发送HTTP请求采用了apahe的HttpClient：
/** * HttpClient发送GET请求 * * @param host * @return */ public static String sendGetRequest(String host) { HttpClient httpClient = new HttpClient(); GetMethod getMethod = new GetMethod(host); getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, new DefaultHttpMethodRetryHandler()); String responseBody = null; try { int statusCode = httpClient.executeMethod(getMethod); if (statusCode != HttpStatus.SC_OK) { System.err.println(getMethod.getStatusLine()); } responseBody = getMethod.getResponseBodyAsString(); } catch (HttpException e) { System.out.println("请求出错!"); e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { getMethod.releaseConnection(); } return responseBody; }?
