MetaWeblogApi 开发, 离线写博客

在学校使用的是教育网，博客园页面打开实在太慢了，但发现使用 live writer 写博客体验还不错。就想着给我们校园博客系统支持了下 MetaWeblogApi。

 

实现：

1.下载rpc： CookComputing.XmlRpcV2.dll，放在bin下面

 

2. 接口实现：IMetaWeblogApi 参考代码

3.  MetaWeblogApi.ashx处理程序

只需一行：

<%@ WebHandler Language="C#" Class="Ncuhome.Blog.MetaWeblogApi.MetaWeblogApi" %>

 

测试发布日志成功，接下来再研究怎么支持上传图片。
