inputstream获取网页信息

一般来讲，网络通信是先获取网页信息，在进行信息解析，下面是2种一般形式获取望去网页信息的写放，注意（2）捕获异常（2）inputsream要close

一、private String readStream(InputStream is)
      {
         InputStreamReader isr;
         String result = "";
         try
         {
//          字节流转换为字符流
            isr = new InputStreamReader(is, "utf-8");
//          字符流一buffer的形式读取
            BufferedReader br = new BufferedReader(isr);
            String line = "";
            while((line = br.readLine()) != null)
            {
               result += line;
            }

         }
         catch(UnsupportedEncodingException e)
         {
            e.printStackTrace();
         }
         catch(IOException e)
         {
            e.printStackTrace();
         }
         return result;
      }
   }

}
