Golang中的HTML模板

使用template.HTML将正文标记为安全HTML。

以下函数将正文转换为HTML。

// Move to package-level variable so that it's compile once.var linkPat = regexp.MustCompile(`[.+]`)func toHTML(s string) template.HTML {  // Escape everything in the string first to ensure that  // special characters ('<' for example) are displayed as  // characters and not treated as markup.  s = template.HTMLEscapeString(s)  // Insert the links.  s = linkPat.ReplaceAllStringFunc(s, func(m string) string {    s = s[1 : len(s)-1]    return "<a href='/view/" + m + "'>" + m + "</a>"  })  return template.HTML(s)}

使用以下方式渲染页面：

renderTemplate(w, "edit", map[string]interface{}{   "Title": p.Body,   "Body": toHTML(p.Body),})
