fs.readdirSync(path[, options])


    读取目录的内容。

    Reads the contents of the directory.

    See the POSIX readdir(3) documentation for more details.

    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 filenames returned. If the encoding is set to 'buffer', the filenames returned will be passed as <Buffer> objects.

    If options.withFileTypes is set to true, the result will contain <fs.Dirent> objects.
