我试图从需要使用用户名/密码进行身份验证的网站下载xml文件。通过手动浏览当然没有问题，弹出窗口需要插入用户/密码，但在这里我希望它自动完成。这是我的代码HTTPS身份验证错误
Authenticator.setDefault(new Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication("[email protected]", "mypassword".toCharArray()); } });
try {
URL testURL=new URL("testingURL");
try {
FileUtils.copyURLToFile(testURL, dest);
} catch (IOException e) {
e.printStackTrace();
}
} catch (MalformedURLException e) {
e.printStackTrace();
}
，但是我得到的异常
