fsPromises.readlink(path[, options])

异步的 readlink(2)

可选的 options 参数可以是指定编码的字符串,也可以是具有 encoding 属性(指定用于返回的链接路径的字符编码)的对象。 如果将 encoding 设置为 'buffer',则返回的链接路径将作为 Buffer 对象传入。

Asynchronous readlink(2). 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.
