Node.js fs.lstatSync()方法

原文:https://www.geeksforgeeks.org/node-js-fs-lstatsync-method/

fs.lstatSync()方法用于同步返回用于引用文件或目录的符号链接的信息。fs。Stat 对象返回几个字段和方法来获取文件的更多细节。

语法:

fs.lstatSync( path, options )

参数:该方法接受两个参数，如上所述，如下所述:

Path: It is a String, Buffer or URL that holds the path of symbolic link.
Option: is an object that can be used to specify optional parameters that affect output. It has an optional parameter:
- bigint: It is a Boolean value that specifies whether the value returned in fs is. The Stats object is bigint. The default value is false.

返回:返回一个 fs。包含符号链接详细信息的 Stats 对象。

以下示例说明了 Node.js 中的 fs.lstatSync()方法:

示例 1: 本示例使用 fs.lstatSync()方法获取文件符号链接的详细信息。

// Node.js program to demonstrate the
// fs.lstatSync() method

// Import the filesystem module
const fs = require('fs');

fs.symlinkSync(__dirname + "\\example_file.txt",
                       "symlinkToFile", 'file');

console.log("Symlink to file created")

statsObj = fs.lstatSync("symlinkToFile");

console.log("Stat of symlinkToFile")
console.log(statsObj);

输出:

Symlink to file created
Stat of symlinkToFile
Stats {
  dev: 3229478529,
  mode: 41398,
  nlink: 1,
  uid: 0,
  gid: 0,
  rdev: 0,
  blksize: 4096,
  ino: 281474976780954,
  size: 49,
  blocks: 0,

  mtimeMs: 1585207963423.2476,
  ctimeMs: 1585207963423.2476,
  birthtimeMs: 1585207963423.2476,

  birthtime: 2020-03-26T07:32:43.423Z
}

示例 2: 本示例使用 fs.lstatSync()方法获取指向文件夹的符号链接的详细信息。

// Node.js program to demonstrate the
// fs.lstatSync() method

// Import the filesystem module
const fs = require('fs');

fs.symlinkSync(__dirname + "\\example_directory",
                          "symlinkToDir", 'dir');

console.log("Symlink to directory created")

statsObj = fs.lstatSync("symlinkToDir");
console.log("Stat of symlinkToDir")
console.log(statsObj);

输出:

Stat of symlinkToDir
Stats {
  dev: 3229478529,
  mode: 41398,
  nlink: 1,
  uid: 0,
  gid: 0,
  rdev: 0,
  blksize: 4096,
  ino: 281474976780955,
  size: 50,
  blocks: 0,
  atimeMs: 1585208001112.3284,
  mtimeMs: 1585208001112.3284,
  ctimeMs: 1585208001112.3284,
  birthtimeMs: 1585208001112.3284,
  atime: 2020-03-26T07:33:21.112Z,
  mtime: 2020-03-26T07:33:21.112Z,
  ctime: 2020-03-26T07:33:21.112Z,
  birthtime: 2020-03-26T07:33:21.112Z
}
