URL提交表单问题~~~~~~

Question

本来是使用httpclient来get、post数据的，但是由于网站改为https，是通过加密的，本来吧是很会httpclient，但是又加入了ssl认证，所以改为java.net.URL来get/post，但是我怎么试都登陆不了:如下是我的代码        URLConnection post = (new URL("https://***********/login.aspx")).openConnection();
        
        HttpsURLConnection huc = (HttpsURLConnection) post;
        
        huc.setDoOutput(true);
        huc.setRequestMethod("POST");
        post.setRequestProperty("Content-type","text/html");  
        post.setRequestProperty("Cookie", cookie);
        post.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)");

        PrintWriter out = new PrintWriter(huc.getOutputStream());
        out.print("lang=ch");
        out.print("&username=********");
        out.print("&password=********");   
        BufferedReader br = new BufferedReader(new InputStreamReader(huc.getInputStream()));
        
        huc.connect();         String line = br.readLine();         while(line != null){ 
        System.out.println(line); 
        line = br.readLine();         }
