file: URL

如果用于解析模块的 import 说明符具有不同的查询或片段，则会多次加载模块。

¥Modules are loaded multiple times if the import specifier used to resolve them has a different query or fragment.

import './foo.mjs?query=1'; // loads ./foo.mjs with query of "?query=1"
import './foo.mjs?query=2'; // loads ./foo.mjs with query of "?query=2" 拷贝

可以通过 /、//、或 file:/// 引用卷根。考虑到 URL 和路径解析的差异（比如百分比编码细节），建议导入路径时使用 url.pathToFileURL。

¥The volume root may be referenced via /, //, or file:///. Given the differences between URL and path resolution (such as percent encoding details), it is recommended to use url.pathToFileURL when importing a path.
