当前行为：

Ionic 3.5.0 奇怪的 URL 行为
我的应用程序有基本的界面！ 一个 LoginPage、SignupPage...登录或注册后它会进入选项卡界面..我想没什么特别的！
首先，“nav/n4”是默认行为吗？
http://localhost :8100/#/nav/n4/login
http://localhost :8100/#/nav/n4/app/tabs/t0/perfil/perfil

我用 ionic g 创建了页面和标签
对于所有页面，我都为它们设置了段，例如，名称如下：
@IonicPage({ 段：'perfil' })

预期行为：

http://localhost :8100/#/login
http://localhost :8100/#/app/perfil
