Android开发入门之发送XML数据和调用webservice
新建一个项目mobileAddressQuery，添加测试所需要的配置以及访问网络权限
将person.xml放到src目录下：
<?xml version="1.0" encoding="UTF-8"?>
<persons>
<person id="23">
<name>gaolei</name>
<age>23</age>
</person>
<person id="24">
<name>xiaoqiang</name>
<age>25</age>
</person>
</persons>
XmlTest.java：
package cn.leigo.test;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import cn.leigo.utils.StreamTool;
import android.test.AndroidTestCase;
import android.util.Log;
public class XmlTest extends AndroidTestCase {
private static final String TAG = "XmlTest";
public void testSendXML() throws Exception {
InputStream inputStream = this.getClass().getClassLoader()
.getResourceAsStream("person.xml");
byte[] data = StreamTool.read(inputStream);
String path = "http://192.168.1.100:8080/videonews/XmlServlet";
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setConnectTimeout(5000);
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.setRequestProperty("Content-Type", "text/html; charset=UTF-8");
conn.setRequestProperty("Content-Length", String.valueOf(data.length));
conn.getOutputStream().write(data);
if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
Log.d(TAG, "发送成功！");
} else {
Log.d(TAG, "发送失败！");
}
}
}
StreamTool.java
package cn.leigo.utils;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
public class StreamTool {
/**
* 读取流中的数据
*
* @param inputStream
* @return
* @throws IOException
*/
public static byte[] read(InputStream inputStream) throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
baos.write(buffer, 0, len);
}
inputStream.close();
return baos.toByteArray();
}
}
服务器端：
package cn.leigo.servlet;
import java.io.IOException;
import java.io.InputStream;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import cn.leigo.utils.StreamTool;
public class XmlServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
InputStream inputStream = request.getInputStream();
byte[] data = StreamTool.read(inputStream);
String xml = new String(data, "UTF-8");
System.out.println(xml);
}
}
打开http://www.webxml.com.cn/zh_cn/index.aspx,里面有很多供你调用的API，我们打开手机归属地查询http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx
以下是 SOAP 1.2 请求和响应示例。所显示的占位符需替换为实际值。
POST /WebServices/MobileCodeWS.asmx HTTP/1.1
Host: webservice.webxml.com.cn
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length
<?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>string</mobileCode>
<userID>string</userID>
</getMobileCodeInfo>
</soap12:Body>
</soap12:Envelope>
HTTP/1.1 200 OK
Content-Type: application/soap+xml; charset=utf-8
Content-Length: length
<?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>
<getMobileCodeInfoResponse xmlns="http://WebXml.com.cn/">
<getMobileCodeInfoResult>string</getMobileCodeInfoResult>
</getMobileCodeInfoResponse>
</soap12:Body>
</soap12:Envelope>
第一步:新建一个Android工程命名为mobileAddressQuery目录结构如下图:
第二步:修改activity_main.xml布局文件代码如下:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/mobile" />
<EditText
android:id="@+id/et_mobile"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="phone" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="query"
android:text="@string/query" />
<TextView
android:id="@+id/tv_address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
</LinearLayout>
strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">手机号归属地查询</string>
<string name="action_settings">Settings</string>
<string name="hello_world">Hello world!</string>
<string name="mobile">手机号码</string>
<string name="query">查询</string>
<string name="please_enter_mobile_number">请输入手机号码，最少前7位数字</string>
<string name="success">查询成功！</string>
<string name="fail">查询失败!</string>
<string name="error">查询出错！</string>
</resources>
第三步：建立web服务的xml ----->soap12.xml。
<?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>
</getMobileCodeInfo>
</soap12:Body>
</soap12:Envelope>
第四步：编写MianActivity类：
package cn.leigo.address;
import android.app.Activity;
import android.os.Bundle;
import android.text.TextUtils;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
import cn.leigo.service.AddressService;
public class MainActivity extends Activity {
private EditText mMobileEditText;
private TextView mAddressTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMobileEditText = (EditText) findViewById(R.id.et_mobile);
mAddressTextView = (TextView) findViewById(R.id.tv_address);
}
public void query(View v) {
String mobile = mMobileEditText.getText().toString();
if (!TextUtils.isEmpty(mobile)) {
try {
String address = AddressService.query(mobile);
mAddressTextView.setText(address);
Toast.makeText(this, R.string.success, Toast.LENGTH_SHORT)
.show();
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(this, R.string.fail, Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(this, R.string.please_enter_mobile_number,
Toast.LENGTH_SHORT).show();
}
}
}
业务类AddressService.java:
package cn.leigo.service;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;
import android.util.Xml;
import cn.leigo.utils.StreamTool;
public class AddressService {
/**
* 获取手机归属地
*
* POST /WebServices/MobileCodeWS.asmx HTTP/1.1 Host:
* webservice.webxml.com.cn Content-Type: application/soap+xml;
* charset=utf-8 Content-Length: length
*
* <?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>string</mobileCode> <userID>string</userID>
* </getMobileCodeInfo> </soap12:Body> </soap12:Envelope>
*
* @param mobile
* @return
* @throws IOException
* @throws XmlPullParserException
*/
public static String query(String mobile) throws IOException,
XmlPullParserException {
String soap = readSoap();
String soapEntity = soap.replaceAll("\\$mobile", mobile);
byte[] data = soapEntity.getBytes();
String path = "http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx";
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoOutput(true);
conn.setConnectTimeout(5000);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type",
"application/soap+xml;charset=utf-8");
conn.setRequestProperty("Content-Length", String.valueOf(data.length));
OutputStream outputStream = conn.getOutputStream();
outputStream.write(data);
outputStream.flush();
outputStream.close();
if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
return parseSOAP(conn.getInputStream());
}
return null;
}
/**
* HTTP/1.1 200 OK Content-Type: application/soap+xml; charset=utf-8
* Content-Length: length
*
* <?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>
* <getMobileCodeInfoResponse xmlns="http://WebXml.com.cn/">
* <getMobileCodeInfoResult>string</getMobileCodeInfoResult>
* </getMobileCodeInfoResponse> </soap12:Body> </soap12:Envelope>
*
*/
private static String parseSOAP(InputStream inputStream)
throws XmlPullParserException, IOException {
XmlPullParser parser = Xml.newPullParser();
parser.setInput(inputStream, "UTF-8");
int eventType = parser.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
switch (eventType) {
case XmlPullParser.START_TAG:
if ("getMobileCodeInfoResult".equals(parser.getName())) {
return parser.nextText();
}
break;
}
eventType = parser.next();
}
return null;
}
private static String readSoap() throws IOException {
InputStream inputStream = AddressService.class.getClassLoader()
.getResourceAsStream("soap12.xml");
byte[] data = StreamTool.read(inputStream);
return new String(data, "UTF-8");
}
}
工具类StreamTool：
package cn.leigo.utils;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
public class StreamTool {
/**
* 读取流中的数据
*
* @param inputStream
* @return
* @throws IOException
*/
public static byte[] read(InputStream inputStream) throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
baos.write(buffer, 0, len);
}
inputStream.close();
return baos.toByteArray();
}
}
最后别忘了在AndroidManifest.xml文件中添加权限：
<uses-permission android:name="android.permission.INTERNET" />
运行上述工程查看效果图:
