从 Angular 5.2 开始，您可以进行路由器配置以将所有参数继承到子状态.如果对血腥细节感兴趣，请参阅此提交，但它是如何为我工作的:

As of Angular 5.2, you can do Router configuration to inherit all params to child states. See this commit if interested in the gory details, but here's how it's working for me:

无论您在何处调用 RouterModule.forRoot()，都包含一个配置对象，其继承策略设置为 always(默认为 emptyOnly>):

Wherever you have your call to RouterModule.forRoot(), include a configuration object with the inheritance strategy set to always (default is emptyOnly):

import {RouterModule, ExtraOptions} from "@angular/router";

export const routingConfiguration: ExtraOptions = {
  paramsInheritanceStrategy: 'always'
};

export const Routing = RouterModule.forRoot(routes, routingConfiguration);

现在，当您在子组件中查看 ActivatedRoute 时，祖先的参数会出现在那里(例如 activatedRoute.params)，而不是像 这样混乱的东西activateRoute.parent.parent.parent.params.您可以直接访问该值(例如 activatedRoute.params.value.userId)或通过 activatedRoute.params.subscribe(...) 订阅.

Now when you're in a child component looking at a ActivatedRoute, ancestors' params appear there (e.g. activatedRoute.params) rather than something messy like activatedRoute.parent.parent.parent.params. You could access the value directly (e.g. activatedRoute.params.value.userId) or subscribe via activatedRoute.params.subscribe(...).
