java如何利用webservice得到天气预报?

[danier_sky]

请问如何利用webservice得到天气预报 ,股票,列车,航班等信息?

本人初学webservice,不明白如何应用,希望大家多多帮助,举例说明

[ytuwlg]

找到wsdl地址后：
可以使用netBeans 生成客户端存根
然后在程序中调用存根比较方便

[danier_sky]

netBeans 是什么？

不能贴图简单说下哈
我用myeclipse
new - Web Service -Web Service Client

选择自己的项目
Service Definition 选择
WSDL URL:http://www.webservicex.net/globalweather.asmx?WSDL

选择Java Source 和Java package

Finish之后

自动在Java package生成两个文件GlobalWeatherClient和GlobalWeatherSoap
一个包net.webservicex里面有
GetCitiesByCountry
GetCitiesByCountryResponse
GetWeather
GetWeatherResponse
ObjectFactory
package-info
几个类


打开GlobalWeatherClient类在 main 里添加 System.out.println(service.getCitiesByCountry("China"));
运行就可以从webservice获得China的所有城市,其他的获得某个城市天气预报函数也都通过GlobalWeatherSoap中相应函数调用就可以了.

返回的数据就是xml格式的,剩下的工作就是通过DOM解析xml显示到页面上了,跟webservice没有关系了

可以用axis自动生成客户端，具体怎么写找Apache的资料。最近打算写一点儿这方面的东西。

[danier_sky]

嗯啊,我现在就想用axis
try
{
String endpoint ="http://www.wopos.com/webservice/Weather.asmx?wsdl";
Service service = new Service();
Call call = (Call) service.createCall();

call.setTargetEndpointAddress( new java.net.URL(endpoint) );
call.setOperationName(new QName("http://tempuri.org/", "getWeather"));

call.setUseSOAPAction(true);
call.setSOAPActionURI("http://tempuri.org/getWeather");

String ret = (String) call.invoke( new Object[] { "武汉" } );

System.out.println("Sent ’Hello!’, got ’" + ret + "’");
} catch (Exception e) {
System.out.println(e.toString());
}
结果报错了:
System.Web.Services.Protocols.SoapException: 服务器无法处理请求。 ---> System.NullReferenceException: 未将对象引用设置到对象的实例。
在 Weather.getWeather(String mCity)
--- 内部异常堆栈跟踪的结尾 ---

不知哪里错了,是否漏掉了什么...

[idilent]

生成了一个，不过代码超级复杂。

这个是getCitiesByCountry返回的数据，输入的国家名字china。

[danier_sky]

call.setOperationName(new QName("http://tempuri.org/", "getWeather")); //肯定是错的。

请问QName()中的两个参数是什么意思？

call.setSOAPActionURI("http://tempuri.org/getWeather");//肯定是错的。

这句有又什么意思？

[idilent]

你用的axis版本是多少？

而且在你的代码中

try
{
String endpoint ="http://www.wopos.com/webservice/Weather.asmx?wsdl";
Service service = new Service();
Call call = (Call) service.createCall();

call.setTargetEndpointAddress( new java.net.URL(endpoint) );
call.setOperationName(new QName("http://tempuri.org/", "getWeather")); //肯定是错的。

call.setUseSOAPAction(true);
call.setSOAPActionURI("http://tempuri.org/getWeather");//肯定是错的。

String ret = (String) call.invoke( new Object[] { "武汉" } );//用拼音。

System.out.println("Sent ’Hello!’, got ’" + ret + "’"); //sent的是wuhuan
} catch (Exception e) {
System.out.println(e.toString());
}

这个在新建项目时，是不是只能填本地的，不能填网络上的啊，我的填了http://www.webservicex.net/globalweather.asmx?WSDL就不能进行下一步了！
