弯曲箭头内的弯曲文字

Question

我正在尝试让放置在弯曲箭头内的文本随箭头弯曲。我有以下代码可以生成给定的图片，但我不知道如何让文本随箭头弯曲。我找到了一个解决方案建议这里，但我无法将其调整到适合我的情况。特别是，我真的很想修改 vecArrow 的定义以执行我想要的操作（最好使用文本作为参数）。任何帮助都将不胜感激。

\documentclass[table,xcolor=pdftex,dvipsnames]{beamer}

\usepackage{tikz}

\usetikzlibrary{arrows,shapes,snakes,positioning,decorations.text,decorations.pathmorphing,decorations.markings}

\begin{document}

\begin{frame}
   \frametitle{Curved Arrow}
 \tikzset{
vecArrow/.style={
  line width=3ex,
  decoration={markings,mark=at position
   1 with {\arrow[scale=2, blue!20!white]{triangle 60}}},
    blue!20!white,
  shorten >= 32pt,
  line width=4pt,
  preaction = {decorate},
  postaction = {draw=blue!20!white,line width=3ex, shorten >= 30pt}
  }
}

\begin{tikzpicture}
\node[rectangle,draw,minimum width=2in, minimum height=1in] (box1) {};
\node[rectangle,draw,minimum width=2in, minimum height=1.5in,below right=of box1] (box2) {};
\draw[vecArrow]  (box1.east) to[in=135,out=45] node[black,rotate=-47,anchor=west,xshift=-6mm]{\scriptsize Subgraph Match} (box2.north);

\end{tikzpicture}

\end{frame}
\end{document}

以下是一种方法：

\documentclass[table,xcolor=pdftex,dvipsnames]{beamer}

\usepackage{tikz}

\usetikzlibrary{arrows.meta,bending,positioning,decorations.text}

\begin{document}
  \tikzset{
    vecArrow/.style={
      draw, line width=3ex, blue!20!white, -{Triangle[bend, angle=60:1pt 2]}, shorten >=6pt, postaction=decorate, decoration={text along path, text color=black, text align=center, text={|\scriptsize|#1 ||}}
    }
  }
  \begin{frame}
    \frametitle{Curved Arrow}
    \begin{tikzpicture}
      \node[rectangle,draw,minimum width=2in, minimum height=1in] (box1) {};
      \node[rectangle,draw,minimum width=2in, minimum height=1.5in,below right=of box1] (box2) {};
      \path [vecArrow=Subgraph Match] (box1.east) to[in=135,out=45] (box2.north);
    \end{tikzpicture}
  \end{frame}
\end{document}
