不显示“（访问于)”在参考文献中

Question

我正在使用 biblatex，并且我希望不显示参考书目中的某些字段。我已成功为“issn”、“url”和“doi”字段实现了此操作，但对“urldate”字段不起作用，并且参考文献上会出现“(visited on )”。下面是一段最简洁的代码。我该如何隐藏“(visited on )”？

\documentclass[conference]{IEEEtran}
\usepackage[style=ieee,backend=biber]{biblatex}
\bibliography{rtacft_biblatex}
\AtEveryBibitem{\clearfield{issn}}    % clears ISSN
\AtEveryBibitem{\clearfield{url}}    % clears url
\AtEveryBibitem{\clearfield{doi}}    % clears DOI
\begin{document}
Test \cite{xiang_novel_2010}.
\printbibliography
\end{document}

Answer 1

您可以告诉biblatex包选项不要显示 URL 等等。
