Going to buffer response body of large or unknown size.Using getResponseBodyAsStream instead is recommened

原始写法

byte[] responseBody=postMethod.getResponseBody()
String result=new String("","UTF-8");

　　更换为

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 result=stringBuffer.toString();
