通过HTTP协议发送XML数据并调用

 

1、发送xml数据给服务器 ,并非以请求参数方式发送：

http://192.168.1.10:8080/video/manage.do?xml=....

 

服务器端代码：VideoManageAction.java

public ActionForward getXML(ActionMapping mapping, ActionForm form,            HttpServletRequest request, HttpServletResponse response)            throws Exception {        InputStream inStream = request.getInputStream();        byte[] data = StreamTool.readInputStream(inStream);        String xml = new String(data, "UTF-8");        System.out.println(xml);        return mapping.findForward("result");     }

 

J2SE编写客户端向web服务器发生xml数据

public static void main(String[] args) throws Exception {     String path="http://192.168.1.100:8080/videoweb/video/manage.do?method=getXML";     String xml="中国30";            byte[] data = xml.getBytes("UTF-8");//得到了xml的实体数据     URL url = new URL(path);     HttpURLConnection conn = (HttpURLConnection) url.openConnection();     conn.setConnectTimeout(5000);     conn.setRequestMethod("POST");     conn.setDoOutput(true);     conn.setRequestProperty("Content-Type", "text/xml;charset=UTF-8");     conn.setRequestProperty("Content-Length", String.valueOf(data.length));            OutputStream outStream =  conn.getOutputStream();     outStream.write(data);     outStream.flush();     outStream.close();     System.out.println(conn.getResponseCode()); }

 

2、发送SOAP数据给服务器调用webservice，实现手机号归属地查询

访问网址www.webxml.com.cn ，浏览各种web service，打开手机号码归属地查询并进行解释。

 

实验步骤：

创建android工程MobileBelong，设置网络访问权限。

 

资源

"hello">Hello World, MainActivity!     "app_name">手机号归属地查询     "mobile">手机号     "button">查询     "error">网络连接失败

布局

android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="@string/mobile" />               android:id="@+id/mobile"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="13472283596" />               android:id="@+id/button"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/button" />               android:id="@+id/result"         android:layout_width="fill_parent"         android:layout_height="wrap_content" />

 

在src目录下创建mobilesoap.xml，并将网址文档中提供的代码复制其中，如下

"1.0" encoding="utf-8"?> "http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">       "http://WebXml.com.cn/">       $mobile       占位符

 

业务类：MobileService

注意访问目标地址是：

http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx

可以有协议中得到。

 

package cn.class3g.service; … public class MobileService {   public static String getMobileAddress(String mobile) throws Exception {          InputStream inStream = MobileService.class.getClassLoader()               .getResourceAsStream("mobilesoap.xml");        byte[] data = StreamTool.readInputStream(inStream);        String xml = new String(data);        String soap = xml.replaceAll("\\$mobile", mobile);          /**         * 正则表达式$为特殊正则中的特殊符号须转义，即\$mobile         * 而\为字符串中的特殊符号，所以用两个反斜杠，即"\\$"         */        String path = "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";        data = soap.getBytes();// 得到了xml的实体数据        URL url = new URL(path);        HttpURLConnection conn = (HttpURLConnection) url.openConnection();        conn.setConnectTimeout(5 * 1000);        conn.setRequestMethod("POST");        conn.setDoOutput(true);        conn.setRequestProperty("Content-Type",               "application/soap+xml; charset=utf-8");        conn.setRequestProperty("Content-Length", String.valueOf(data.length));        OutputStream outStream = conn.getOutputStream();        outStream.write(data);        outStream.flush();        outStream.close();        if (conn.getResponseCode() == 200) {            InputStream responseStream = conn.getInputStream();            return parseXML(responseStream);        }        return null;     }       /**      * 解析返回xml数据      *      * @param responseStream      * @return      * @throws Exception      */     private static String parseXML(InputStream responseStream) throws Exception {        XmlPullParser parser = Xml.newPullParser();        parser.setInput(responseStream, "UTF-8");        int event = parser.getEventType();        while (event != XmlPullParser.END_DOCUMENT) {            switch (event) {            case XmlPullParser.START_TAG:               if ("getMobileCodeInfoResult".equals(parser.getName())) {                   return parser.nextText();               }               break;            }            event = parser.next();        }        return null;     } }

 

工具类StreamTool

package cn.class3g.utils; … public class StreamTool {     /**      * 从输入流读取数据      * @param inStream      * @return      * @throws Exception      */     public static byte[] readInputStream(InputStream inStream) throws Exception{        ByteArrayOutputStream outSteam = new ByteArrayOutputStream();        byte[] buffer = new byte[1024];        int len = 0;        while( (len = inStream.read(buffer)) !=-1 ){            outSteam.write(buffer, 0, len);        }        outSteam.close();        inStream.close();        return outSteam.toByteArray();     } }

 

Activity类MobileBelongActivity

package cn.class3g.mobile; … public class MobileBelongActivity extends Activity {       private static final String TAG = "MainActivity";     private EditText mobileText;     private TextView resultView;       @Override     public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);          mobileText = (EditText) this.findViewById(R.id.mobile);        resultView = (TextView) this.findViewById(R.id.result);        Button button = (Button) this.findViewById(R.id.button);        button.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {               String mobile = mobileText.getText().toString();               try {                   String address = MobileService.getMobileAddress(mobile);                   resultView.setText(address);               } catch (Exception e) {                   Log.e(TAG, e.toString());                   Toast.makeText(MobileBelongActivity.this, R.string.error, 1).show();               }            }        });     } }
