[英] Angular 2 Routing Refresh
本文介绍了Angular 2 路由刷新的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在这里实施哈希定位策略，但它不起作用，请指导我.
这是我的 Angular &路由器版本

你们都知道在 angular 2 SPA 中，当我们刷新时，我们得到资源未找到或 404 错误，以避免我虽然实施了 hashlocationstrategy 但我没有成功
请分享您的想法并指导我.
谢谢大家.
解决方案
你只需要在app.routes.ts上更改
import { ModuleWithProviders } from '@angular/core';从'@angular/router' 导入 { Routes, RouterModule };从 './home/home.component' 导入 { HomeComponent };从 './users/user-list.component' 导入 { UserListComponent };从 './schedules/schedule-list.component' 导入 { ScheduleListComponent };从 './schedules/schedule-edit.component' 导入 { ScheduleEditComponent };const appRoutes: 路由 = [{ path: 'users', 组件: UserListComponent },{ path: 'schedules', 组件: ScheduleListComponent },{ path: 'schedules/:id/edit', 组件: ScheduleEditComponent },{ 路径:''，组件:HomeComponent }];导出常量路由: ModuleWithProviders = RouterModule.forRoot(appRoutes, {useHash: true });**用下面的代码替换上面的代码**从'@angular/core' 导入 { ModuleWithProviders };从'@angular/router' 导入 { Routes, RouterModule };从 './home/home.component' 导入 { HomeComponent };从 './users/user-list.component' 导入 { UserListComponent };从 './schedules/schedule-list.component' 导入 { ScheduleListComponent };从 './schedules/schedule-edit.component' 导入 { ScheduleEditComponent };const appRoutes: 路由 = [{ path: '', redirectTo: 'users', pathMatch: 'full' },{ path: 'users', 组件: UserListComponent },{ path: 'schedules', 组件: ScheduleListComponent },{ path: 'schedules/:id/edit', 组件: ScheduleEditComponent },];导出 const appRoutingProviders: any[] = [];export const routing = RouterModule.forRoot(appRoutes);
I am trying to Implement Hashlocation Strategy out here it is not working please guide me.

You all know in angular 2 SPA when we refresh we get resource not found or 404 error to avoid i though of implementing the hashlocationstrategy but i am not successfull
kindly share your thoughts and guide me guys.
Thanks for all.
解决方案
You only need to change on app.routes.ts
import { ModuleWithProviders } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { UserListComponent } from './users/user-list.component';
import { ScheduleListComponent } from './schedules/schedule-list.component';
import { ScheduleEditComponent } from './schedules/schedule-edit.component';
const appRoutes: Routes = [
{ path: 'users', component: UserListComponent },
{ path: 'schedules', component: ScheduleListComponent },
{ path: 'schedules/:id/edit', component: ScheduleEditComponent },
{ path: '', component: HomeComponent }
];
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes, {
useHash: true });
**Replace above code with below code**
import { ModuleWithProviders } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { UserListComponent } from './users/user-list.component';
import { ScheduleListComponent } from './schedules/schedule-list.component';
import { ScheduleEditComponent } from './schedules/schedule-edit.component';
const appRoutes: Routes = [
{ path: '', redirectTo: 'users', pathMatch: 'full' },
{ path: 'users', component: UserListComponent },
{ path: 'schedules', component: ScheduleListComponent },
{ path: 'schedules/:id/edit', component: ScheduleEditComponent },
];
export const appRoutingProviders: any[] = [
];
export const routing = RouterModule.forRoot(appRoutes);
