带有 resolve 方法参数的解析器

resolver with parameter on resolve method

所以我在 angular 5:

中实现了一个解析器
@Injectable()
export class AppResolver implements Resolve<MyComplexObject []> {
  constructor(private myService: MyService) {

   }
   resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<MyComplexObject[]> {
     return this.myService.getMyApi(myOption); // my option is a string
   }
}

现在 myOption 是硬编码字符串,我想更改它

在我的路由模块中我有:

resolve: {
  myResolver: AppResolver
}

我想也许我应该在这里指定 myOption 字符串的值,但是如何指定呢?

或者更好的是我实际调用解析器的地方

this.route.data.map(data => data.myResolver).subscribe(
  result => {
    // do something with the result (specify who the myOption is?? How)
  }
);

该参数不一定在浏览器中可见:

它将成为 url 的一部分:/.../.../myString/..

但它不是由参数引入的:url: /..&myParam=paramValue

所以我无法使用 myParam 从 url 中识别它并替换它

这里是发送 dataresolver,

的例子

路由配置:

{
  path: 'project/:id',
  component: ProjectComponent,
  resolve: { data: AppResolver },
  data: { resolvedata: 'myValue' }
}

解析器:

@Injectable()
export class AppResolver implements Resolve<MyComplexObject []> { 
  constructor(private myService: MyService, private router: Router) {} 
  resolve(route: ActivatedRouteSnapshot): Observable<MyComplexObject[]>|boolean { 
    let myParam = route.data['resolvedata']; 
    console.log(myParam); 
  } 
}
