fsPromises.mkdtemp(prefix[, options])
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。
fsPromises.mkdtemp(path.join(os.tmpdir(), 'foo-'))
.catch(console.error);
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('path').sep
)结尾。
Creates a unique temporary directory and resolves the Promise
with the created
directory path. 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.
fsPromises.mkdtemp(path.join(os.tmpdir(), 'foo-'))
.catch(console.error);
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('path').sep
).
