C#/Java 调用WSDL接口及方法

一、C#利用vs里面自带的“添加web引用”功能:
1.首先需要清楚WSDL的引用地址
  如:http://www.webxml.com.cn/Webservices/WeatherWebService.asmx

2.在.Net项目中,添加web引用。

3.在弹出页面中,输入URL->点击点击绿色图标(前往)按钮->自定义引用名->点击添加引用

4.添加成功,查看类中可调用的方法:

5.在项目中,调用wsdl中的方法。
        private void button1_Click(object sender, EventArgs e)
        {
            testWS2.Weather.WeatherWebService objWeather = new Weather.WeatherWebService(); 
            string strCityName = "上海";
            string[] arrWeather = objWeather.getWeatherbyCityName(strCityName);
            MessageBox.Show(arrWeather[10]);
        }
6.注意事项:
(1)如果看不到第四步类,点击项目上面的“显示所有文件”图标按钮;
(2)如果目标框架.NET Framework 4.0生成的第四步类无可调用的方法,可以试一下“.NET Framework 2.0”;
二、C# .Net采用GET/POST/SOAP方式动态调用WebService的简易灵活方法
参考:http://blog.csdn.net/chlyzone/article/details/8210718
这个类有三个公用的方法: QuerySoapWebService为通用的采用Soap方式调用WebService,QueryGetWebService采用GET方式调用,QueryPostWebService采用POST方式调用,后两个方法需要WebService服务器支持相应的调用方式。三个方法的参数和返回值相同:URL为Webservice的Url地址(以.asmx结尾的);MethodName为要调用的方法名称;Pars为参数表,它的Key为参数名称,Value为要传递的参数的值,Value可为任意对象,前提是这个对象可以被xml序列化。注意方法名称、参数名称、参数个数必须完全匹配才能正确调用。第一次以Soap方式调用时,因为需要查询WSDL获取xmlns,因此需要时间相对长些,第二次调用不用再读WSDL,直接从缓存读取。这三个方法的返回值均为XmlDocument对象,这个返回的对象可以进行各种灵活的操作。最常用的一个SelectSingleNode方法,可以让你一步定位到Xml的任何节点,再读取它的文本或属性。也可以直接调用Save保存到磁盘。采用Soap方式调用时,根结点名称固定为root。
这个类主要是利用了WebRequest/WebResponse来完成各种网络查询操作。为了精简明了,这个类中没有添加错误处理,需要在调用的地方设置异常捕获。
