httpclient解析gzip网页

转自http://www.cnblogs.com/yesun/archive/2008/10/31/1323432.html
请求时加上：getHC.setRequestHeader("Accept-Encoding","gzip, deflate");
解析时

String acceptEncoding = "";
     if(getHC.getResponseHeader("Content-Encoding")!=null)
      acceptEncoding = getHC.getResponseHeader("Content-Encoding").getValue();
     StringBuffer sb =new StringBuffer();
     log.debug("acceptEncoding:"+acceptEncoding);
     if(acceptEncoding.toLowerCase().indexOf("gzip") > -1)
     {
      //建立gzip解压工作流
      InputStream is = getHC.getResponseBodyAsStream();
      GZIPInputStream gzin = new GZIPInputStream(is);
      InputStreamReader isr = new InputStreamReader(gzin, charset); // 设置读取流的编码格式，自定义编码
      java.io.BufferedReader br = new java.io.BufferedReader(isr);
      String tempbf;
      while((tempbf=br.readLine())!=null){
       sb.append(tempbf);
       sb.append("\r\n");
      }
      isr.close();
      gzin.close();
     }
     else
     {
      InputStreamReader isr = new InputStreamReader(getHC.getResponseBodyAsStream(), charset); // 设置读取流的编码格式，自定义编码
      java.io.BufferedReader br = new java.io.BufferedReader(isr);
      String tempbf;
      while((tempbf=br.readLine())!=null){
       sb.append(tempbf);
       sb.append("\r\n");
      }
      isr.close();
     }
     getHC.abort();
     getHC.releaseConnection();
     ((SimpleHttpConnectionManager)httpClient.getHttpConnectionManager()).shutdown();
