在模板中使用{$smarty}保留变量?

{KaTeX parse error: Expected 'EOF', got '}' at position 16: smarty.get.page}̲ //类似在php脚本中访问_GET[page]

{KaTeX parse error: Expected 'EOF', got '}' at position 16: smarty.cookies.}̲ {smarty.post.}

{KaTeX parse error: Expected 'EOF', got '}' at position 16: smarty.session.}̲ {smarty.server.}
