Node.js stats.ctime 属性
stats.ctime属性是 fs.Stats 类的内置应用程序编程接口,用于获取上次更改文件状态时的时间戳。
句法:
stats.ctime
返回值:它返回一个日期值,表示上次更改文件状态时的时间戳。
以下示例说明了 Node.js 中 stats.ctime 属性的使用:
示例 1:
// Node.js program to demonstrate the
// stats.ctime property
// Accessing fs module
const fs = require('fs');
// Calling stats.ctime property from
// fs.Stats class using stat
fs.stat('./', (err, stats) => {
if (err) throw err;
// The timestamp when the file status
// has been changed last time
console.log("Using stat: " + stats.ctime);
});
// Using lstat
fs.lstat('./filename.txt', (err, stats) => {
if (err) throw err;
// The timestamp when the file status
// has been changed last time
console.log("Using lstat: " + stats.ctime);
});
输出:
Using stat: Sun Jun 21 2020 01:17:13 GMT+0530 (India Standard Time)
Using lstat: Sun Jun 21 2020 01:19:02 GMT+0530 (India Standard Time)
示例 2:
// Node.js program to demonstrate the
// stats.ctime property
// Accessing fs module
const fs = require('fs').promises;
// Calling fs.Stats stats.ctime
(async() => {
const stats = await fs.stat('./filename.txt');
// The timestamp when the file status
// has been changed last time
console.log("Using stat synchronous: "
+ stats.ctime);
})().catch(console.error)
输出:
(node:2748) ExperimentalWarning: The fs.promises API is experimental
Using stat synchronous: Sun Jun 21 2020 01:19:02 GMT+0530
(India Standard Time)
注意:以上程序将通过使用node filename.js
命令编译运行,并正确使用 file_path。
