我有以下代码：

\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage[citestyle=bwl-fu, maxcitenames=3, maxbibnames=20, firstinits=true]{biblatex}
\addbibresource{literature.bib}
\renewcommand{\mkbibnamefamily}[1]{\textsc{#1}} % Authors in small caps in citation and bibliography
\DeclareNameAlias{default}{last-first} % family name, given name
\renewcommand*{\multinamedelim}{\addsemicolon\space} % semicolon between two authors
\DeclareFieldFormat{labelnumberwidth}{Test} % print nothing in the label
\DeclareCiteCommand{\cite} % hyperlink authoryear to bibliography
{\usebibmacro{prenote}}
{\usebibmacro{citeindex}%
\printtext[bibhyperref]{\usebibmacro{cite}}}

\end{filecontents}
\begin{document}
\chapter{Test-Kapitel}
\cite{Mueller.2018} haben eine Meinung. Aber \cite{Junker.2008} sehen das anders.
\printbibliography[title=Literaturverzeichnis]
\end{document}
但是参考书目中不需要“测试”，我需要作者（年份）作为参考。我想要的是类似这样的内容：
谢谢！

bwl-fu只是标准authoryear样式的一个相当薄的包装，所以我会尝试重新创建它的功能biblatex-ext，您可以在其中使用该选项introcite获取参考书目中的引用标签。
您可以在下方找到有关introcite以下内容的更多信息和大多数其他用途biblatex-ext文档。
