Code Review

This pull request refactors the validation logic for references, related works, and citations by consolidating them into a single helper function, _check_id_type_id_title_items. However, this change inadvertently removes the URL format validation (using URL_RE) that was previously applied to references and related works. It is recommended to restore this validation within the helper function when the id_type is set to 'url'.

在重构 check_references 和 check_related_works 之后，它们现在统一使用 _check_id_type_id_title_items 函数进行校验。\n\n然而，原先的实现中，references 和 related_works 中的每个元素都必须是符合 URL_RE 的有效 URL。在新的实现中，如果 id_type 为 "url"，代码仅校验了 citation_id 是否为非空字符串，而没有使用 URL_RE 进行格式校验。这会导致 URL 格式校验失效（任何非空字符串都会被视为有效的 URL）。\n\n建议在 _check_id_type_id_title_items 中增加对 id_type == "url" 的校验，例如：\n\npython\n if id_type == "doi":\n if check_doi(citation_id, "paper"):\n return True\n elif id_type == "url":\n if not isinstance(citation_id, str) or not URL_RE.fullmatch(citation_id):\n return True\n elif not isinstance(citation_id, str) or citation_id == "":\n return True\n
