Aurelia：在路由器的管道步骤中，如何将变量绑定到该路由器？

问题描述

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();
    }
}
