"""#4 提现失败(withdraw_failed)推送联调脚本 —— 每次执行只发 1 条,金额 + 失败原因随机。

后台虽能驱动提现拒绝,但受「同一用户同时只能有 1 张待审单」约束,批量测试凑不齐单子;
本脚本直接调 services/notification_events.notify_withdraw_failed —— 与生产同一条下发链路:
落 notification 表(站内消息)+ 向该用户全部已注册厂商 token 直推(honor/huawei/xiaomi/oppo/vivo)。

可重复性:每次执行用全新 uuid 单号做 dedup_key,永不命中「未读去重」,想跑多少次都行。
金额默认每次随机(0.01 ~ 99.99 元)、失败原因随机 → 手机上按金额/原因就能认出这条通知;
--cents / --reason 可固定。

用法(服务端进程无需在跑,脚本自己连库 + 直调厂商接口):
  .venv\\Scripts\\python.exe scripts\\test_push_withdraw_failed.py                       # 随机金额+原因发 1 条
  .venv\\Scripts\\python.exe scripts\\test_push_withdraw_failed.py --cents 350           # 固定 3.50 元
  .venv\\Scripts\\python.exe scripts\\test_push_withdraw_failed.py --reason "自定义原因"  # 固定失败原因

结果判读(看输出日志):
  push sent   = 厂商接口受理成功,手机应弹「提现失败」通知
  push failed = 厂商拒绝(原因见日志:token 失效/凭据错误等)
  skip push   = 该厂商凭据未配置,只落站内消息
站内消息用 11111111111 登录 App → 消息中心「提现助手」可见;点击应跳提现页(extra.withdrawId)。
