如何将数据从 ASP.NET WebForms 传递到 Aurelia Global Scope [英] How to pass data from ASP.NET WebForms to Aurelia Global Scope
问题描述
我正在从基于 Web 表单的遗留应用程序引导 Aurelia.我的身份验证相关信息保存在自定义基页类中的 Web 表单应用程序中.
I am bootstrapping Aurelia from a Web-forms based legacy application. My authentication related information is maintained in the web-forms application in the Custom Base Page class.
我如何通过&将此身份验证信息维护到 Aurelia 的全局范围?这样我就可以在使用路由构建菜单时使用它来根据用户/角色显示/隐藏某些菜单项?
How do I pass & maintain this authentication information to Aurelia's global scope? So that I can use it while building the menus using routes to show/hide certain menu items based on the user/role?
推荐答案
您可以将逻辑置于您的自定义基页中，以将 <script> 标记添加到文档的头部，使所有javascript 应用程序可用的信息:
You could put logic your custom base page to add a <script> tag to the head of the document that makes all the information available to javascript applications:
<head>
...
<script>
window.appInfo = {
user: 'foo',
bar: 'baz'
};
</script>
</head>
<body aurelia-app="main">
...
然后在您的 aurelia 应用程序中，您可以根据需要访问此信息:
Then in your aurelia app you can access this info as needed:
export class App {
constructor() {
let info = window.appInfo;
// do something with the app info...
}
...
}
您甚至可以在容器中注册对象，使您能够将其声明为依赖项.这将使您的代码更具可移植性和可测试性.
You could even register the object in the container, enabling you to declare it as a dependency. This will make your code more portable and testable.
在 main.js 中:aurelia.container.registerInstance('app-info', window.appInfo);
In main.js: aurelia.container.registerInstance('app-info', window.appInfo);
@inject('app-info')
export class App {
constructor(info) {
// do something with the app info...
}
...
}
