使用URLConnection调用webservice与使用ajax调用webservice的主要的差别就在于前者是使用java语言来构造http请求&＃xff0c;

而后者则是使用js语言来构造http请求。这两种方式所实现的功能其实是一样的&＃xff0c;只是实现的形式不同而已····················

1、服务器端代码可以参考使用jdk来调用webservice

2、客户端的代码如下

App

package com.njupt.webservice.urlConnection;import java.io.InputStream;import java.io.OutputStream;import java.net.HttpURLConnection;import java.net.URL;public class App { public static void main(String[] args) throws Exception {  URL wsUrl &＃61; new URL("http://127.0.0.1:6790/hello");    HttpURLConnection conn &＃61;  (HttpURLConnection) wsUrl.openConnection();    conn.setDoInput(true);//有输入  conn.setDoOutput(true);//有输出  conn.setRequestMethod("POST");  conn.setRequestProperty("Content-Type", "text/xml;charset&＃61;utf-8");      //要想在双引号中再使用双引号,则可以使用转义符\将双引号转义  String soap &＃61; ""&＃43;        "章泽天是我的女神 ";    OutputStream os &＃61; conn.getOutputStream();  os.write(soap.getBytes());    InputStream is &＃61; conn.getInputStream();    byte[] b &＃61; new byte[1024];  int len &＃61; 0;  String s &＃61; "";    while( (len &＃61; is.read(b)) !&＃61; -1){   s &＃43;&＃61; new String(b,0,len,"UTF-8");  }    System.out.println(s);    os.close();  is.close();  conn.disconnect();       }}
