fsPromises.realpath(path[, options])
path
<string> | <Buffer> | <URL>options
<string> | <Object>encoding
<string> 默认值:'utf8'
- 返回: <Promise> 成功时将使用解析的路径履行。
使用与 fs.realpath.native()
函数相同的语义确定 path
的实际位置。
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> Fulfills with the resolved path upon success.
Determines the actual location of path
using the same semantics as the
fs.realpath.native()
function.
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.
