Node.js Buffer buf.equals(otherBuffer)用法及代码示例

buf.equals(otherBuffer)

参数

• otherBuffer <Buffer> | <Uint8Array> A Buffer 或 Uint8Array 与之比较 buf 。
• 返回： <boolean>

如果 buf 和 otherBuffer 具有完全相同的字节，则返回 true，否则返回 false。等效于 buf.compare(otherBuffer) === 0 。

import { Buffer } from 'node:buffer';

const buf1 = Buffer.from('ABC');
const buf2 = Buffer.from('414243', 'hex');
const buf3 = Buffer.from('ABCD');

console.log(buf1.equals(buf2));
// Prints: true
console.log(buf1.equals(buf3));
// Prints: falseconst { Buffer } = require('node:buffer');

const buf1 = Buffer.from('ABC');
const buf2 = Buffer.from('414243', 'hex');
const buf3 = Buffer.from('ABCD');

console.log(buf1.equals(buf2));
// Prints: true
console.log(buf1.equals(buf3));
// Prints: false
