Socket http请求中文乱码问题

各位高手,麻烦帮忙看看这个 http请求乱码问题,百思不得其解啊....

Socket http请求"http://www.gome.com.cn/ec/homeus/browse/provinceDroplet.jsp?callback=g"时返回乱码,网页是utf-8,编码的

代码如下:

OutputStream os = null;

BufferedReader br = null;

Socket s = null;

try {

StringBuffer req = new StringBuffer();

req.append("GET /ec/homeus/browse/provinceDroplet.jsp?callback=g HTTP/1.1\r\n");

req.append("Accept: text/javascript, application/javascript, */*\r\n");

req.append("Accept-Language: zh-cn\r\n");

req.append("User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET4.0C; .NET4.0E)\r\n");

req.append("Host: www.gome.com.cn\r\n");

req.append("Connection: Close\r\n");

req.append("\r\n");

s = new Socket("www.gome.com.cn",80);

os = s.getOutputStream();

br = new BufferedReader(new InputStreamReader(s.getInputStream(),"utf-8"));

os.write(req.toString().getBytes());

os.flush();

String tmp = "";

StringBuffer sbRespon = new StringBuffer();

while((tmp = br.readLine())!=null){

sbRespon.append(tmp + "\r\n");

}

System.out.println(sbRespon.toString());

} catch (IOException e) {

try {

if (br != null) br.close();

if (os != null) os.close();

if (s != null) s.close();

} catch (IOException e2) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

------解决方案--------------------

Web服务器都是有压缩的，而且大多数服务器就算你不指定压缩算法，它也不会发送未压缩的原文，你这个服务器也不例外，它默认采用GZIP压缩算法，在它返回的Header里写得很清楚了，Content-Encoding: gzip，所以你需要用GZIPInputStream来解压缩。下面代码我试了一下没问题。
