本文介绍了一种通过调用WebService来获取特定地区的天气信息的方法。文中详细展示了如何使用Java编程语言来调用WebService接口，获取省份列表、城市列表及具体城市的天气详情。

// 定义Web Service的命名空间

static final String SERVICE_NS = "http://WebXml.com.cn/";
// 定义Web Service提供服务的URL
static final String SERVICE_URL = "http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx";
/**
* 获取省的列表
* @return
*/
public static List<String> getProvinceList() {
// 调用的方法
final String methodName = "getRegionProvince";
// 创建HttpTransportSE传输对象
final HttpTransportSE ht = new HttpTransportSE(SERVICE_URL);
ht.debug = true;
// 使用SOAP1.1协议创建Envelop对象
final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
// 实例化SoapObject对象
SoapObject soapObject = new SoapObject(SERVICE_NS, methodName);
envelope.bodyOut = soapObject;
// 设置与.Net提供的Web Service保持较好的兼容性
envelope.dotNet = true;
FutureTask<List<String>> task = new FutureTask<List<String>>(
new Callable<List<String>>(){
@Override
public List<String> call()throws Exception{
// 调用Web Service
ht.call(SERVICE_NS + methodName, envelope);
if (envelope.getResponse() != null){
// 获取服务器响应返回的SOAP消息
SoapObject result = (SoapObject) envelope.bodyIn;
SoapObject detail = (SoapObject) result.getProperty(
methodName + "Result");
// 解析服务器响应的SOAP消息。
return parseProvinceOrCity(detail);
}
return null;
}
});
new Thread(task).start();
try{
return task.get();
}
catch (Exception e){
e.printStackTrace();
}
return null;
}
