例如：

public static String sendGetResult(String url, int timeOut, String charset){BufferedReader br = null;InputStreamReader isr = null;InputStream is = null;HttpURLConnection huc = null;StringBuffer result = new StringBuffer("");URL newUrl = null;String line = null;try {newUrl = new URL(url);huc = (HttpURLConnection)newUrl.openConnection();huc.setRequestMethod("PUT");if (timeOut > 0) {huc.setConnectTimeout(timeOut);huc.setReadTimeout(timeOut);}int state = huc.getResponseCode();if ((state > 207) || (state < 200))return null;int state;is = huc.getInputStream();isr = charset != null ? new InputStreamReader(is, charset) : new InputStreamReader(is);br = new BufferedReader(isr);while ((line = br.readLine()) != null) {result.append("\r\n");result.append(line);}String str1 = result.toString().trim();return str1;}catch (IOException ioe){return null;} catch (OutOfMemoryError menorException) {System.out.println("發(fā)送PUT請求內(nèi)存溢出,內(nèi)存占用：" + result.capacity());System.out.println("本溢出請求地址：" + url);System.gc();return null;} catch (Exception e) {e.printStackTrace();System.out.println("發(fā)送Put請求異常！" + e.getMessage());return null;}finally {try {if (is != null) {is.close();}if (isr != null) {isr.close();}if (br != null) {br.close();}if (huc != null) {huc.disconnect()();}result = null;} catch (Exception e) {System.out.println("發(fā)送Put請求時(shí)關(guān)閉流和對象出錯(cuò)");}} }
