Question

我没有设法从android模拟器查询Web服务（之前我有一个UnresolvedHostException，但这没关系）。现在我可以继续了，我在HttpResponse的实体中没有返回任何内容（长度为-1）。

String url = serverUrl + resource;
Log.d(TAG, "GET: " + url);
HttpClient client = new DefaultHttpClient();
HttpGet getMethod = new HttpGet((url));
getMethod.setHeader("User-Agent", USER_AGENT);
getMethod.addHeader("Authorization", "Basic " + getCredentials());   
HttpResponse httpResponse = client.execute(getMethod);
Log.e(TAG, "RESPONSE:" + httpResponse);
Log.i(TAG,httpResponse.getStatusLine().toString());
Log.i(TAG + "1",httpResponse.getLocale().toString());
Log.i(TAG + "2",httpResponse.getHeaders(USER_AGENT).toString());
Log.i(TAG + "3",httpResponse.getEntity().toString());
Log.i(TAG + "4",httpResponse.getEntity().getContent().toString()); 
int length = (int) httpResponse.getEntity().getContentLength();
Log.e(TAG + "5", "LENGTH:" + length);

日志：

我不在代理后面，并在清单中添加了INTERNET权限。不检索获取查询（http://www.google.com/search?q=android）内容的原因可能是什么。非常感谢你的帮助， LUC

不要依赖内容长度。有时它无法找到内容长度只需检索返回的数据

URL url = new URL("xyz.com";); 
URLConnection conn = url.openConnection();
conn.setRequestProperty("Authorization", "Basic"+getcredentials());
BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
//read d response till d end
while ((line = rd.readLine()) != null) {//process the line response}

无法获取httpResponse内容
