android通过C#的webservice与服务端进行数据通信(sqlserver)

这两天由于工作需要，学习了下android通过C#的webservice与服务端进行数据通信(sqlserver)。中间遇到几个问题，总结下，以备后期使用时注意。

Android端调用webservice的代码：

/**
 * 上传设备状态信息信息
 *
 * @param data 打包好的数据
 * @return 成功与否的相关字符串
 */
publicstatic StringuploadLocation(String data) {
    METHOD_NAME ="UploadLocation";
    try {
        SoapObject soapObject = new SoapObject(NAMESPACE,METHOD_NAME);
        PropertyInfo propertyInfo = new PropertyInfo();
        propertyInfo.setName("LocationInfo");
        propertyInfo.setValue(data);
       soapObject.addProperty(propertyInfo);
        SoapSerializationEnvelopeenvelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.dotNet =true;
       envelope.setOutputSoapObject(soapObject);
        HttpTransportSE httpTranstation =new HttpTransportSE(URL);
        httpTranstation.debug= true;
        httpTranstation.call(NAMESPACE+ METHOD_NAME, envelope);
        Object result = (Object)envelope.getResponse().toString();
        if (result !=null) {
            Log.i("WebserviceControlClass", result.toString());
            return result.toString();
        }
        return "返回数据为空";
    } catch (Exception e) {
        e.printStackTrace();
        Log.i("WebserviceControlClass","设备信息上传出现异常"+ e.toString());
        return "出现异常";
    }
}

 

需要注意的地方:

1.   propertyInfo.setName("LocationInfo");参数要与webservice方法中参数保持一致，否则获取不到数据。

2.      envelope.dotNet= true;我用的是dotwebservice的协议，并且用的rpc方式所以，这里要用true.

3.      httpTranstation.debug= true;需要用调试模式，所以为true

 

 

因为与服务器之间进行通信，是一个耗时的操作，所最后不要再主线程中直接写访问代码。应该通过异步的方式，请求数据。

 

importandroid.os.AsyncTask;/** * Created by ZHao on 2016/4/15. */public class WebServiceTask extends AsyncTask<String, Integer, String> {    public WebServiceTask() {    }    @Override    protected void onPreExecute() {    }    @Override    protected String doInBackground(String... params) {        return WebserviceControlClass.uploadLocation(params[0]);//这里返回webServices请求的值。    }    @Override    protected void onProgressUpdate(Integer... progress) {    }    @Override    protected void onPostExecute(String result) {    }}

然后配合handler实现数据的收发。

/** * 处理设备状态信息 上传和回掉结果 */public Handler handler = new Handler() {    @Override    public void handleMessage(Message msg) {        if (msg.what == 0) {            WebServiceTask task = new WebServiceTask();            String result = "";            try {                task.execute((String) msg.obj); //设置请求参数                result = task.get(5000, TimeUnit.MILLISECONDS); //获取返回值，设置超时时间。            } catch (InterruptedException e) {                e.printStackTrace();                result = "出现异常InterruptedException";            } catch (ExecutionException e) {                e.printStackTrace();                result = "出现异常ExecutionException";            } catch (TimeoutException e) {                e.printStackTrace();                result = "出现异常TimeoutException";            } catch (Exception e) {                result = "出现异常 Exception";            }            LogTools.i(TAG, result);        }    }};

 

因为我需要将一个对象传递到服务端，android调用webservice传输复杂对象，该怎么做呢?

