Node.js fs.dirent.name 属性
原文:https://www . geesforgeks . org/node-js-fs-dirent-name-property/
fs。属性是类 fs 的内置应用编程接口。文件系统模块中的目录，用于提供特定目录的名称。
语法:
const dirent.name
参数:该属性不接受任何参数。 返回值:该属性返回特定目录的名称。
下面的程序说明了属性在 Node.js 中的使用:
示例 1: 文件名:index.js
java 描述语言
// Node.js program to demonstrate the
// dirent.name property
const fs = require('fs');
// Initiating asyn function
async function stop(path) {
// Creating and initiating dir's
// underlying resource handle
const dir = await
fs.promises.opendir(path);
// Synchronously reading the dir's
// underlying resource handle
// using readSync() method
for (var i = 0; i <= 6; i++) {
// Checking if the particular
// dirent is SymbolicLink or
// not by using name() method
const value = (dir.readSync()).name;
// Display the result
console.log(value);
}
}
// Catching error
stop('./').catch(console.error);
使用以下命令运行 index.js 文件:
node index.js
输出:
abcd.cer
cert.cer
certfile.cer
certificate1.cer
example.txt
features
filename.txt
示例 2: 文件名:index.js
java 描述语言
// Node.js program to demonstrate the
// dirent.name property
const fs = require('fs');
// Initiating asyn function
async function stop(path) {
let dir = null;
try {
// Creating and initiating directory's
// underlying resource handle
dir = await fs.promises.opendir(
new URL('file:///F:/java/'));
// Synchronously reading the File's
// underlying resource handle
// using readSync() method
for (var i = 0; i <= 3; i++) {
// Checking if the particular dirent
// is File or not by using isFile() method
const value = (dir.readSync()).name;
// Display the result
console.log(dir.readSync());
console.log(value);
}
} finally {
if (dir) {
// Display the result
console.log("dir is closed successfully");
// Synchronously closeSyncing the
// directory's underlying resource handle
const promise = dir.closeSync();
}
}
}
// Catching error
stop('./').catch(console.error);
使用以下命令运行 index.js 文件:
node index.js
输出:
Dirent { name: 'books.txt', [Symbol(type)]: 1 }
abcd.cer
Dirent { name: 'certfile.cer', [Symbol(type)]: 1 }
cert.cer
Dirent { name: 'example.com_index.html', [Symbol(type)]: 1 }
certificate1.cer
Dirent { name: 'features', [Symbol(type)]: 2 }
