URL
ES 模块被解析并缓存为 URL。
这意味着包含 # 和 ? 等特殊字符的文件需要转义。
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 files containing
special characters such as # and ? need to be escaped.
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.
