所以，有人问我如何解决此问题，

so, someone was asking me how i solved this issue,

首先，我添加了一条新路线作为所有其他路线的后备路线，例如:

first i added a new route as a fallback to all other routes, something like this:

{path: ':url', loadChildren: './fallback/fallback.module#FallbackModule'}

然后在fallbackComponent内部，我们根据路由器导航结束事件上的url决定加载哪个模块.

then inside fallbackComponent we decide what module to load based on the url on router navigation end event.

在我的情况下，如果网址是/@ somestring，我想加载profileComponent并调用一些API

in my case, if the url was /@somestring, i wanted to load the profileComponent and call some APIs

  ngOnInit() {
    this.router.events.filter(event => event instanceof NavigationEnd)
      .subscribe((event) => {
        this.parseUrl(this.router.url);
      });
  }

  parseUrl(url: string) {
    let data = {};
    let parts: string[] = url.split('/');
    parts = parts.filter((item) => !!item);
    if (parts[0] && parts[0].indexOf('@') === 0) {
      data['component'] = 'profile';
      data['username'] = parts[0].replace('@', '');
    }
    this.viewData = data;
  }

并在模板中:

<template [ngIf]="viewData && viewData['component'] == 'profile'">
  <user-profile
    [title] = "viewData['view']"
    [username] = "viewData['username']"
  ></user-profile>
</template>

还值得一提的是，我们还必须重写DefaultUrlSerializer.serialize才能禁用对网址中特殊字符(@)的自动编码.

also worth to mention that we also had to override DefaultUrlSerializer.serialize to disable auto encoding for special characters (@) in urls.
