Javascript 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

我遵循这一思路，想出了下面的代码

端点确实被命中，并像我预期的那样返回打包组件字符串，但我在控制台中看到以下错误：

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

及

vue.js:634[vue warn]：解析异步组件失败：函数（）{return\uu waiter（_this，void 0，void 0，函数（）{return\uu生成器（this，函数（_a））{ 开关（a.标签）{ 案例0:return[4/yield/，Object（js_util_external_component_网页_IMPORTED_MODULE_3[“default”]）（'https://localhost:44385/api/DistributedComponent/Test')]; 案例1:return[2/return/，_a.sent（）]； } }); }); } 原因：TypeError:检测到promise的链接周期#

我怀疑我没有正确返回组件字符串，但是我应该如何返回它呢？我如何使用这些错误信息来帮助我理解我做错了什么

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：

}

<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>

从“Vue属性装饰器”导入{Vue，Component，Mixins}；
从“..//js/util/externalComponent”导入外部组件；
常量MyComponent=（）=>externalComponent（'https://localhost:44385/api/DistributedComponent/Test');
@组成部分({
名称：“仪表板”，
组成部分：{
真菌成分
}
})
导出默认类仪表板扩展Vue{
构造函数（）{
超级（）；
}
}

我通过将控制器端点更新为：

[HttpGet("Test")]
public async Task<IActionResult> Test()
{
    var bytes = await System.IO.File.ReadAllBytesAsync(@"Path\To\MyComponent.c9b7fae39bb9d71ad3e7.umd.min.js");

    return File(bytes, "application/javascript", "MyComponent.umd.min.js");
}

这消除了异步组件错误（在返回

window[name]

我现在确实得到了一份工作

TypeError:无法读取未定义的

我为它打开了门
