节点. js stats.mode 属性来自 fs。统计等级
原文:https://www . geesforgeks . org/node-js-stats-mode-property-from-fs-stats-class/
stats.mode 属性是 fs 的内置应用编程接口。Stats 类，用于获取文件类型和模式作为位字段。
语法:
stats.mode;
返回值:它返回一个数字或 BigInt 值，表示描述文件类型和模式的位字段。
下面的例子说明了 stats.mode 在 Node.js 中的使用:
例 1:
// Node.js program to demonstrate the
// stats.mode property
// Accessing fs module
const fs = require('fs');
// Calling fs.Stats stats.mode for files
// using stat
fs.stat('./filename.txt', (err, stats) => {
if (err) throw err;
console.log("using stat: the type and "
+ "mode bit-field of the file is "
+ stats.mode);
});
// Using lstat
fs.lstat('./filename.txt', (err, stats) => {
if (err) throw err;
console.log("using lstat: the type and "
+ "mode bit-field of the file is "
+ stats.mode);
});
// For directories
// Using stat
fs.stat('./', (err, stats) => {
if (err) throw err;
console.log("using stat: the type and "
+ "mode bit-field of the file is "
+ stats.mode);
});
// Using lstat
fs.lstat('./', (err, stats) => {
if (err) throw err;
console.log("using lstat: the type and "
+ "mode bit-field of the file is "
+ stats.mode);
});
输出:
using stat: the type and mode bit-field of the file is 33206
using lstat: the type and mode bit-field of the file is 33206
using stat: the type and mode bit-field of the file is 16822
using lstat: the type and mode bit-field of the file is 16822
例 2:
// Node.js program to demonstrate the
// stats.mode property
// Accessing fs module
const fs = require('fs').promises;
// Calling fs.Stats stats.mode
(async() => {
const stats = await fs.stat('./filename.txt');
console.log("using stat synchronous: the type "
+ "and mode bit-field of the file is "
+ stats.mode);
})().catch(console.error)
输出:
(node:9448) ExperimentalWarning: The fs.promises API
is experimental
using stat synchronous: the type and mode bit-field
of the file is 33206
注意:以上程序使用node filename.js命令编译运行，正确使用 file_path。
