httpclient不适用于真实的设备

Question

我使用此代码对我的Web服务器执行HttpGet请求。它在模拟器上工作很好，但不是在我的HTC Sense中。Excecution刚刚结束而不进行任何HTTP请求。任何想法？

File f = new File(user.getPhotopath());
List<NameValuePair> reqparams = new LinkedList<NameValuePair>();
reqparams.add(new BasicNameValuePair("email", user.getEmail()));
reqparams.add(new BasicNameValuePair("pwd", user.getPassword()));
reqparams.add(new BasicNameValuePair("name", user.getScreenName()));
reqparams.add(new BasicNameValuePair("photo", f.getName()));
reqparams.add(new BasicNameValuePair("preference", user.getPrefs()));
reqparams.add(new BasicNameValuePair("bluetoothid", bid));

String urlstring = "http://www.mysite.com/me?"+ URLEncodedUtils.format(reqparams, "utf-8");

try {
    URL url = new URL(urlstring);

URI myURI = null;
try {
    myURI = url.toURI();
} catch (URISyntaxException e) {
                e.printStackTrace();
}
HttpClient httpClient = new DefaultHttpClient();
HttpGet getMethod = new HttpGet(myURI);
HttpResponse webServerResponse = null;
HttpEntity httpEntity = null;
try {
    webServerResponse = httpClient.execute(getMethod);
    httpEntity = webServerResponse.getEntity();
} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
if (httpEntity != null) {

    InputStream instream = httpEntity.getContent();
    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 {
            resultStr = sb.toString();
            instream.close();
        } catch (IOException e) {
                e.printStackTrace();
        }
    }

Answer 1

虽然您的方法是正确的并且将工作，但更容易使用 entityutils 辅助类别将响应体作为字符串检索。简单：

String body = EntityUtils.toString(httpEntity);

Answer 2

There was no exception nor warning in stacktrace. Only memory allocation messages. Anyway i solved it by using URLConnection instead of HttpClient :

try {
      URL url = new URL(urlstring);
      URLConnection connection = url.openConnection();
      InputStream inputStream = connection.getInputStream();
      BufferedInputStream bufferedInput = new BufferedInputStream(inputStream);

    // Read the response into a byte array
      ByteArrayBuffer byteArray = new ByteArrayBuffer(50);
      int current = 0;
      while((current = bufferedInput.read()) != -1){
            byteArray.append((byte)current);
      }

      // Construct a String object from the byte array containing the response
     resultStr = new String(byteArray.toByteArray());
    } catch (Exception e) {
      e.printStackTrace();
    }

For some reason it worked. Still trying to figure what went wrong.
