资源地址：http://www.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl"
这里提供两种调用WebService服务的方法，过程中axis2的依赖包需自行添加。
通过axis2插件生成本地代理文件
axis2的安装使用自行搜索，这里提供一个转载的别人的链接。之后在Eclipse(idea也可)新建一个工程，将资源地址的wsdl文件下载copy到工程里面，利用axis2生成本地代理，如下图
接着写一个客户端类WeatherTest用来调用服务
public class WeatherTest {
public static void main(String[] args) throws ServiceException, RemoteException {
WeatherWSLocator locator = new WeatherWSLocator();
WeatherWSSoapStub service = (WeatherWSSoapStub) locator.getPort(WeatherWSSoapStub.class);
invokeGetSupportProvince(service);
invokeGetSupportCityString(service);
invokeGetWeather(service);
}
// 调用获取支持的省份、州接口
private static void invokeGetSupportProvince(WeatherWSSoapStub service) throws RemoteException {
// TODO Auto-generated method stub
String[] provices = service.getRegionProvince();
System.out.println("总共" + provices.length + "个区域省");
int count = 0;
for (String str : provices) {
if (0 != count && count % 5 == 0) {
System.out.println();
}
String regEx = "(.*?),(\\d+)";
Pattern pattern = Pattern.compile(regEx);
Matcher matcher = pattern.matcher(str);
if (matcher.find()) {
System.out.print(matcher.group(1) + "\t");
count++;
}
}
System.out.println("\n"+"----------------------");
}
// 调用获取支持查询某个省份内的城市接口
public static void invokeGetSupportCityString(WeatherWSSoapStub service) throws RemoteException {
String provinceName;
System.out.print("输入要查询的区域或省：");
Scanner input = new Scanner(System.in);
provinceName = input.next();
String[] cities = service.getSupportCityString(provinceName);
System.out.println("总共" + cities.length + "个市");
for (int i = 0; i < cities.length; i++) {
if (0 != i && i % 5 == 0) {
System.out.println();
}
String regEx = "(.*?),(\\d+)";
Pattern pattern = Pattern.compile(regEx);
Matcher matcher = pattern.matcher(cities[i]);
if (matcher.find()) {
System.out.print(matcher.group(1) + "\t");
}
}
System.out.println("\n"+"----------------------");
}
// 调用查询某个城市天气的接口
public static void invokeGetWeather(WeatherWSSoapStub service) throws RemoteException {
String cityName;
System.out.print("输入要查询的城市：");
Scanner input = new Scanner(System.in);
cityName = input.next();
String[] weatherInfo = service.getWeather(cityName, null);
for (String str : weatherInfo) {
System.out.println(str);
}
}
}
运行该类即可得到天气结果，需要注意的是这种方式返回的是字符串数组
以soap消息的方式发送http请求
soap的语法可去菜鸟教程或W3school查看。该方式返回的也是soap消息，因为soap基于XML，可将结果直接写入XML文件。soap请求体如下
POST /WebServices/WeatherWS.asmx HTTP/1.1
Host: ws.webxml.com.cn
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://WebXml.com.cn/getWeather"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<getWeather xmlns="http://WebXml.com.cn/">
<theCityCode>string</theCityCode>
</getWeather>
</soap:Body>
</soap:Envelope>
