fs.realpath.native(path[, options], callback)
path
<string> | <Buffer> | <URL>options
<string> | <Object>encoding
<string> 默认值:'utf8'
callback
<Function>
异步的 realpath(3)
。
callback
有两个参数 (err, resolvedPath)
。
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(指定用于传给回调的路径的字符编码)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'
callback
<Function>
Asynchronous realpath(3)
.
The callback
gets two arguments (err, resolvedPath)
.
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 passed to the callback. 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.
