在开发Tiray Blog Ping的过程中,总是发现有道( http://www.youdao.com/ )的博客Ping Service( http://blog.yodao.com/ping/RPC2 )返回错误，开始认为是自己的程序有错，后来用Windows Live Writer 测试后，发现结果也是一样！也许有道的程序员应该检查一下Ping Service接口了！有道的Ping Service说明地址：http://www.yodao.com/help/blogsearch/description/006/
以下数据都是用Fiddler截获的！
下面是Windows Live Writer向有道发送的Ping命令数据包:
POST /ping/RPC2 HTTP/1.0

下面是有道返回的数据包(居然是“No such handler: weblogUpdates.ping”):

下面是有道返回的数据包(表明调用方法的参数不正确):

为了检验是否是因为字符编码引起的问题，移除了所有中文字符，再次用Tiray Blog Ping 发送Ping命令,结果也是一样！
下面是向有道发送的Ping命令：
