问题描述
我有一个方法，从我从web服务在Android中使用HTTP POST获取数据。
I have a method from which I am fetching the data from webservice using http post in android.
我的code是，
public class PropertyRequestService {
static String result;
PropertiesList localProperty = new PropertiesList();
List<PropertiesList> Properties;
List<PropertiesList> PropertiesRS;
public List<PropertiesList> getAllPropertiesStuff() {
try {
HttpClient client = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"Here Given Webservice URL");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs
.add(new BasicNameValuePair("string", "value"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(httppost);
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
String response1= convertStreamToString(instream);
// Closing the input stream will trigger connection release
instream.close();
//result = EntityUtils.toString(entity);
Log.i("RESPONSE=", response1);
JSONObject json = new JSONObject(response1);
PropertiesRS.add(SplitResult(json));
}
} catch (Exception e1) {
e1.printStackTrace();
}
return PropertiesRS;
}
public static String convertStreamToString(InputStream instream) {
BufferedReader reader = new BufferedReader(new InputStreamReader(instream));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
instream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
这是logcat的，

我的web服务返回的数据格式，
My webservice returns the data in this format,

我不知道为什么这个异常正在提高。
I dont know the why this exception is being raised.
我不能送JSON格式数据的应用程序更改由于客户要求的限制。
I cannot change the application to send data in json format due to the restriction of client requirements.
如何转换在Android中，以JSON对象的反应如何？这是吃了我宝贵的时间，而不是进一步进行。我在这里停留。
How to convert the response to json object in android? This is eating away my valuable time and not to proceed further. I am stuck here.
任何想法或建议，请！
Any idea or suggestions please!
在此先感谢。
推荐答案
当你得到JSON响应覆盖XML标签，你必须写一个逻辑，这将使你的JSON数据。
As you are getting JSON response covered by XML tag, you have to write a logic that will give you that JSON data.
/**
* To fetch JSON Text between XML tags
* For example:
* <string xmlns="http://schemas.microsoft.com/2003/10/Serialization/"> JSON Response text </string>
* @param response
* @return
*/
public String getJSONString(HttpResponse response) {
try {
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(response.getEntity().getContent());
NodeList nl = doc.getElementsByTagName("string");
Node n = nl.item(0);
String str = n.getFirstChild().getNodeValue();
System.out.println("Node value : " + str);
return str;
} catch (ParserConfigurationException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
