Node.js fs.Dir.path() 方法

fs.Dir.path()方法是文件系统模块中fs.Dir类的内置应用程序编程接口，用于获取目录的路径。

句法：

const dir.path

参数：此方法不接受任何参数。
返回值：该方法返回目录的路径。

下面的程序说明了fs.Dir.path()方法的使用。

示例 1：文件名：index.js

Javascript

// 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

Javascript

// 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) {
 
    // Initializing 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]
