如何让章节名称出现在 fancyhdr 报告中？

Question

我试图让章节出现在标题中，但它总是只显示“内容”。以下是我的演示代码：

\documentclass{report}
\usepackage[demo]{graphicx}
\usepackage[final]{pdfpages}
\usepackage{hyperref}
\usepackage{fancyhdr}
\usepackage[letterpaper, margin=1in]{geometry}
\usepackage{subcaption}
\usepackage{tocloft}

\pagestyle{fancy}
\lfoot{\today}
\rfoot{\thepage}
\cfoot{}
\rhead{}
\lhead{\leftmark}
\renewcommand {\headrulewidth}{0.4pt}
\renewcommand {\footrulewidth}{0.4pt}
\renewcommand{\cftchapleader}{\cftdotfill{\cftdotsep}}

\begin{document}\thispagestyle{empty}
\setlength\unitlength{1in}

\clearpage\phantomsection
\tableofcontents

\clearpage\phantomsection
\addcontentsline{toc}{chapter}{Chapter 1}
\begin{figure}[ht]
\captionsetup[subfigure]{labelformat=empty}
\centering
\begin{subfigure}{2.125in}
  \centering
\framebox(2,2){\includegraphics[width=1.875in,height=1.875in,keepaspectratio]{infinity_80_gf_2010}}
\caption{A subfigure}
  \label{fig:sub1}
\end{subfigure}%
\begin{subfigure}{2.125in}
  \centering
\framebox(2,2){\includegraphics[width=1.875in,height=1.875in,keepaspectratio]{Plus80_2010}}
\caption{A subfigure}
  \label{fig:sub1}
\end{subfigure}%
\begin{subfigure}{2.125in}
  \centering
\framebox(2,2){\includegraphics[width=1.875in,height=1.875in,keepaspectratio]{comfort_achp_Puron}}
\caption{A subfigure}
  \label{fig:sub1}
\end{subfigure}
\end{figure}

\begin{figure}[Hb]
\captionsetup[subfigure]{labelformat=empty}
\centering
\begin{subfigure}{2.125in}
  \centering
\framebox(2,2){\includegraphics[width=1.875in,height=1.875in,keepaspectratio]{infinity_80_gf_2010}}
\caption{A subfigure}
  \label{fig:sub1}
\end{subfigure}%
\begin{subfigure}{2.125in}
  \centering
\framebox(2,2){\includegraphics[width=1.875in,height=1.875in,keepaspectratio]{Plus80_2010}}
\caption{A subfigure}
  \label{fig:sub1}
\end{subfigure}%
\begin{subfigure}{2.125in}
  \centering
\framebox(2,2){\includegraphics[width=1.875in,height=1.875in,keepaspectratio]{comfort_achp_Puron}}
\caption{A subfigure}
  \label{fig:sub1}
\end{subfigure}
\end{figure}

\end{document}

这是输出：

我希望它显示“第 1 章”
