借助 hyperlink 宏包优雅地在 LaTeX 文档中插入超链接
借助 hyperlink 宏包在 LaTeX 文档中插入超链接, 避免网址中特殊符号导致的美观和编译错误
偶尔需要在 LaTeX 文档中插入网址. 但是 URL 编码往往很长而且复杂, 并带有各种特殊符号, 直接放在文档里既不美观, 也经常在编译时导致错误. 借助 hyperlink 宏包的帮助可以在 LaTeX 文档中插入超链接, 避免直接放 URL 带来的种种问题.
基本配置
导入宏包并设置链接样式:
\usepackage{hyperref} % 使用宏包
% 设置链接样式
\hypersetup{
colorlinks = true,
linkcolor=blue,
filecolor=blue,
urlcolor=blue,
citecolor=cyan,
}
如果不想让超链接显示为其他颜色可以将 colorlinks 设置为 false.
链接样式有很多项目可以自定义, 参考下表:
| 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 |
针对 PDF 输出也有很多定义选项:
| 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. |
注意: hyperlink 宏包包含对很多 LaTeX 命令的重新定义, 因此在导入顺序上应当尽可能晚, 防止其中重新定义的命令又被其他宏包覆盖. 不过也有一些宏包需要在 hyperlink 之后导入:

插入链接
两种方式:
\href{https://www.google.com}{Google}
\url{https://www.google.com}
\href{mailto:[email protected]}{[email protected]}
对于邮箱地址, 可以在前面加上 mailto: , 这样点击该链接可以直接打开系统默认邮件软件发送邮件.
上面的代码排版效果如下:
在参考文献中插入超链接:
% 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}"
}
排版效果如下:
