我正在开发一个Android应用程序，我在其中点击了一个URL并以HTML格式获取响应。当我尝试从InputStream接收数据时抛出异常。我发布我的代码和日志。请检查并帮我解决此异常。
//paramString1 = url,paramString = header, paramList = paramiters
public String a(String paramString1 , String paramString2, List paramList)
{
String str1 = null;
DefaultHttpClient localDefaultHttpClient = new DefaultHttpClient();
localDefaultHttpClient.getParams().setParameter("http.useragent", "Mozilla/5.0 (Windows NT 6.1; rv:12.0) Gecko/20120403211507 Firefox/12.0");
HttpParams localHttpParams = localDefaultHttpClient.getParams();
HttpConnectionParams.setConnectionTimeout(localHttpParams, 20000);
HttpConnectionParams.setSoTimeout(localHttpParams, 30000);
HttpPost localHttpPost = new HttpPost(paramString1);
localHttpPost.addHeader("Accept-Encoding", "gzip");
InputStream localInputStream = null;
try {
localHttpPost.setEntity(new UrlEncodedFormEntity(paramList));
localHttpPost.setHeader("Referer", paramString2);
HttpResponse localHttpResponse = localDefaultHttpClient.execute(localHttpPost);
int i = localHttpResponse.getStatusLine().getStatusCode();
Log.d(getClass().getSimpleName(), " response code " + i);
localInputStream = localHttpResponse.getEntity().getContent();
Header localHeader = localHttpResponse.getFirstHeader("Content-Encoding");
if ((localHeader != null) && (localHeader.getValue().equalsIgnoreCase("gzip"))) {
GZIPInputStream localObject = null;
localObject = new GZIPInputStream(localInputStream);
Log.d("API", "GZIP Response decoded!");
BufferedReader localBufferedReader = new BufferedReader(new InputStreamReader((InputStream)localObject, "UTF-8"));
StringBuilder localStringBuilder = new StringBuilder();
while (true) {
String str2 = localBufferedReader.readLine();
if (str2 == null)
break;
localHttpResponse.getEntity().consumeContent();
str1 = localStringBuilder.toString();
localStringBuilder.append(str2).append("\n");
}
}
}
catch (IOException localIOException) {
localHttpPost.abort();
Log.w(getClass().getSimpleName(), "Error IOException for URL " + paramString1, localIOException);
}
catch (Exception localException) {
localHttpPost.abort();
Log.w(getClass().getSimpleName(), "Error Exception for URL " + paramString1, localException);
}
return (String)str1;
}
