Angular 传递将数据解析为子路由

Question

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

所以我的路线是这样的:

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，我从服务中解析了我的项目数据，并可以通过以下方式在 ProjectDetailComponent 中访问它们

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它的所有子路由组件？

我现在可以执行以下操作来解析子组件中的项目数据:

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}}
    ]
  }
]

但这看起来很丑陋而且是错误的。

Answer 1

这里有两个选择:

1.您可以通过子解析器访问父解析数据，方法是创建特定于子的解析器并访问路由的父属性。

[...模块.ts | ...组件.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，并从子组件中访问父数据。

[...模块.ts | ...组件.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;
        });
}
