Node.js fsPromises.mkdir()方法
原文:https://www . geesforgeks . org/node-js-fspromises-mkdir-method/
fsPromises.mkdir() 方法用于异步创建一个目录,然后解析promises,如果递归为真,则解析第一个创建的目录路径。
语法:
fsPromises.mkdir(path, options)
参数:该方法接受两个参数,如上所述,如下所述:
- Path: This parameter is a String, Buffer or URL, which holds the path of the directory that must be created.
- option: is an object or an integer?
- Recursion: This parameter holds a recursive Boolean value. By default, it is false.
- mode: mode option is used to set directory permissions, and the default is 0777. Is it a string or an integer
返回值:它返回承诺对象,该对象表示异步操作的最终完成(或失败)及其结果值。
下面的例子说明了 Node.js 中 fsPromises.mkdir() 方法的使用
例:
// Node.js program to demonstrate
// the fsPromises.mkdir() Method
// Include fs and path module
const fs = require('fs');
const fsPromises = fs.promises;
fsPromises.mkdir('fs_test2').then(function() {
console.log('Directory created successfully');
}).catch(function() {
console.log('failed to create directory');
});
输出:
Directory created successfully!
