fsPromises.mkdtemp(prefix[, options])
prefix
<string>options
<string> | <Object>encoding
<string> 默认值:'utf8'
- 返回: <Promise> 用包含新创建的临时目录的文件系统路径的字符串来满足。
创建唯一的临时目录。
通过在所提供的 prefix
的末尾附加六个随机字符来生成唯一的目录名称。
由于平台的不一致,请避免在 prefix
中尾随 X
字符。
某些平台,尤其是 BSD,可能返回六个以上的随机字符,并将 prefix
中的尾随 X
字符替换为随机字符。
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(指定要使用的字符编码)的对象。
import { mkdtemp } from 'node:fs/promises';
try {
await mkdtemp(path.join(os.tmpdir(), 'foo-'));
} catch (err) {
console.error(err);
}
fsPromises.mkdtemp()
方法会将六个随机选择的字符直接附加到 prefix
字符串。
例如,给定目录 /tmp
,如果要在 /tmp
内创建临时目录,则 prefix
必须以平台特定的尾随路径分隔符(require('node:path').sep
)结尾。
prefix
<string>options
<string> | <Object>encoding
<string> Default:'utf8'
- Returns: <Promise> Fulfills with a string containing the file system path of the newly created temporary directory.
Creates a unique temporary directory. A unique directory name is generated by
appending six random characters to the end of the provided prefix
. Due to
platform inconsistencies, avoid trailing X
characters in prefix
. Some
platforms, notably the BSDs, can return more than six random characters, and
replace trailing X
characters in prefix
with random characters.
The optional options
argument can be a string specifying an encoding, or an
object with an encoding
property specifying the character encoding to use.
import { mkdtemp } from 'node:fs/promises';
try {
await mkdtemp(path.join(os.tmpdir(), 'foo-'));
} catch (err) {
console.error(err);
}
The fsPromises.mkdtemp()
method will append the six randomly selected
characters directly to the prefix
string. For instance, given a directory
/tmp
, if the intention is to create a temporary directory within /tmp
, the
prefix
must end with a trailing platform-specific path separator
(require('node:path').sep
).
