Aurelia：在路由器的管道步骤中，如何将变量绑定到该路由器？ [英] Aurelia: During a Router's Pipeline Step, how do I bind a variable to that router?

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();
    }
}
