\documentclass[a4paper,10pt]{article}

\usepackage{natbib}
\usepackage{apalike}

\usepackage{hyperref}
\hypersetup{
    hidelinks=false,             
    colorlinks=true,
    citecolor=blue
}

\begin{document}
    
    This is an example of ... \citep{author1}.
    
    \bibliographystyle{apalike}
    \bibliography{Bibliography}
\end{document} 

参考书目.bib

@book{author1,
  title={Book Title},
  author={Author},
  year={2014},
  publisher={Publisher}
}

Answer 1

花费了一些时间来找到正确的\NAT@hyper@补丁调用。

\begin{filecontents*}{\jobname.bib}
@book{author1,
  title={Book Title},
  author={Author},
  year={2014},
  publisher={Publisher}
}
\end{filecontents*}
