我想将在 AuthorizeStep 中找到的用户传递给 App类，然后转到主页模块。

I'd like to pass the user, found during the AuthorizeStep to either the App class and then to the home module.

这就是我所拥有的：

export class App { configureRouter(config, router) { config.addPipelineStep('authorize', AuthorizeStep); config.map([ {route: ['', ':filter'], name: "", moduleId: 'welcome'} {route: 'home', name: "home", moduleId: 'home' auth:true} ]); this.router = router; } } class AuthorizeStep { run(routingContext, next) { if (routingContext.nextInstructions.some(i => i.config.auth)) { this.client.get('auth/login') .then(response => { this.user = response.content; }); } return next(); } }

推荐答案

In我的应用程序我创建了一个名为AuthContext的类，其中包含currentUser属性。您可以将其注入AuthorizeStep的构造函数中，然后将其注入需要它的任何其他模型中。类似......

In my app I created a class called AuthContext with currentUser property. You can inject it in the constructor for the AuthorizeStep and then inject it in any other models that need it. Something like...

import {AuthContext} from './auth-context'; export class App { static inject() { return [AuthContext];} constructor(authcontext){ this.authContext = authcontext; } configureRouter(config, router) { config.addPipelineStep('authorize', AuthorizeStep); config.map([ {route: ['', ':filter'], name: "", moduleId: 'welcome'} {route: 'home', name: "home", moduleId: 'home' auth:true} ]); this.router = router; } } class AuthorizeStep { static inject() { return [AuthContext];} constructor(authcontext){ this.authContext = authcontext; } run(routingContext, next) { if (routingContext.nextInstructions.some(i => i.config.auth)) { this.client.get('auth/login') .then(response => { this.authcontext.user = response.content; }); } return next(); } }
