fsPromises.mkdtemp(prefix[, options])

• prefix <string>

• options <string> | <Object>

  • encoding <string> 默认值：'utf8'

    ¥encoding <string> Default: '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。

  ¥Returns: <Promise> Fulfills with a string containing the filesystem path of the newly created temporary directory.

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。

¥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.

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。

¥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);
} 拷贝

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，给定一个目录 /tmp，如果打算在 /tmp 中创建一个临时目录，则 prefix 必须以尾随的特定于平台的路径分隔符 (require('node:path').sep) 结尾。

¥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).
