buf.readUInt16BE([offset])

• offset <integer> 开始读取之前要跳过的字节数。必须满足 0 <= offset <= buf.length - 2。默认值：0。

  ¥offset <integer> Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - 2. Default: 0.

• 返回：<integer>

  ¥Returns: <integer>

从指定的 offset 处的 buf 读取无符号的大端序 16 位整数。

¥Reads an unsigned, big-endian 16-bit integer from buf at the specified offset.

此函数也可在 readUint16BE 别名下使用。

¥This function is also available under the readUint16BE alias.

import { Buffer } from 'node:buffer';

const buf = Buffer.from([0x12, 0x34, 0x56]);

console.log(buf.readUInt16BE(0).toString(16));
// Prints: 1234
console.log(buf.readUInt16BE(1).toString(16));
// Prints: 3456const { Buffer } = require('node:buffer');

const buf = Buffer.from([0x12, 0x34, 0x56]);

console.log(buf.readUInt16BE(0).toString(16));
// Prints: 1234
console.log(buf.readUInt16BE(1).toString(16));
// Prints: 3456拷贝