具体的实现方式如下。

首先是android具体操作代码,这里通过handler将locationData传递给异步类，进行数据上传。

dbDeviceStateClass = new DbDeviceStateClass();dbDeviceStateClass.setDevice_id(CommonUtil.getDeviceId(this));//设备idLogTools.i(TAG, CommonUtil.getDeviceId(this));dbDeviceStateClass.setDevice_state_current_lat(String.valueOf(geoLat));//精度dbDeviceStateClass.setDevice_state_current_lon(String.valueOf(geoLng));//纬度dbDeviceStateClass.setDevice_city(location.getCity());//所在城市dbDeviceStateClass.setDevice_province(location.getProvince());//所在省locationData = ConvertForJsonModelControl.ConvertToJsonForDeviceState(dbDeviceStateClass);Message msg = handler.obtainMessage();msg.what = 0;msg.obj = locationData;handler.sendMessageDelayed(msg, 10);

需要注意的是，传递的对象，android和服务端需要保持一致，在android将数据打包成JSONObject，在服务端在解析出来，服务端代码在下面贴出。

** * 将设备状态信息实体类转换为json对象 * @param dbDeviceStateClass * @return */public static String ConvertToJsonForDeviceState(DbDeviceStateClass dbDeviceStateClass) {    String jsonStr = "";    JSONObject modelJsonObject = new JSONObject();    try {        modelJsonObject.put("device_state_id", 0);        modelJsonObject.put("device_id", dbDeviceStateClass.getDevice_id());        modelJsonObject.put("user_name", dbDeviceStateClass.getUser_name());        modelJsonObject.put("device_city", dbDeviceStateClass.getDevice_city());        modelJsonObject.put("device_province", dbDeviceStateClass.getDevice_province());        modelJsonObject.put("device_location", dbDeviceStateClass.getDevice_location());        modelJsonObject.put("device_state_current_speed", dbDeviceStateClass.getDevice_state_current_speed());        modelJsonObject.put("device_state_update_time", dbDeviceStateClass.getDevice_state_update_time());        modelJsonObject.put("device_state_connect_net", dbDeviceStateClass.getDevice_state_connect_net());        modelJsonObject.put("device_state_current_lat", dbDeviceStateClass.getDevice_state_current_lat());        modelJsonObject.put("device_state_current_lon", dbDeviceStateClass.getDevice_state_current_lon());        jsonStr = modelJsonObject.toString();    } catch (JSONException e) {        e.printStackTrace();    }    return jsonStr;}

接下来是服务端sebservice的具体方法代码,其中这个db_table_device_state 数据类要和android端的DbDeviceStateClass数据类保持一致，才能通过

device_state=(db_table_device_state)jsonSerializer.Deserialize(newJsonTextReader(strReader),typeof(db_table_device_state));将JSONObject数据解析出来。

/// <summary>/// 保存设备状态到数据库/// </summary>/// <param name="LocationInfo"></param>/// <returns></returns>[WebMethod]public string UploadLocation(string LocationInfo)        {        string strJson = "";        db_table_device_state device_state = null;        try {        using (var db = new hudProjecterDBEntities())        {        JsonSerializer jsonSerializer = new JsonSerializer();        StringReader strReader = new StringReader(LocationInfo);        device_state = (db_table_device_state)jsonSerializer.Deserialize(new JsonTextReader(strReader), typeof(db_table_device_state));        if (device_state != null)        {        var mdevice = db.db_table_device.FirstOrDefault(p => p.device_id == device_state.device_id);        strJson = "mdevice:" + mdevice;        if (mdevice != null)        {        db_table_device_state mdevicestate = new db_table_device_state();        mdevicestate.device_state_current_lat = device_state.device_state_current_lat;        mdevicestate.device_state_current_lon = device_state.device_state_current_lon;        mdevicestate.device_state_connect_net = device_state.device_state_connect_net;        mdevicestate.device_state_update_time = DateTime.Now;        mdevicestate.device_state_current_speed = device_state.device_state_current_speed;        db.db_table_device_state.Add(mdevicestate);        db.SaveChanges();        strJson = "[{\"Code\":\"200\",\"Message\":\"操作成功!\"}]";        }        }        }        }        catch (Exception ex)        {        strJson = "[{\"Code\":\"500\",\"Message\":\"服务器出错!\"}]";        }        return strJson;        }

好了，整体流程代码和需要注意的问题都在这里了。吼吼！！
