访问 Angular 2 应用程序的路由时如何在 URL 中保留查询字符串参数? [英] How to keep query string parameters in URL when accessing a route of an Angular 2 app?

问题描述

我有一个运行最新 alpha (37) 的 Angular 2 测试应用程序.只有三个路线，看起来像这样:

I have an Angular 2 test app running the latest alpha (37). There are just three routes, that look like this:

@RouteConfig([
  { path: '/', component: Home, as: 'home' },
  { path: '/errors', component: Errors, as: 'errors' },
  { path: '/about', component: About, as: 'about' }
])

我可以访问路由，当我在 URL 中放置查询字符串参数时，我可以很好地读取它们.但是，在我读取参数后不久，我注意到路由加载正常并且 URL 刷新，删除了查询字符串参数.

I can access the routes, and when I place query string params in the URL I can read them just fine. However, a few instants after I read the parameters, I noticed that the route loads fine and the URL refreshes, removing the query string parameters.

换句话说，访问这条路线:

In other words, accessing this route:

http://localhost:5555/errors?test=abc强>

加载 /errors 路由，但在应用程序加载后，URL 变为:

Loads the /errors route, but right after the application loads the URL turns into:

http://localhost:5555/errors

这会让用户感到困惑.我想在 URL 中保留查询字符串参数.

That would be confusing to a user. I would like to keep the query string parameters in the URL.

我知道，它是 alpha 版，但这是一个错误还是我忘记在路由器上设置一些东西?如何在 URL 中保留任何查询字符串参数?

I know, it's in alpha, but is this a bug or I forgot to set something up on the router? How can I keep whatever query string parameters in the URL?

谢谢！

推荐答案

此问题已在 Alpha 41 中修复.查询字符串现在已保留.

This is fixed in Alpha 41. The query string is now persisted.
