都是网上找的，大拿们速来救火！！

====================解决方案1====================
这两个接口都已经失效了，没法访问，你找个能用的，用浏览器就可以测试
====================解决方案2====================
楼主现在解决了吗？求解
====================解决方案3====================
网络权限开了吗
====================解决方案4====================
看看有没有返回数据就清楚了
====================解决方案5====================
Unable to resolve host "webservice.webxml.com.cn": No address associated with hostname

这个意思是域名解析不正常，确信网络OK？
====================解决方案6====================
这个网站现在应用广泛吗？看了一下他们的接口文档，真心觉得不怎么样啊，没有一点做开放平台的水准。。。。，
