Aurelia是否支持注入多個成員以進行陣列

Question

Aurelia（確切地說是aurelia-dependency-injection ）是否支持將多個成員注入到數組中（例如InversifyJS的multiject特性 ）？

例：

provider-common.ts：

class A { ... }

provider1.ts

let a1 = new A (...)
container.registerInstance(A, a1)

provider2.ts

let a2 = new A (...)
container.registerInstance(A, a2)

消費者

@inject(A)
class B {
  constructor (multipleAInstancesFromDiffirentProviders :Array<A>) {
      // I would expect multipleAInstancesFromDiffirentProviders to contain [a1,a2] (if such a feature is supported)
  }
}

Answer 1

您可以嘗試使用All.of(A) ：

    import {inject, All} from "aurelia-framework";

    @inject(All.of(A))
    class B {
        constructor (multipleAInstancesFromDiffirentProviders :Array<A>) {
        }
    }

Answer 2

最好是使用All.of(A) 。

您還可以使用以下替代方法：

import { Container } from 'aurelia-framework';

@inject(Container)
class B {
    constructor (container: Container) {
      var multipleAInstancesFromDifferentProviders : Array<A> = container.getAll(A);
    }
}
