重新解析查询参数更改后的数据? [英] re-resolving data upon query parameter change?

问题描述

在我的angular 2项目中，我无法通过导航到相同的URL但使用不同的查询参数来重新加载页面.我正在使用 resolve 来在加载页面时预提取数据.

In my angular 2 projects, I wasn't able to reload the page by navigating to the same URL but with different query params. I am using resolve to pre-fetch data upon loading the page.

我正在尝试让解析器在URL(查询参数)发生更改时重新获取数据.我该怎么办?

I am trying to get the resolver to re-fetch the data when there's URL (query param) change. How do I do this?

推荐答案

现在您可以在您的路由配置中使用它:

now you can with this in your route config:

{
  path: '',
  resolve: {
    data : DataResolver,
  },
  runGuardsAndResolvers: 'paramsOrQueryParamsChange',
  component: MainComponent
}

在路由配置中传递"paramsOrQueryParamsChange"将在每个参数或queryParams更改时触发DataResolver. 您可以像这样在MainComponent中获取解析器数据:

passing 'paramsOrQueryParamsChange' in your route config will trigger the DataResolver at each params or queryParams change.
you can get the resolvers data in your MainComponent like this:

ngOnInit() {
  this.activatedRoute.data.subscribe((resolversData) => {
     // is now triggered at each queryParams change
  })
}
