URL
ES 模块被解析并缓存为 URL。
这意味着特殊字符必须是百分比编码的,比如使用 %23 的 #、使用 %3F 的 ?。
支持 file:、node: 和 data: URL 协议。
除非使用自定义的 HTTPS 加载器,否则 Node.js 本身不支持像 'https://example.com/app.js' 这样的说明符
ES modules are resolved and cached as URLs. This means that special characters
must be percent-encoded, such as # with %23 and ? with %3F.
file:, node:, and data: URL schemes are supported. A specifier like
'https://example.com/app.js' is not supported natively in Node.js unless using
a custom HTTPS loader.
