## [2.7.8] - 2026-10-07

### Summary

本次更新修复禁漫 API 响应携带 UTF-8 BOM 导致 JSON 解析与校验失败的问题(#585),并兼容空下载场景下的 GitHub Actions 工作流。

### Fixed

- **API 响应 UTF-8 BOM 兼容与校验统一**:在 `JmcomicText.try_parse_json_object` 中增加对 UTF-8 BOM 字符(`\ufeff`)的过滤剥离,并在同步/异步客户端中统一使用该方法进行 API 响应合法性校验,彻底解决因 BOM 导致客户端误判为非 JSON 响应并反复重试耗尽的问题([#585](https://github.com/hect0x7/JMComic-Crawler-Python/issues/585))。
- **下载 Actions 工作流空目录保护**:在 `download.yml` 与 `download_dispatch.yml` 中增加对 `$JM_DOWNLOAD_DIR` 是否存在及是否非空的判断;在无本子下载时跳过压缩和构件上传,避免目录不存在导致工作流异常中断。

Validate the complete response as a JSON object.

For responses below HTTP 500, try_parse_json_object can match a valid object embedded in an HTML error page, such as a script containing {"error":"blocked"}. Both validators then treat the HTML body as valid and skip the exception that triggers retry. The previous first-character check rejected this body. Parse the full BOM-normalized text and require a dict in both validators.

Review comment at @src/jmcomic/jm_client_impl.py at line 1267:
Update the response validation at the visible JmcomicText.try_parse_json_object
call to parse the complete BOM-normalized response text as JSON and require the
result to be a dict, so embedded objects in HTML are rejected and trigger the
existing retry path. Apply the same validation in the async response validator.
