通过httpclient模拟post请求，接收响应的时候报了这样一个警告：
org.apache.commons.httpclient.HttpMethodBase - Going to buffer response body of large or unknown size. Using getResponseBodyAsStream instead is recommended.
是由于返回的HTTP头没有指定contentLength，或者是contentLength大于上限（默认是1M）；
HttpClient建议使用getResponseBodyAsStream()代替getResponseBody()，可避免getResponseBody()可能带来的内存的耗尽问题。
代码如下：
public static String postByTextString(String url, String text, String token) { ???????HttpClient httpClient = new HttpClient(); ???????PostMethod postMethod = new PostMethod(url); ???????try { ???????????StringRequestEntity entity = new StringRequestEntity(text, "text/plain", Constants.CHARSET_UTF8); ???????????postMethod.setRequestEntity(entity); ???????????postMethod.setRequestHeader("token", token); ???????????httpClient.executeMethod(postMethod); ???????????if (postMethod.getStatusCode() == HttpStatus.SC_OK) {
// 通过读流的方式替代getResponseBodyAsString() ???????????????InputStream inputStream = postMethod.getResponseBodyAsStream(); ???????????????BufferedReader br = new BufferedReader(new InputStreamReader(inputStream)); ???????????????StringBuffer stringBuffer = new StringBuffer(); ???????????????String str; ???????????????while((str = br.readLine()) != null){ ???????????????????stringBuffer.append(str); ???????????????} ???????????????String response = new String(stringBuffer); ???????????????br.close(); // String response = new String(postMethod.getResponseBodyAsString()); ???????????????return response; ???????????} else { ???????????????return null; ???????????} ???????} catch (HttpException e) { ???????????e.printStackTrace(); ???????} catch (IOException e) { ???????????e.printStackTrace(); ???????} finally { ???????????postMethod.releaseConnection(); ???????} ???????return null;httpclient请求返回响应体，报警告"Going to buffer response body of large or unknown size"的解决方案
