SAP Spartacus navigation入口：
/** * Sets up the location change listener and performs the initial navigation. */ initialNavigation() { this.setUpLocationChangeListener(); if (this.navigationId === 0) { this.navigateByUrl(this.location.path(true), { replaceUrl: true }); } } /** * Navigates to a view using an absolute route path. * * @param url An absolute path for a defined route. The function does not apply any delta to the * current URL. * @param extras An object containing properties that modify the navigation strategy. * The function ignores any properties in the `NavigationExtras` that would change the * provided URL. * * @returns A Promise that resolves to 'true' when navigation succeeds, * to 'false' when navigation fails, or is rejected on error. * * @usageNotes * * The following calls request navigation to an absolute path. * * ``` * router.navigateByUrl("/team/33/user/11"); * * // Navigate without updating the URL * router.navigateByUrl("/team/33/user/11", { skipLocationChange: true }); * ``` * * @see [Routing and Navigation guide](guide/router) * */ navigateByUrl(url, extras = { skipLocationChange: false }) { if (isDevMode() && this.isNgZoneEnabled && !NgZone.isInAngularZone()) { this.console.warn(`Navigation triggered outside Angular zone, did you forget to call 'ngZone.run()'?`); } const urlTree = isUrlTree(url) ? url : this.parseUrl(url); const mergedTree = this.urlHandlingStrategy.merge(urlTree, this.rawUrlTree); return this.scheduleNavigation(mergedTree, 'imperative', null, extras); }
RouterStateSnapshot的url字段里包含的electronics-spa/en/USD是怎么来的？
ActivatedRouteSnapshot
array是一个闭包：
此时还没有从后台请求数据，前台怎么知道url应该为electronics-spa/en/USD？
