HarmonyOS 鸿蒙Next 使用了navigation之后，如何在工具类中使用路由

单独封装一个module类就行了，在这个类里进行操作，参考demo:

import { RouterModel } from '../../model/RouterModel';
import { Logger } from '../util/Logger';
import { NavRouterName, RouterNameConstants } from './NavRouterBuilderName';

export class NavRouterModule {
  static builderMap: Map<string, WrappedBuilder<[object]>> = new Map<string, WrappedBuilder<[object]>>();
  static routerMap: Map<string, NavPathStack> = new Map<string, NavPathStack>();

  // Registering a builder by name.
  public static registerBuilder(builderName: string, builder: WrappedBuilder<[object]>): void {
    NavRouterModule.builderMap.set(builderName, builder);
  }

  // Get builder by name.
  public static getBuilder(builderName: string): WrappedBuilder<[object]> {
    const builder = NavRouterModule.builderMap.get(builderName);
    if (!builder) {
      Logger.info('not found builder ' + builderName);
    }
    return builder as WrappedBuilder<[object]>;
  }

  // Registering a router by name.
  public static createRouter(routerName: string, router: NavPathStack): void {
    NavRouterModule.routerMap.set(routerName, router);
  }

  // Get router by name.
  public static getRouter(routerName: string): NavPathStack {
    return NavRouterModule.routerMap.get(routerName) as NavPathStack;
  }

  // Jumping to a Specified Page by Obtaining the Page Stack.
  public static async push(router: RouterModel): Promise<void> {
    // Dynamically import the page to be redirected to.
    NavRouterModule.getRouter(router.routerName).pushPath({ name: router.builderName, param: router.param });
  }

  public static async replace(router: RouterModel): Promise<void> {
    NavRouterModule.getRouter(router.routerName).replacePath({ name: router.builderName, param: router.param})
  }

  // Obtain the page stack and pop it.
  public static pop(routerName: string, result?: object): void {
    // Find the corresponding route stack for pop.
    NavRouterModule.getRouter(routerName).pop(result);
  }

  // Get the page stack and clear it.
  public static clear(routerName: string): void {
    // Find the corresponding route stack for pop.
    NavRouterModule.getRouter(routerName).clear();
  }

  // Directly jump to the specified route.
  public static popToName(routerName: string, builderName: string): void {
    NavRouterModule.getRouter(routerName).popToName(builderName);
  }

  // Create routing information and put it into the routing stack table.
  public static navRouterPush(routerName: string, builderName: string, param?: object) {
    let router: RouterModel = new RouterModel();
    router.builderName = builderName;
    router.routerName = routerName;
    router.param = param;
    NavRouterModule.push(router);
  }

  public static navRouterReplace(routerName: string, builderName: string, param?: object) {
    let router: RouterModel = new RouterModel();
    router.builderName = builderName;
    router.routerName = routerName;
    router.param = param;
    NavRouterModule.replace(router);
  }

  public static mainNavRouterPush(builderName: string, param?: object) {
    NavRouterModule.navRouterPush(RouterNameConstants.NAV_SPLASH_ROUTER, builderName, param)
  }

  public static mainNavRouterReplace(builderName: string, param?: object) {
    NavRouterModule.navRouterReplace(RouterNameConstants.NAV_SPLASH_ROUTER, builderName, param)
  }

  public static mainNavRouterPop() {
    NavRouterModule.pop(RouterNameConstants.NAV_SPLASH_ROUTER)
  }
}

你这种跳转到登录页无非就是调用一下工具类的mainNavRouterPush方法罢了
