Question

我编写的代码可以登录并获取特定网站的HTML。

        String loginQuery = Sites.LOGIN_QUERY + "&member_no=" + id + "&password=" + pw;
        HttpsURLConnection con;

        con = (HttpsURLConnection) new URL(Sites.LOGIN_URL).openConnection();

        con.setRequestMethod("POST");
        con.setRequestProperty("Content-length", String.valueOf(loginQuery.length()));
        con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        con.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0;Windows98;DigExt)");
        con.setDoOutput(true);
        con.setDoInput(true);

        // Exception in this line...
        DataOutputStream output = new DataOutputStream(con.getOutputStream());

        output.writeBytes(loginQuery);
        output.close();

问题是上面的代码运行良好但是在更新到android 5.0之后，发生了javax.net.ssl.SSLHandshakeException。我的设备以前的操作系统版本是4.4。

我在更新操作系统的过程中没有改变任何代码。我该如何解决这个问题？
