通过HTTP协议发送XML数据并调用

来源：互联网发布：ios邪恶福利软件编辑：程序博客网时间：2024/05/22 04:32

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="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>

<mobileCode>$mobile</mobileCode>

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();

}

});

}
