如何放置浏览器'；在JSP中创建本机登录提示符，并检索用户名&；密码

我希望web浏览器使用默认的登录提示（如下所示）请求用户名和密码。

---

我读过关于如何实现它的文章，但它是针对ASP的。我希望它在JSP或servlet中完成，我还想知道如何在我的servlet中接收这些用户名和密码

您需要使用

BASIC

身份验证。同样，您需要使用

JAAS

。 提供基于

表单的身份验证。但是，当您需要
基本
身份验证时，您需要

<login-config>
     <auth-method>BASIC</auth-method>
</login-config>

为此，您必须使用基本身份验证。您可以参考以下链接，它使用servlet提供基本身份验证

<login-config>
        <auth-method>BASIC</auth-method>
</login-config>



希望对您有所帮助。
谢谢。这很有帮助
