Angular 6-带前缀的动态路由 [英] Angular 6 - Dynamic Routing with Prefix

问题描述

我正在开发Angular通用应用程序.我想创建带有自定义前缀的动态路由，但是找不到与我的案例有关的任何有用的文档.任何帮助将不胜感激...

I am working on an Angular Universal Application. I want to create dynamic routes with custom prefix but I am unable find any helpful documentation related with my case. Any Help will be appreciated...

详细信息:

我所拥有的是4个页面，其中包含4个不同的动态URL:

What I have is, I have 4 pages with 4 different dynamic URLs which are:

• 主页(http://example.com/)
• 类别页面(http://example.com/{category_name})
• 子类别页面(http://example.com/{category_name}/{sub_category_name})
• 产品页面(http://example.com/p{product_id}-{product_name})
• 用户页面(http://example.com/user{user_id}-{user_name})

• Home Page (http://example.com/)
• Category Page (http://example.com/{category_name})
• Sub Category Page (http://example.com/{category_name}/{sub_category_name})
• Product Page (http://example.com/p{product_id}-{product_name})
• User Page (http://example.com/user{user_id}-{user_name})

我做什么

我已经注册了一条处理主页"，类别"和子类别"页面的路由，因为它们具有相同的UI，且具有以下所述的动态类别级别，

I have registered a single route to handle Home, Category and Sub Category Pages because they have same UI with dynamic category levels mentioned below,

RouterModule.forRoot([
      {path: '**', component: HomeComponent, data: {title: 'Home', description: 'Homepage - quick overview.'}}
    ])

苦苦挣扎:

现在，我无法添加产品页面和用户页面的路由，我无法理解，如何分别在产品页面和用户页面中的斜线之后和ids之前添加p和user前缀.没有这些前缀，路由工作正常.

Now, I am unable to add the routes for Product and User Page, I am unable to understand, how to add p and user prefixs after slash and before ids in Product and User Pages respectively. Without these prefixs, routing is working fine.

产品&必填URL的示例用户页面

• 产品页面( http://example.com/p123-Product-Name )
• 用户页面(http://example.com/user123-用户名)

• Product Page (http://example.com/p123-Product-Name)
• User Page (http://example.com/user123-User-Name)

我正在使用@angular/router进行路由.

谢谢.

推荐答案

感谢@Yuriy重新打开它，我已经从@IngoBürk的评论中得到了答案. 下面提到的 Gist 帮助我通过正则表达式创建了路由. https://gist.github.com/matanshukry/22fae5dba9c307baf0f364a9c9f7c115

Thanks, @Yuriy to reopen this, I have already got the answer from @Ingo Bürk's comment. The below mentioned Gist helped me to create routes through the regex. https://gist.github.com/matanshukry/22fae5dba9c307baf0f364a9c9f7c115

作为参考，我在下面添加了源代码，

For reference, I have added the source below,

/**
 * Copyright (c) Matan Shukry
 * All rights reserved.
 */

import { UrlSegment, UrlSegmentGroup, Route } from '@angular/router';

// export type UrlMatchResult = {
    // consumed: UrlSegment[]; posParams?: { [name: string]: UrlSegment };
// };

export function ComplexUrlMatcher(paramName: string, regex: RegExp) {
    return (
        segments: UrlSegment[],
        segmentGroup: UrlSegmentGroup,
        route: Route) => {

        const parts = [regex];
        const posParams: { [key: string]: UrlSegment } = {};
        const consumed: UrlSegment[] = [];

        let currentIndex = 0;

        for (let i = 0; i < parts.length; ++i) {
            if (currentIndex >= segments.length) {
                return null;
            }
            const current = segments[currentIndex];

            const part = parts[i];
            if (!part.test(current.path)) {
                return null;
            }

            posParams[paramName] = current;
            consumed.push(current);
            currentIndex++;
        }

        if (route.pathMatch === 'full' &&
            (segmentGroup.hasChildren() || currentIndex < segments.length)) {
            return null;
        }

        return { consumed, posParams };
    }
}

使用方法

/**

 */

export const UserRoutes: Routes = [
  {
    path: 'users',
    component: UserComponent,
    children: [
      {
        path: '',
        component: UserListComponent
      },
      {
        matcher: ComplexUrlMatcher("id", /[0-9]+/),
        component: UserItemComponent
      },
    ]
  }
];

@NgModule({
  imports: [RouterModule.forChild(UserRoutes)],
  exports: [RouterModule]
})
export class UserRoutingModule { }
