给“章”装饰一个带框的小目录

代码实现如下：

\documentclass{book}
\usepackage[explicit]{titlesec}
\usepackage{lmodern}
\usepackage{titletoc}
\usepackage[many]{tcolorbox}

\newcommand\chapnumfont{\fontsize{50}{60}\selectfont}
\newcommand\chapnamefont{\huge}
\newcommand\chaptitlefont{\LARGE}

\makeatletter
\titleformat{\chapter}
  {\startcontents\bfseries\sffamily}
  {}
  {0pt}
  {}
  [{%
    \filleft{\chapnamefont\@chapapp}\\
    \begin{minipage}[b]{.75\textwidth}
    \begin{tcolorbox}[
      width=\linewidth,
      enhanced,
      top=10pt,
      nobeforeafter,
      outer arc=0pt,
      arc=0pt,
      boxrule=0.6pt,
      colback=white,
      overlay={
        \node[anchor=west,fill=white,inner xsep=6pt]
          at ([xshift=10pt]frame.north west)
          {Sommaire};
      }
    ]
      \printcontents{}{1}{}
    \end{tcolorbox}%
    \end{minipage}%
    \begin{minipage}[b]{.25\textwidth}
      \filleft
      \chapnumfont\thechapter
    \end{minipage}\\[10pt]
    {\chaptitlefont#1}
    }%
  ]
\titleformat{name=\chapter,numberless}
  {\startcontents\bfseries\sffamily\filleft}
  {}
  {0pt}
  {\chaptitlefont#1}
\makeatother

\begin{document}

\tableofcontents

\chapter{Test chapter one}
\section{Test section one one}
\section{Test section one two}
\section{Test section one three}


\chapter{Test chapter two}
\section{Test section two one}
\section{Test section two two}
\section{Test section two three}
\section{Test section two four}
\section{Test section two five}

\end{document}
