无法通过rest api更新webservice的远程数据库

Question

我有一个 bugzilla 服务器，我试图通过其余 api 访问它。我想通过REST远程更新数据库。 当我尝试运行我的代码时，出现以下异常：

W/DB      (  277): java.net.SocketException: Permission denied

RestClient.myputter 函数看起来像这样：

public static String myputter(String... params)
{
  String url = params[0];            
  String jsonBody = params[1]; 
  DefaultHttpClient client = new DefaultHttpClient();
   HttpPut putRequest = new HttpPut(url);
   try {
     StringEntity se = new StringEntity(jsonBody);
      se.setContentType("text/json");
      se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
      putRequest.setEntity(se);
      putRequest.addHeader("Content-Type", "application/json");
      putRequest.setEntity(se);
      putRequest.setHeader("Accept", "application/json");
      putRequest.setHeader("Content-Type", "application/json");

      HttpResponse response = client.execute(putRequest);
      int status_code=response.getStatusLine().getStatusCode();

client.execute 行抛出异常 有什么想法为什么会发生这种情况吗？
