这可能是不是获取密码输入的最佳方式,因为它不会屏蔽输入。相反,请考虑使用带有密码输入字段的HTML表单。
This this probably isn't the best way to get password input, because it does not mask the input. Instead, consider using an HTML form with a password input field.
也许您正在寻找基本的HTTP身份验证?
Maybe you are looking for basic HTTP authentication instead?
您可以通过让您的Web服务器发送一些标题来设置它;例如使用PHP:
You can set this by getting your web server to send a few headers; for example with PHP:
<?php
if (!isset($_SERVER['PHP_AUTH_USER'])) {
header('WWW-Authenticate: Basic realm="My Realm"');
header('HTTP/1.0 401 Unauthorized');
echo 'Text to send if user hits Cancel button';
exit;
} else {
echo "<p>Hello {$_SERVER['PHP_AUTH_USER']}.</p>";
echo "<p>You entered {$_SERVER['PHP_AUTH_PW']} as your password.</p>";
}
?>
这将导致客户端显示如下对话框:
This will cause the client to show a dialog like this:
