Android:客户端通过HTTP连接服务器，完成登记并传送坐标信息

一、Main.xml

      主要是2个Button和一个TextView。“设备注册”点击后即向服务器发送设备的MAC、HolderName等信息；“坐标传送”则输送设备从iBeacon获取的坐标信息到服务器，经过定位算法处理后再从服务器传回修正坐标信息（因篇幅有限，本节暂不提坐标信息是如何获取的）。下面的TextView用于实时显示状态信息。其他的View主要用于实际调试。

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"	android:orientation="vertical"	android:layout_width="fill_parent"	android:layout_height="fill_parent">	<LinearLayout 		android:orientation="horizontal" android:layout_width="fill_parent"		android:layout_height="wrap_content" android:layout_marginTop="10dp">		<TextView android:layout_width="wrap_content"			android:layout_height="wrap_content" android:text="信息交互窗口" android:textSize="16dp"			android:layout_marginRight="10dp" />		<EditText android:id="@+id/tvEdit" android:layout_width="fill_parent" android:text=""			android:layout_height="wrap_content" />	</LinearLayout>	<Button android:id="@+id/btnGetQuery" android:layout_width="fill_parent"		android:layout_height="wrap_content" android:text="设备注册" />	<Button android:id="@+id/btnPostQuery" android:layout_width="fill_parent"		android:layout_height="wrap_content" android:text="坐标传送" />	<TextView android:id="@+id/tvQueryResult"		android:layout_width="fill_parent" android:layout_height="wrap_content" /></LinearLayout>

二、建立HTTP连接

1、NetworkService类用于建立HTTP连接。

2、url_ip为服务器IP地址，

getPostResult()方法传入的url为服务器定义的action，本文为"equipment_Register_VIPRegister_n.action"

package net.blogjava.mobile;import java.io.UnsupportedEncodingException;import java.util.List;import org.apache.http.HttpResponse;import org.apache.http.HttpStatus;import org.apache.http.NameValuePair;import org.apache.http.client.HttpClient;import org.apache.http.client.entity.UrlEncodedFormEntity;import org.apache.http.client.methods.HttpPost;import org.apache.http.impl.client.DefaultHttpClient;import org.apache.http.params.BasicHttpParams;import org.apache.http.params.HttpConnectionParams;import org.apache.http.util.EntityUtils;import android.util.Log;public class NetworkService {	private static String TAG = "NetworkService";		//private static String url_ip = ServerUrl.SERVER_ADRESS+"UserInfoServlet?";	private static String url_ip = "http://192.168.1.231:8080/indoor/";		/**	 * 释放资源	 */	public static void cancel() {		Log.i(TAG, "cancel!");		// if(conn != null) {		// conn.cancel();		// }	}	//无参数传递的		public static String getPostResult(String url){						url = url_ip + url;			//创建http请求对象			HttpPost post = new HttpPost(url);						//创建HttpParams以用来设置HTTP参数	        BasicHttpParams httpParams = new BasicHttpParams();			HttpConnectionParams.setConnectionTimeout(httpParams,10 * 1000);			HttpConnectionParams.setSoTimeout(httpParams, 10 * 1000);			//创建网络访问处理对象			HttpClient httpClient = new DefaultHttpClient(httpParams);			try{				//执行请求参数??				HttpResponse response = httpClient.execute(post);				//判断是否请求成功				if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {					//获得响应信息					String content = EntityUtils.toString(response.getEntity());					return content;				} else {					//网连接失败，使用Toast显示提示信息									}							}catch(Exception e) {				e.printStackTrace();				return "{\"status\":405,\"resultMsg\":\"网络超时！\"}";			} finally {				//释放网络连接资源				httpClient.getConnectionManager().shutdown();			}			return "{\"status\":405,\"resultMsg\":\"网络超时！\"}";					}	   //有参数传递的		public static String getPostResult(String url, List<NameValuePair> paramList){			UrlEncodedFormEntity entity = null;			try {				entity = new UrlEncodedFormEntity(paramList,"utf-8");			} catch (UnsupportedEncodingException e1) {				// TODO Auto-generated catch block				e1.printStackTrace();			}						//创建http请求对象			HttpPost post = new HttpPost(url);			BasicHttpParams httpParams = new BasicHttpParams();						HttpConnectionParams.setConnectionTimeout(httpParams, 10 * 1000);			HttpConnectionParams.setSoTimeout(httpParams, 10 * 1000);			post.setEntity(entity);			//创建网络访问处理对象			HttpClient httpClient = new DefaultHttpClient(httpParams);			try{				//执行请求参数??				HttpResponse response = httpClient.execute(post);				//判断是否请求成功				if(response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {					//获得响应信息					String content = EntityUtils.toString(response.getEntity(),"UTF-8");					return content;				} else {					//网连接失败，使用Toast显示提示信息									}							}catch(Exception e) {				e.printStackTrace();				return "{\"status\":405,\"resultMsg\":\"网络超时！\"}";			} finally {				//释放网络连接资源				httpClient.getConnectionManager().shutdown();			}			return "{\"status\":405,\"resultMsg\":\"网络超时！\"}";					}}

