Socket http请求中文乱码问题

[goddy2014]

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();
}
}

InputStreamReader里的utf-8缓存gbk、gb2312或者不输入试试。

换其他编码的也不行

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。 屏幕输出： HTTP/1.1 200 OK Server: Tengine Date: Tue, 10 Jun 2014 06:35:56 GMT Content-Type: text/html; charset=UTF-8 Transfer-Encoding: chunked Connection: close Content-Encoding: gzip X-ATG-Version: version=QVRHUGxhdGZvcm0vMTAuMC4zcDM= Content-Language: zh-CN X-Powered-By: Servlet/2.5 JSP/2.1 X-Cache: HIT from proxy Set-Cookie: BIGipServerpool_ATG_nginx=3591780874.20480.0000; path=/ p3p: CP="NON DSP COR CURa ADMa DEVa TAIa PSAa PSDa IVAa IVDa CONa HISa TELa OTPa OUR UNRa IND UNI COM NAV INT DEM CNT PRE LOC" g({"citys":[{"city":"北京","id":"11000000"},{"city":"天津","id":"12000000"},{"city":"河北省","id":"13000000"},{"city":"山西省","id":"14000000"},{"city":"内蒙古","id":"15000000"},{"city":"上海","id":"21000000"},{"city":"浙江省","id":"22000000"},{"city":"江苏省","id":"23000000"},{"city":"安徽省","id":"24000000"},{"city":"福建省","id":"25000000"},{"city":"山东省","id":"26000000"},{"city":"广东省","id":"31000000"},{"city":"广西","id":"32000000"},{"city":"海南省","id":"33000000"},{"city":"湖北省","id":"41000000"},{"city":"湖南省","id":"42000000"},{"city":"河南省","id":"43000000"},{"city":"江西省","id":"44000000"},{"city":"黑龙江省","id":"51000000"},{"city":"吉林省","id":"52000000"},{"city":"辽宁省","id":"53000000"},{"city":"宁夏","id":"61000000"},{"city":"新疆","id":"62000000"},{"city":"青海省","id":"63000000"},{"city":"陕西省","id":"64000000"},{"city":"甘肃省","id":"65000000"},{"city":"四川省","id":"71000000"},{"city":"云南省","id":"72000000"},{"city":"贵州省","id":"73000000"},{"city":"重庆市","id":"74000000"},{"city":"西藏","id":"75000000"},{"city":"台湾省","id":"81000000"},{"city":"香港","id":"82000000"},{"city":"澳门","id":"83000000"},{"city":"钓鱼岛","id":"84000000"}]})

话说为什么不直接用HttpClient或者下面这样用HttpURLConnection，直接用Socket很麻烦的。。

	public static void main(String[] args) throws IOException {
		URL url = new URL("http://www.gome.com.cn/ec/homeus/browse/provinceDroplet.jsp?callback=g");
		HttpURLConnection connection = (HttpURLConnection)url.openConnection();
		
		connection.connect();
		InputStream in = connection.getInputStream();
		
		GZIPInputStream gzip = new GZIPInputStream(in);
		ByteArrayOutputStream baos = new ByteArrayOutputStream();
		
		byte[] buf = new byte[1024];
		int n;
		while ((n = gzip.read(buf)) != -1) {
			baos.write(buf, 0, n);
		}
		
		String content = new String(baos.toByteArray(), "UTF-8");
		System.out.println(content);
		
		connection.disconnect();
	}
