最近再次测试wordpress multisite（wordpress多站点，简称WPMU）通过XML-RPC管理博客，但是始终无法通过OpenLiveWriter/WindowsLiveWriter获取到博客信息，但是通过官方“Weblog_Client”中的BlogDesk，Chrysanth WebStory却能获取到博客信息，但是BlogDesk太过于古老，且不能很好的支持中文；Chrysanth WebStory收费，免费版带有小尾巴；BlogJet收费无法测试，所以只能转战其他离线软件，但是现在离线编辑博客时代（或者是博客的时代）已经过去，基本没有新出的博客写作软件了。于是，继续研究导致这个现象的原因，通过多次测试，终于发现原因：
wordpress xmlrpc.php文件存在错误！！
但是其他其他软件为什么却能获取到博客信息呢？？
原因很简单，他们使用的XMLRPC method（API）不同，wordpress内部有多种管理博客的API：
- WordPress API
- Blogger API
- MetaWeblog API
- MovableType API等
OpenLiveWriter和WindowsLiveWriter是通过Blogger API获取博客信息的，也只有Blogger API存在错误，所以其他软件可以，但是OpenLiveWriter和WindowsLiveWriter不可以！！
Blogger API比WordPress API的getUsersBlogs方法多一个参数，在WPMU多站点版(multisite)获取博客信息时，如果采用Blogger API会直接调用WordPress API，但是调用时并没有去除多的那个参数，所以导致一直验证失败！！

if ( ! $this->minimum_args( $args, 2 ) ) {

// If this isn't on WPMU then just use blogger_getUsersBlogs().

array_unshift( $args, 1 );

$this->escape( $args );
$username = $args[0];
$password = $args[1];