1、定义List<NameValuePair>：

List<NameValuePair> paramList = new ArrayList<NameValuePair>();			paramList.add(new BasicNameValuePair("headTage","device"));			paramList.add(new BasicNameValuePair("idmac",IDMAC));			paramList.add(new BasicNameValuePair("model",MODEL));			paramList.add(new BasicNameValuePair("holdername",HOLDERNAME));

2、调用NetworkService类里面的getPostResult()方法：

String str ="";str = NetworkService.getPostResult(url, paramList);

3、Json解析服务器回馈的信息

（需自行下载并添加json的包）

import org.json.JSONArray;import org.json.JSONException;import org.json.JSONObject;import org.json.JSONTokener;

try {			JSONTokener jsonParser = new JSONTokener(result);			JSONObject responseobj = (JSONObject) jsonParser.nextValue(); 			if("failed".equals(responseobj.getString("errorMsg")))			{			tvQueryResult.setText(responseobj.getString("resul"));					//closeHeaderOrFooter(true);				}				else				{<pre name="code" class="java">                                 tvQueryResult.setText("没有数据");				}						else {<pre name="code" class="java"><pre name="code" class="java">                                 tvQueryResult.setText("数据获取失败");		}		} catch (Exception e) {<pre name="code" class="java"><pre name="code" class="java"><pre name="code" class="java"><pre name="code" class="java">                                 tvQueryResult.setText("数据获取失败");		}

//注册    class RegisterAsyncTask extends AsyncTask<String, Integer, String> {        Context myContext;        TextView tvQueryResult = (TextView) findViewById(R.id.tvQueryResult);        public RegisterAsyncTask(Context context) {            myContext = context;        }        @Override        protected String doInBackground(String... params) {            // TODO Auto-generated method stub            try {                resultData = InitData();                Thread.sleep(1000);             } catch (Exception e) {            }            return resultData;        }        @Override        protected void onPreExecute() {        }       protected String InitData() {            String IDMAC=getLocalMacAddress();            String MODEL = android.os.Build.MODEL==null ?"未知":android.os.Build.MODEL;            String HOLDERNAME = android.os.Build.USER==null ?"未知":android.os.Build.USER;            String str ="";            String url = "http://192.168.1.226:8080/indoor/equipment_Register_VIPRegister_n.action";            List<NameValuePair> paramList = new ArrayList<NameValuePair>();            paramList.add(new BasicNameValuePair("headTage","device"));            paramList.add(new BasicNameValuePair("idmac",IDMAC));            paramList.add(new BasicNameValuePair("model",MODEL));            paramList.add(new BasicNameValuePair("holdername",HOLDERNAME));            str = NetworkService.getPostResult(url, paramList);            Log.i("msg", str);            return str;        }            protected void onPostExecute(String result) {                        try {            JSONTokener jsonParser = new JSONTokener(result);            JSONObject responseobj = (JSONObject) jsonParser.nextValue();             if("failed".equals(responseobj.getString("errorMsg")))            {            tvQueryResult.setText(responseobj.getString("resul"));                }            else {                tvQueryResult.setText("数据获取失败");        }        } catch (Exception e) {                tvQueryResult.setText("数据获取失败");        }    }        }
