Node.js fs。目录路径()方法
原文:https://www.geeksforgeeks.org/node-js-fs-dir-path-method/
fs。Dir.path() 方法是类 fs 的内置应用编程接口。文件系统模块中的目录，用于获取目录的路径。 语法:
const dir.path
参数:此方法不接受任何参数。 返回值:此方法返回目录的路径。 以下程序说明了 fs 的使用。Dir.path() 方法。 示例 1: 文件名:index.js
java 描述语言
// Node.js program to demonstrate the
// dir.path() method
const fs = require('fs');
// Initiating async function
async function stop(path) {
// Creating and initiating directory's
// underlying resource handle
const dir = await fs.promises.opendir(path);
console.log("All the dirent before operation :- ");
for (var i = 0; i <= 2; i++) {
console.log(((dir.readSync())).name);
}
// Getting the path of the directory
// by using path() method
const pathval = dir.path;
console.log("All the dirent after operation :- ");
for (var i = 0; i <= 2; i++) {
console.log(((dir.readSync())).name);
}
// Display the result
console.log("\nPath :- " + pathval);
}
// Catching error
stop('./').catch(console.error);
使用以下命令运行 index.js 文件:
node index.js
输出:
All the dirent before operation :-
books.txt
datastore.json
example.txt
All the dirent after operation :-
index.js
node_modules
package-lock.json
Path :- ./
示例 2: 文件名:index.js
java 描述语言
// Node.js program to demonstrate the
// dir.path() method
const fs = require('fs');
const fsPromises = fs.promises;
// Name of the directory to be created
let directo = './temp';
// Checking if the directory is
// present or not
if (!fs.existsSync(directo)) {
fs.mkdirSync(directo);
}
// Initiating asyncrionise function
async function funct(path) {
// Initializng dir
let dir = null;
let pathval = null;
try {
// Creating and initiating directory's
// underlying resource handle
dir = await fs.promises.opendir('./');
console.log("All the dirent before operation :- " +
((dir.readSync())));
// Getting the path of the directory
// by using path() method
pathval = dir.path;
} finally {
if (dir) {
// Close the file if it is opened.
console.log("Path :- " + pathval);
console.log("All the dirent after operation :- " +
((dir.readSync())));
await dir.close();
}
}
}
funct('./').catch(console.error);
使用以下命令运行 index.js 文件:
node index.js
输出:
All the dirent before operation :- [object Object]
Path :- ./
All the dirent after operation :- [object Object]
