Angular pass 将数据解析为子路由

问题描述：

我有以下组件结构

项目

编辑项目
子资源1
子资源2
子资源3

所以我的路由看起来像这样:

So my routing looks like this:

const childroutes = [
  {
    path: '',
    children: [
      { path: 'edit', component: EditProjectComponent},
      { path: 'subres1', component: Subres1Component},
      { path: 'subres2', component: Subres2Component},
      { path: 'subres3', component: Subres3Component},
      { path: 'subres4', component: Subres4Component}
    ]
  }
]

{
    path: 'project/:projectId', 
    component: ProjectDetailComponent,
    children: childroutes,
    resolve: { project: ProjectResolver} /** resolve Project from ProjectService **/
}

如您所见，我从服务解析了我的 Projectdata，并且可以通过

As you can see i resolve my Projectdata from a service and can access them in ProjectDetailComponent via

this.route.snapshot.data

那么现在的问题是，如何将EditProjectComponent"中解析的数据传递给其所有子路由组件?

So now the question is, how can i pass the data resolved in "EditProjectComponent" to all its childroutes components?

我现在可以执行以下操作来解析子组件中的项目数据:

I now that i could do the following to resolve project-data in childcomponents:

const childroutes = [
  {
    path: '',
    children: [
      { path: 'edit', component: EditProjectComponent,resolve: { project: ProjectResolver}},
      { path: 'subres1', component: Subres1Component,resolve: { project: ProjectResolver}},
      { path: 'subres2', component: Subres2Component,resolve: { project: ProjectResolver}},
      { path: 'subres3', component: Subres3Component,resolve: { project: ProjectResolver}},
      { path: 'subres4', component: Subres4Component,resolve: { project: ProjectResolver}}
    ]
  }
]

但这看起来既丑陋又错误.

But this seems ugly and wrong.

答

这里有两个选择:

1.您可以通过创建子特定解析器并访问路由的父属性，通过子解析器访问父解析数据.

1. You can access parent resolve data via the child's resolver by creating a child-specific resolver and accessing the route's parent property.

[...module.ts |...component.ts]

{
    path: 'project/:projectId', 
    component: ProjectDetailComponent,
    resolve: { project: ProjectResolver }
    children: [
        { 
            path: ':projectId/edit',
            component: EditProjectComponent,
            resolve: { edit: EditProjectResolve }
        }
    ]
}

edit-project-component.ts

ngOnInit() {
    this.edit = this.route.snapshot.data.edit;
}

2. 您可以一起绕过子组件的解析器并从子组件内部访问父数据.

2. You can bypass the child's resolver all together and access parent data from within the child component.

[...module.ts |...component.ts]

{
    path: 'project/:projectId', 
    component: ProjectDetailComponent,
    resolve: { project: ProjectResolver }
    children: [
        { 
            path: ':projectId/edit',
            component: EditProjectComponent
        }
    ]
}

edit-project-component.ts

ngOnInit() {
    this.route.parent.data
        .subscribe((data) => {
            this.edit = data.edit;
        });
}
