============問題描述============
做個天氣預報的小測試用網上找的連結怎麼不行，有做過的指導下。感激不盡！！
求用法或可用連結！！！！！！！！！！
http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx
和
http://www.webxml.com.cn/webservices/weatherwebservice.asmx
都是不行的！跟著網上例子做的。

都是網上找的，大拿們速來救火！！
============解決方案1============
這兩個介面都已經失效了，沒法訪問，你找個能用的，用瀏覽器就可以測試
============解決方案2============
樓主現在解決了嗎？求解
============解決方案3============
網路許可權開了嗎
============解決方案4============
看看有沒有返回資料就清楚了
============解決方案5============
Unable to resolve host "webservice.webxml.com.cn": No address associated with hostname
這個意思是網域名稱解析不正常，確信網路OK？
============解決方案6============
這個網站現在應用廣泛嗎？ 看了一下他們的介面文檔，真心覺得不怎麼樣啊，沒有一點做開放平台的水準。。。。，
android怎麼訪問天氣webservice，用網上找的連結都不行啊
