如何在NSIS中安装后创建桌面和开始菜单的快捷方式？

!define DESKTOP_FOLDER "C:\Users\Public\Desktop"
!define SHORTCUT_NAME "MyApp.lnk"
!define SHORTCUT_TARGET "$INSTDIR\MyApp.exe"

CreateDirectory "$DESKTOP_FOLDER"
CreateShortcut "$DESKTOP_FOLDER\$SHORTCUT_NAME" "$SHORTCUT_TARGET"

!define STARTMENU_FOLDER "C:\ProgramData\Microsoft\Windows\Start Menu\Programs"
!define SHORTCUT_NAME "MyApp.lnk"
!define SHORTCUT_TARGET "$INSTDIR\MyApp.exe"

CreateDirectory "$STARTMENU_FOLDER"
CreateShortcut "$STARTMENU_FOLDER\$SHORTCUT_NAME" "$SHORTCUT_TARGET"

Section "Install"
  ; 其他安装操作
  Call CreateShortcuts
SectionEnd

Function CreateShortcuts
  ; 创建桌面快捷方式的代码
  !insertmacro DESKTOP_SHORTCUT

  ; 创建开始菜单快捷方式的代码
  !insertmacro STARTMENU_SHORTCUT
FunctionEnd
