脚本自动提交答案
 *
 * 4. 首个账号提交答案后：
 *    - 从财新接口响应中提取官方正确答案
 *    - 官方答案仅保存在当前脚本运行内存中
 *
 * 5. 后续账号：
 *    - 直接复用本次运行取得的官方答案
 *    - 不重复调用 AI
 *
 * 6. 不读取、不保存任何本地题库
 *
 * 7. 不持久化保存：
 *    - 题目
 *    - AI 答案
 *    - 官方答案
 *    - 正确答案
 *
 *
 *************************
 【分享任务逻辑】:
 *************************
 *
 * 1. 自动读取财新当天任务配置及任务进度
 *
 * 2. 判断当天分享任务已经完成的次数
 *
 * 3. 根据剩余任务次数自动补足分享
 *
 * 4. 默认最多执行 5 次分享
 *
 * 5. 已完成分享任务时自动跳过
 *
 *
 *************************
 【积分核验】:
 *************************
 *
 * 每个任务执行时均会进行积分核验：
 *
 * 1. 执行任务前读取当前积分
 *
 * 2. 执行：
 *    - 签到
 *    - 知识问答
 *    - 分享任务
 *
 * 3. 执行完成后重新读取积分
 *
 * 4. 对比任务前后的积分变化
 *
 * 5. 避免出现：
 *    “接口返回成功，但实际账户没有增加积分”
 *    这种情况下的错误成功提示
 *
 *
 *************************
 【多账号说明】:
 *************************
 *
 * 支持多个财新账号。
 *
 * 当抓取到新的账号授权时自动保存；
 * 已存在的账号再次抓取时自动更新授权信息。
 *
 * 多账号运行时依次执行：
 *
 * - 查询积分
 * - 每日签到
 * - 知识问答
 * - 分享任务
 * - 最终积分核验
 *
 * 同一天题目一致时，
 * 后续账号优先复用本次运行取得的官方答案，
 * 减少不必要的 AI 请求。
 *
 *
 *************************
 【定时任务】:
 *************************
 *
 * 默认每天：
 *
 * 00:05
 *
 * 自动执行财新每日任务。
 *
 * Cron：
 *
 * 5 0 * * *
 *
 *
 *************************
 【注意事项】:
 *************************
 *
 * - 本脚本仅供学习与交流使用
 *
 * - API URL、API Key、模型名称及接口模式均通过 BoxJS 配置
 *
 * - 请勿将自己的 API Key 直接写入脚本或公开仓库
 *
 * - 授权信息属于敏感信息，请勿复制给他人或上传到公开位置
 *
 * - 财新接口规则发生变化后，脚本可能需要同步更新
 *
 * - 授权获取完成后建议关闭 Rewrite / HTTP Request，
 *   减少不必要的请求拦截
