ASP.NET MVC生成静态页面的方法

本文主要讲述了在asp.NET mvc中，页面静态化的方法。对于网站来说，生成纯html静态页面除了有利于seo外，还可以减轻网站的负载能力和提高网站性能。

1.先付上封装好生成静态页的原代码：

public class Common
{
  #region 获取模板页的Html代码
  /// <summary>
  /// 获取页面的Html代码
  /// </summary>
  /// <param name="url">模板页面路径</param>
  /// <param name="encoding">页面编码</param>
  /// <returns></returns>
  public static string GetHtml(string url, System.Text.Encoding encoding)
  {
    byte[] buf = new WebClient().DownloadData(url);
    if (encoding != null)
    {
      return encoding.GetString(buf);
    }
    string html = System.Text.Encoding.UTF8.GetString(buf);
    encoding = GetEncoding(html);
    if (encoding == null || encoding == System.Text.Encoding.UTF8)
    {
      return html;
    }
    return encoding.GetString(buf);
  }

  /// <summary>
  /// 获取页面的编码
  /// </summary>
  /// <param name="html">Html源码</param>
  /// <returns></returns>
  public static System.Text.Encoding GetEncoding(string html)
  {
    string pattern = @"(?i)bcharset=(?<charset>[-a-zA-Z_0-9]+)";
    string charset = Regex.Match(html, pattern).Groups["charset"].Value;
    try
    {
      return System.Text.Encoding.GetEncoding(charset);
    }
    catch (ArgumentException)
    {
      return null;
    }
  }
  #endregion

  #region 用于生成Html静态页
  /// <summary>
  /// 创建静态文件
  /// </summary>
  /// <param name="result">Html代码</param>
  /// <param name="createpath">生成路径</param>
  /// <returns></returns>
  public static bool CreateFileHtmlByTemp(string result, string createpath)
  {
    if (!string.IsNullOrEmpty(result))
    {
      if (string.IsNullOrEmpty(createpath))
      {
        createpath = "/default.html";
      }
      string filepath = createpath.Substring(createpath.LastIndexOf(@""));
      createpath = createpath.Substring(0, createpath.LastIndexOf(@""));
      if (!Directory.Exists(createpath))
      {
        Directory.CreateDirectory(createpath);
      }
      createpath = createpath + filepath;

      try
      {
        FileStream fs2 = new FileStream(createpath, FileMode.Create);
        StreamWriter sw = new StreamWriter(fs2, new System.Text.UTF8Encoding(false));//去除UTF-8 BOM
        sw.Write(result);
        sw.Close();
        fs2.Close();
        fs2.Dispose();
        return true;
      }
      catch (Exception ex)
      {
        throw ex;
      }
    }
    return false;
  }
  #endregion

  #region 调用静态模板，并且传递数据模型实体类 创建Html静态页
  /// <summary>
  /// 解析模板生成静态页
  /// </summary>
  /// <param name="temppath">模板地址</param>
  /// <param name="path">静态页地址</param>
  /// <param name="t">数据模型</param>
  /// <returns></returns>
  public static bool CreateStaticPage<T>(string temppath, string path, T t)
  {
    try
    {
      //获取模板Html
      string TemplateContent = GetHtml(temppath, System.Text.Encoding.UTF8);

      //初始化结果
      string result = string.Empty;

      //解析模板生成静态页Html代码
      result = Razor.Parse(TemplateContent, t);

      //创建静态文件
      return CreateFileHtmlByTemp(result, path);
    }
    catch (Exception e)
    {
      throw e;
    }
  }
  #endregion
}
