我正在使用IntentServices将数据发布到服务器，但我不知道如何在IntentService中获得json格式的响应，以及我们如何能够发现这个IntentService在后台运行，并根据响应执行某些操作。如何从android中的Intent服务中的服务器获取Json响应？

public class CDealIntentService extends IntentService {

private static final String s_szDealDetailUrl = "http://202.121.144.133:8080/ireward/rest/json/metallica/getDealDetailInJSON";

private static String s_szresult = "";

Context ctx;

String m_szMobileNumber, m_szEncryptedPassword;

/**

* Creates an IntentService. Invoked by your subclass's constructor.

*

* // * @param name Used to name the worker thread, important only for debugging.

*/

public CDealIntentService() {

super("CDealIntentService");

}

@Override

protected void onHandleIntent(Intent intent) {

Context ctx = getApplicationContext();

CLoginSessionManagement m_oSessionManagement = new CLoginSessionManagement(ctx);

HashMap user = m_oSessionManagement.getLoginDetails();

m_szMobileNumber = user.get(CLoginSessionManagement.s_szKEY_MOBILE);// getting mobile from saved preferences..........

m_szEncryptedPassword = user.get(CLoginSessionManagement.s_szKEY_PASSWORD);// getting password from shared preferences...

InputStream inputStream;

try {

// 1. create HttpClient

HttpClient httpclient = new DefaultHttpClient();

// 2. make POST request to the given URL

HttpPost httpPost = new HttpPost(s_szDealDetailUrl);

String json;

// 3. build jsonObject

JSONObject jsonObject = new JSONObject();

jsonObject.put("agentCode", m_szMobileNumber);// mobile Number

jsonObject.put("pin", m_szEncryptedPassword);// password

//noinspection AccessStaticViaInstance

jsonObject.put("dealcode", CDealCode.getInstance().getS_szDealCode());// dealCode

// 4. convert JSONObject to JSON to String

json = jsonObject.toString();

// 5. set json to StringEntity

StringEntity se = new StringEntity(json);

// 6. set httpPost Entity

httpPost.setEntity(se);

// 7. Set some headers to inform server about the type of the content

// httpPost.setHeader("Accept", "application/json"); ///not required

httpPost.setHeader("Content-type", "application/json");

// 8. Execute POST request to the given URL

HttpResponse httpResponse = httpclient.execute(httpPost);

HttpEntity entity = httpResponse.getEntity();

// 9. receive response as inputStream

inputStream = entity.getContent();

System.out.print("InputStream...." + inputStream.toString());

System.out.print("Response...." + httpResponse.toString());

StatusLine statusLine = httpResponse.getStatusLine();

System.out.print("statusLine......" + statusLine.toString());

Log.d("resp_body", resp_body.toString());

int statusCode = statusLine.getStatusCode();

if (statusCode == 200) {

// 10. convert inputstream to string

s_szresult = CJsonsResponse.convertInputStreamToString(inputStream);

} else

s_szresult = "Did not work!";

} catch (Exception e) {

Log.d("InputStream", e.getLocalizedMessage());

}

System.out.println("Result" + s_szresult);

}

}下面的代码

你可以采取一些SharedPreference变量为和可检查服务是否正在运行与否。否则有几种方法检查服务是否正在运行 –

其他查询是什么意思？ –
