在LaTeX参考文献中插入超链接

(Updated: )
LaTeX技巧

借助hyperlink宏包可以较好地解决参考文献中插入链接的问题。

不借助宏包的帮助在LaTeX文档中插入链接是一件很麻烦的事情，因为网址的结构往往很复杂且带有各种符号，容易编译的时候容易出错。特别是遇到下划线、百分号这些符号。此外，在文档中插入一大堆乱七八糟的符号也不是很美观。使用hyperlink宏包可以较好地解决这个问题。

基本配置

在文档中添加如下代码：

1
2
3
4
5
6
7
8
9
10
\usepackage{hyperref} % 使用宏包

% 设置链接样式
\hypersetup{
    colorlinks = true,
    linkcolor=blue,
    filecolor=blue,      
    urlcolor=blue,
    citecolor=cyan,
}
  • 如果不想让链接变成其他颜色可以将colorlinks设置为false
  • 链接样式还有很多可以自定义的项目，详情如下表1：

Linking style options

Option Default value Description
hyperindex true Makes the page numbers of index entries into hyperlinks
linktocpage false Makes the page numbers instead of the text to be link in the Table of contents.
breaklinks false Allows links to be broken into multiple lines.
colorlinks false Colours the text for links and anchors, these colours will appear in the printed version
linkcolor red Colour for normal internal links
anchorcolor black Colour for anchor (target) text
citecolor green Colour for bibliographical citations
filecolor cyan Colour for links that open local files
urlcolor magenta Colour for linked URLs
frenchlinks false Use small caps instead of colours for links

PDF-specific options

Option Default value Description
bookmarks true Acrobat bookmarks are written, similar to the table of contents.
bookmarksopen false Bookmarks are shown with all sub-trees expanded.
citebordercolor 0 1 0 Colour of the box around citations in RGB format.
filebordercolor 0 .5 .5 Colour of the box around links to files in RGB format.
linkbordercolor 1 0 0 Colour of the box around normal links in RGB format.
menubordercolor 1 0 0 Colour of the box around menu links in RGB format.
urlbordercolor 0 1 1 Colour of the box around links to URLs in RGB format.
pdfpagemode empty Determines how the file is opened. Possibilities are UseThumbs (Thumbnails), UseOutlines (Bookmarks) and FullScreen.
pdftitle Sets the document title.
pdfauthor Sets the document Author.
pdfstartpage 1 Determines on which page the PDF file is opened.
  • hyperlink宏包包含对很多LaTeX命令的重新定义，因此应当尽可能晚地加载，否则可能导致一些排版异常。当然也有一些宏包（如cleveref等）需要在hyperlink之后加载2。

插入链接

有两种插入链接的方式：

1
2
3
4
5
\href{https://www.google.com}{Google}

\url{https://www.google.com}

\href{mailto:[email protected]}{[email protected]}

对于邮箱地址，可以在链接前面加上mailto:，这样点击链接就会自动唤起系统默认邮件应用。

点击链接即可跳转。

在参考文献中插入链接

如果使用BibTeX生成参考文献列表，可以在.bib文件中对应项的合适位置加上上面超链接：

1
2
3

% file: main.tex
Introduction to LaTeX\cite{enwiki:1023081178}.

% file: ref.bib
@misc{ enwiki:1023081178,
    author = "{Wikipedia contributors}",
    title = "LaTeX --- {Wikipedia}{,} The Free Encyclopedia",
    year = "2021",
    url = "https://en.wikipedia.org/w/index.php?title=LaTeX&oldid=1023081178",
    note = "[Online; accessed 10-July-2021]. \url{https://en.wikipedia.org/w/index.php?title=LaTeX&oldid=1023081178}"
}

上面的代码排版效果如下：
