从 WebApi 提供分布式 Vue 组件

我需要能够从 asp.net 核心 WebApi 导入和呈现 vue 组件

我跟着这篇文章得到了一个想法，并想出了下面的代码。

端点确实被命中，并按我的预期返回了打包的组件字符串，但我在控制台中看到了这些错误：

拒绝从 'https://localhost:44385/api/DistributedComponent/Test' 执行脚本，因为其 MIME 类型 ('application/json') 不可执行，并且启用了严格的 MIME 类型检查。

和

vue.js:634 [Vue 警告]：无法解析异步组件：function () { return __awaiter(_this, void 0, void 0, function () { return __generator(this, function (_a) { switch ( a.label ) { case 0: return [4 / yield /, Object( js_util_external_component__WEBPACK_IMPORTED_MODULE_3 ["default"])('https://localhost:44385/api/DistributedComponent/Test')]; case 1: return [2 / return /, _a.sent()]; } }); }); 原因：TypeError：为promise检测到链接循环#

我怀疑我没有正确返回组件字符串，但我应该如何返回它？以及如何使用这些错误消息来帮助我了解我做错了什么？

外部组件.js

export default async function externalComponent(url) {
    const name = 'MyComponent';

    if (window[name]) return window[name];

    window[name] = new Promise((resolve, reject) => {
        const script = document.createElement('script');
        script.async = true;
        script.addEventListener('load', () => {
            resolve(window[name]);
        });
        script.addEventListener('error', () => {
            reject(new Error(`Error loading ${url}`));
        });
        script.src = url;
        document.head.appendChild(script);
    });

    return window[name];
}

控制器端点：

[HttpGet("Test")]
public string Test()
{
    // This is the output of the component after running
    // npx vue-cli-service build --target lib --formats umd-min --no-clean --dest server/components/MyComponent --name "MyComponent.[chunkhash]" server/components/MyComponent/MyComponent.vue

主要 Vue 组件：

<template>
    <MyComponent />
</template>

<script lang="ts">
    import { Vue, Component, Mixins } from "vue-property-decorator";

    import externalComponent from '../../js/util/external-component';
    const MyComponent = () => externalComponent('https://localhost:44385/api/DistributedComponent/Test');

    @Component({
        name: "Dashboard",
        components: {
            MyComponent
        }
    })
    export default class Dashboard extends Vue {
        constructor() {
            super();
        }
    }
</script>
