Android:client通过HTTP连接server,完毕注冊并传送坐标信息

一、Main.xml

      主要是2个Button和一个TextView。“设备注冊”点击后即向server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server,经过定位算法处理后再从server传回修正坐标信息(因篇幅有限。本节暂不提坐标信息是怎样获取的)。以下的TextView用于实时显示状态信息。

其它的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="信息交互窗体" 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="设备注冊" /> <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serverIP地址。

getPostResult()方法传入的url为server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();
		// }
	}

	//无參数传递的
		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參数
	        BasicHttpParams httpParams = new BasicHttpParams();
			HttpConnectionParams.setConnectionTimeout(httpParams,10 * 1000);
			HttpConnectionParams.setSoTimeout(httpParams, 10 * 1000);

			//创建网络訪问处理对象
			HttpClient httpClient = new DefaultHttpClient(httpParams);
			try{
				//运行请求參数�?
				HttpResponse response = httpClient.execute(post);
				//推断是否请求成功
				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!

\"}"; } //有參数传递的 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); //创建网络訪问处理对象 HttpClient httpClient = new DefaultHttpClient(httpParams); try{ //运行请求參数�? HttpResponse response = httpClient.execute(post); //推断是否请求成功 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!

\"}"; } }


三、注冊信息的传送

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server回馈的信息

(需自行下载并加入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");
		}








3、因http耗时需将设备注冊与左边信息传送放在异步线程里来运行,否则会报异常


//注冊
    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");         }     }         }
