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。

三、Java使用SOAP调用webservice实例解析

参照：http://www.cnblogs.com/linjiqin/archive/2012/05/07/2488880.html

1.webservice提供方：http://www.webxml.com.cn/zh_cn/index.aspx
2.下面我们以“获得腾讯QQ在线状态”为例。
[http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx?op=qqCheckOnline] 点击前面的网址，查看对应参数信息。

3.Java程序

package com.test.qqwstest;
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.URL;
public class JxSendSmsTest {
public static void main(String[] args) {
sendSms();
}
/**

*/
public static void sendSms() {
try{
String qqCode = "2379538089";//qq号码
String urlString = "http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx";
String xml = JxSendSmsTest.class.getClassLoader().getResource("SendInstantSms.xml").getFile();
String xmlFile=replace(xml, "qqCodeTmp", qqCode).getPath();
String soapActionString = "http://WebXml.com.cn/qqCheckOnline";
URL url = new URL(urlString);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
File fileToSend = new File(xmlFile);
byte[] buf = new byte[(int) fileToSend.length()];
new FileInputStream(xmlFile).read(buf);
httpConn.setRequestProperty("Content-Length", String.valueOf(buf.length));
httpConn.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
httpConn.setRequestProperty("soapActionString", soapActionString);

httpConn.setDoOutput(true);
httpConn.setDoInput(true);
OutputStream out = httpConn.getOutputStream();
out.write(buf);
out.close();
byte[] datas=readInputStream(httpConn.getInputStream());
String result=new String(datas);
//打印返回结果
System.out.println("result:" + result);
}
catch(Exception e){
System.out.println("result:error!");
}
}
/**
* 文件内容替换
*
* @param inFileName 源文件
* @param from
* @param to
* @return 返回替换后文件
* @throws IOException

*/
public static File replace(String inFileName, String from, String to)
throws IOException, UnsupportedEncodingException {
File inFile = new File(inFileName);
BufferedReader in = new BufferedReader(new InputStreamReader(
new FileInputStream(inFile), "utf-8"));
File outFile = new File(inFile + ".tmp");
PrintWriter out = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(new FileOutputStream(outFile), "utf-8")));
String reading;
while ((reading = in.readLine()) != null) {
out.println(reading.replaceAll(from, to));
}
out.close();
in.close();
//infile.delete(); //删除源文件
//outfile.renameTo(infile); //对临时文件重命名
return outFile;
}
/**
* 从输入流中读取数据
* @param inStream
* @return
* @throws Exception
*/
public static byte[] readInputStream(InputStream inStream) throws Exception{
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len = 0;
while( (len = inStream.read(buffer)) !=-1 ){
outStream.write(buffer, 0, len);
}
byte[] data = outStream.toByteArray();//网页的二进制数据
outStream.close();
inStream.close();
return data;
}
}

4、SendInstantSms.xml文件如下，放在src目录下

<?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>
<qqCheckOnline xmlns="http://WebXml.com.cn/">
<qqCode>qqCodeTmp</qqCode>
</qqCheckOnline>
</soap:Body>
</soap:Envelope>
