前不久看见一篇文章:在ASP.NET中使用Response.Filter 过滤网站敏感字符的解决方案。于是我借题发挥用Response.Filter 为MVC2.0 进行多国语言本地化。如果存在不足的地方,希望您指出。
本文主要给出具体思路,希望能给读者带来一定的启发:日常开发中不是所有的方案要中规中矩用常用方法解决问题。比如本文的本地化就不用resource文件来处理。
具体步骤:
一、建立自定义的LocalizationHandler类
LocalizationHandler 继承System.IO.Stream类 ,LocalizationHandler实例化后赋值给Response.Filter。这里主要通过Response.Filter来本地化MVC2.0程序。具体的Response.Filter 用法请参看MSDN.代码如下:
public class LocalizationHandler : Stream { private Stream responseStream; public LocalizationHandler(Stream inputStream) { responseStream = inputStream; } public override bool CanRead { get { return true; } } public override bool CanSeek { get { return true; } } public override bool CanWrite { get { return true; } } public override void Flush() { responseStream.Flush(); } public override long Length { get { return 0; } } long postion; public override long Position { get { return postion; } set { postion = value; } } public override int Read(byte[] buffer, int offset, int count) { return responseStream.Read(buffer, offset, count); } public override long Seek(long offset, SeekOrigin origin) { return responseStream.Seek(offset, origin); } public override void SetLength(long value) { responseStream.SetLength(value); } public override void Write(byte[] buffer, int offset, int count) { string sBuffer = System.Text.UTF8Encoding.UTF8.GetString(buffer, offset, count); string pattern = @"(|)=(.*?)(|)";//正则替换类似页面格式为这样的字符串如:=OtherContent sBuffer = Regex.Replace(sBuffer, pattern, delegate(Match c) { return ReadLocalizationResource().FirstOrDefault(d = d.Key == c.Groups[2].Value).Value; }); ReadLocalizationResource(); byte[] data = System.Text.UTF8Encoding.UTF8.GetBytes(sBuffer); responseStream.Write(data, 0, data.Length); } ObjectCache cache = MemoryCache.Default; private Dictionarystring, string ReadLocalizationResource() { string _XMLPath = ""; Dictionarystring, string cacheData = null; if (cacheData != null) { return cacheData; } Dictionarystring, string cachedData = new Dictionarystring, string(); string serverPath = System.Web.HttpContext.Current.Server.MapPath("~"); _XMLPath = Path.Combine(serverPath, "LocalizationResource.xml"); //建立缓存(使用.NET4.0最新缓存机制:System.Runtime.Caching;) if (cache["myCache"] == null) { CacheItemPolicy policy = new CacheItemPolicy(); policy.SlidingExpiration = TimeSpan.FromMinutes(60); policy.ChangeMonitors.Add(new HostFileChangeMonitor(new Liststring { _XMLPath })); var items = XElement.Load(_XMLPath).Elements("Module").Elements("item"); foreach (var item in items) { string key = item.Attribute("name").Value; string value = item.Value; cachedData.Add(key, value); } cache.Set("myCache", cachedData, policy); return cachedData; } return (Dictionarystring, string)cache["myCache"]; } }
