使用URL工具类调用webservice接口（soap）与http接口的实现方式

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;

public class SoapTest {

public void testPost(String urlStr,String data) {
try {
//创建指定链接的url对象
URL url = new URL(urlStr);
//建立到url对象之间的链接
HttpURLConnection con = (HttpURLConnection) url.openConnection();
//如果打算使用 URL 连接进行输出，则将 DoOutput 标志设置为 true
con.setDoOutput(true);
//设置第一次请求的数据内容不被存储
con.setRequestProperty("Pragma:", "no-cache");
//设置请求的数据内容不被存储
con.setRequestProperty("Cache-Control", "no-cache");
//设置请求的字符集编码格式,如果不指定，则默认采用16进制的字符集编码格式
con.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");
//构造向指定链接写入数据的的输出流
OutputStreamWriter out = new OutputStreamWriter(con.getOutputStream());
//获取xml数据
String xmlInfo = getXmlInfo(data);
//向指定链接写入数据
out.write(new String(xmlInfo));
out.flush();
out.close();
//将从服务端返回的数据读取到内存中
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
String line = "";
//构造一个空的StringBuffer对象，用于存储内存中的数据
StringBuffer buf = new StringBuffer();
for (line = br.readLine(); line != null; line = br.readLine()) {
//由于服务端返回的数据的字符集编码有可能不是utf-8,需要对返回的数据通过指定的字符集进行解码
buf.append(new String(line.getBytes(),"UTF-8"));
}

//获取服务端返回的HttpCode
  int httpCode = con.getResponseCode();
  System.out.println("HttpCode:"+httpCode+"  "+map.get("msgType")+"接口:"+buf.toString());
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
//处理xml数据
public static String getXmlInfo(String data){
//对webservice接口进行加密(SHA-1加密)
SoapKey soapKey = new SoapKey();
String key=soapKey.getMessageDigest(data, "SHA-1");
//处理传输数据的"<"与">"字符
String str = new String(data.replace("<","&lt;")).replace(">","&gt;");
