fsPromises.realpath(path[, options])
path
<string> | <Buffer> | <URL>options
<string> | <Object>encoding
<string> 默认值:'utf8'
- 返回: <Promise>
仅支持可以转换为 UTF8 字符串的路径。
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(指定用于路径的字符编码)的对象。
如果 encoding
设置为 'buffer'
,则返回的路径将作为 Buffer
对象传入。
在 Linux 上,将 Node.js 与 musl libc 链接时,必须将 procfs 文件系统挂载在 /proc
上,此函数才能起作用。
Glibc 没有此限制。
path
<string> | <Buffer> | <URL>options
<string> | <Object>encoding
<string> Default:'utf8'
- Returns: <Promise>
Determines the actual location of path
using the same semantics as the
fs.realpath.native()
function then resolves the Promise
with the resolved
path.
Only paths that can be converted to UTF8 strings are supported.
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 path. If the encoding
is set to 'buffer'
, the path returned will be
passed as a Buffer
object.
On Linux, when Node.js is linked against musl libc, the procfs file system must
be mounted on /proc
in order for this function to work. Glibc does not have
this restriction.
