删除 DOI 和 urldate 之间的句点

Question

每当有 DOI 可用时，我都会在参考书目中提供它而不是 URL。在这两种情况下，我urldate还需要提供访问日期（字段）。我的问题：biblatex在 DOI 后面加一个句号，这样接下来的访问于是大写的，但 URL 后面没有句号（所以没有大写）。这看起来不太统一。

如何删除 DOI 后的句号？

梅威瑟：

\documentclass{article}

\usepackage[
    backend = biber,
    style = authortitle,
    ]{biblatex}

\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@article{a,
author = {Lily},
title = {Trees},
journaltitle = {Journal of Trees},
year = {2015},
url = {www.trees.com},
urldate = {2016-11-21},
}

@article{b,
author = {John},
title = {Flowers},
journaltitle = {Journal of Flowers},
year = {2015},
doi = {17.7-31893.23},
urldate = {2016-11-21},
}
\end{filecontents*}

\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}

给你。只需重新定义 bibmacro doi+eprint+url：

\documentclass{article}

\usepackage[
    backend = biber,
    style = authortitle,
    ]{biblatex}

\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@article{a,
author = {Lily},
title = {Trees},
journaltitle = {Journal of Trees},
year = {2015},
url = {www.trees.com},
urldate = {2016-11-21},
}

@article{b,
author = {John},
title = {Flowers},
journaltitle = {Journal of Flowers},
year = {2015},
doi = {17.7-31893.23},
urldate = {2016-11-21},
}
\end{filecontents*}

\addbibresource{\jobname.bib}

\renewbibmacro*{doi+eprint+url}{%
  \iftoggle{bbx:doi}
    {\printfield{doi}}
    {}%
  \newunit\newblock
  \iftoggle{bbx:eprint}
    {\usebibmacro{eprint}}
    {}%
  \setunit{\addspace}\newblock
  \iftoggle{bbx:url}
    {\usebibmacro{url+urldate}}
    {}}

\begin{document}
\nocite{*}
\printbibliography

\end{document}
