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=<xml>....</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="<?xml version=\"1.0\" encoding=\"UTF-8\"?><persons><person id=\"23\"><name>中国</name><age>30</age></person></persons>"; 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

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

布局

<TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/mobile" /> <EditText android:id="@+id/mobile" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="13472283596" /> <Button android:id="@+id/button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button" /> <TextView 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

<?xml version="1.0" encoding="utf-8"?> <soap12:Envelope xmlns:xsi="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"> <soap12:Body> <getMobileCodeInfo xmlns="http://WebXml.com.cn/"> <mobileCode>$mobile</mobileCode> <userID></userID> 占位符 </getMobileCodeInfo> </soap12:Body> </soap12:Envelope>

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(); } } }); } }
