public void login() throws Exception{
		HttpClient httpclient = new DefaultHttpClient();
		Properties prop = System.getProperties();   
	    // HTTP代理的IP设置   
	    prop.setProperty("http.proxyHost", "proxy.zj.*******.com");   
	    // HTTP代理的端口设置   
	    prop.setProperty("http.proxyPort", "8080");   
	    //这里也可以设置不需要使用代理的地址   
	    prop.setProperty("http.nonProxyHosts", "localhost|10.70.*.*");   
		HttpHost proxy = new HttpHost("proxy.zj.********.com", 8080, "http");
		httpclient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,proxy);
		String url = "http://www.xiami.com/member/login";
		HttpPost post = new HttpPost(url);
		HttpClientParams.setCookiePolicy(httpclient.getParams(), CookiePolicy.BROWSER_COMPATIBILITY);
		List<NameValuePair> nvps = new ArrayList<NameValuePair>();

		HttpResponse response = httpclient.execute(post);
		post.abort();
		System.out.println("返回码	 ："+response.getStatusLine().getStatusCode());
		if(response.getStatusLine().getStatusCode()== 302){
