字符串路径

字符串路径被解释为标识绝对或相对文件名的 UTF-8 字符序列。 相对路径将相对于通过调用 process.cwd() 确定的当前工作目录进行解析。

在 POSIX 上使用绝对路径的示例：

import { open } from 'node:fs/promises';

let fd;
try {
  fd = await open('/open/some/file.txt', 'r');
  // 对文件做一些事情
} finally {
  await fd.close();
}

在 POSIX 上使用相对路径的示例（相对于 process.cwd()）:

import { open } from 'node:fs/promises';

let fd;
try {
  fd = await open('file.txt', 'r');
  // 对文件做一些事情
} finally {
  await fd.close();
}

String paths are interpreted as UTF-8 character sequences identifying the absolute or relative filename. Relative paths will be resolved relative to the current working directory as determined by calling process.cwd().

Example using an absolute path on POSIX:

import { open } from 'node:fs/promises';

let fd;
try {
  fd = await open('/open/some/file.txt', 'r');
  // Do something with the file
} finally {
  await fd.close();
}

Example using a relative path on POSIX (relative to process.cwd()):

import { open } from 'node:fs/promises';

let fd;
try {
  fd = await open('file.txt', 'r');
  // Do something with the file
} finally {
  await fd.close();
}
