推荐答案

我并没有做任何特别的事情来启用此功能.我在第 https://appengine.google.com页面上显示了我的应用的角色 Owner /管理>权限.

I didn't do anything special to enable this functionality. I have role Owner for my app as displayed on page https://appengine.google.com/ Administration > Permissions.

如果我从自己的Google帐户注销，则该标头会消失.
如果我登录自己的Google帐户并访问网站上的安全区域，则会显示其他标题.

If I logout from my Google Account - this header dissapear.
Additional headers appear if I logged in into my Google Account and visit secured area on my site.

在 web.xml 中标记为这样的安全区域:

Secured area marked like this in web.xml:

<security-constraint>
    <web-resource-collection>
        <web-resource-name>Administration resources</web-resource-name>
        <url-pattern>/admin/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <role-name>admin</role-name>
    </auth-constraint>
</security-constraint>

在Firebug中看起来像这样:
