本文介绍了一种将Java中的InputStream转换为String的有效方法。通过使用BufferedReader读取输入流，并逐行构建StringBuilder，最终将其转换为字符串。文章还展示了如何处理可能发生的IOException异常，并确保输入流在完成后被正确关闭。

   public String convertStreamToString(InputStream is) {
      /*
       * To convert the InputStream to String we use the
       * BufferedReader.readLine() method. We iterate until the BufferedReader
       * return null which means there's no more data to read. Each line will
       * appended to a StringBuilder and returned as String.
       */
      BufferedReader reader = new BufferedReader(new InputStreamReader(is));
      StringBuilder sb = new StringBuilder();

      String line = null;
      try {
         while ((line = reader.readLine()) != null) {
            sb.append(line); // + "/n");
         }
      } catch (IOException e) {
         e.printStackTrace();
      } finally {
         try {
            is.close();
         } catch (IOException e) {
            e.printStackTrace();
         }
      }

      return sb.toString();
   }
