fsPromises.readlink(path[, options])
path
<string> | <Buffer> | <URL>options
<string> | <Object>encoding
<string> 默认值:'utf8'
- 返回: <Promise> 成功时将使用
linkString
履行。
读取 path
引用的符号链接的内容。

文档。
成功时使用 linkString
解决 promise。
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

,则返回的链接路径将作为 <Buffer> 对象传入。
path
<string> | <Buffer> | <URL>options
<string> | <Object>encoding
<string> Default:'utf8'
- Returns: <Promise> Fulfills with the
linkString
upon success.
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.
