fsPromises.readlink(path[, options])

    读取 path 引用的符号链接的内容。 有关更多详细信息,请参阅 POSIX readlink(2) 文档。 成功时使用 linkString 解决 promise。

    Reads the contents of the symbolic link referred to by path. See the POSIX readlink(2) documentation for more detail. The promise is resolved with the linkString upon success.

    The optional options argument can be a string specifying an encoding, or an object with an encoding property specifying the character encoding to use for the link path returned. If the encoding is set to 'buffer', the link path returned will be passed as a <Buffer> object.
