最近公司项目使用WebService ，这里简单做个总结。 其实具体使用细节有些情况下需要改，还需要看实际情况，需要与服务器联调，具体沟通。比如公司连接，非要把envelope.dotNet = true; 设置为false,  某个<soap12:operation soapAction="http://WebXml.com.cn/getCountryCityByIp" style="document"/> soapAction为空的，就不能使用soapAction来访问，有的传递参数是json字符串......

公共接口很多：http://www.webxml.com.cn/zh_cn/index.aspx

这里使用获取天气接口：

直接上代码吧。比较简单，由于时间关系，没有详细做。但是大体上如何使用应该还是可以看的出来。但，还是研究比较深要好点。
