anchor.diff:        These are the same lines that we removed in the previous [Routing](toh-pt5.html) chapter.
         We didn't know at the time that we'd need the *HeroDetailComponent* again. So we tidied up.

         我们不知道现在会再次需要*`HeroDetailComponent`*类，所以把它们清理掉了。
   
         Now we *must* put these lines back. If we don't, Angular will ignore the `<my-hero-detail>`
  
positive.code:   
    We'll complete `HeroService` by creating `post`, `put` and `delete` methods to meet our new requirements.
  
    我们将为`HeroService`添加`post`、`put`和`delete`的http调用来彻底满足我们的需求。

      We already have `HeroDetailComponent` for viewing details about a specific hero. 
      Add and Edit are natural extensions of the detail view, so we are able to reuse `HeroDetailComponent` with a few tweaks.
