buf.readUInt16BE([offset])
从指定的 offset
处的 buf
读取无符号的大端序 16 位整数。
此函数也可在 readUint16BE
别名下使用。
import { Buffer } from 'node:buffer';
const buf = Buffer.from([0x12, 0x34, 0x56]);
console.log(buf.readUInt16BE(0).toString(16));
// 打印: 1234
console.log(buf.readUInt16BE(1).toString(16));
// 打印: 3456
const { Buffer } = require('node:buffer');
const buf = Buffer.from([0x12, 0x34, 0x56]);
console.log(buf.readUInt16BE(0).toString(16));
// 打印: 1234
console.log(buf.readUInt16BE(1).toString(16));
// 打印: 3456
offset
<integer> Number of bytes to skip before starting to read. Must satisfy0 <= offset <= buf.length - 2
. Default:0
.- Returns: <integer>
Reads an unsigned, big-endian 16-bit integer from buf
at the specified
offset
.
This function is also available under the readUint16BE
alias.
import { Buffer } from 'node:buffer';
const buf = Buffer.from([0x12, 0x34, 0x56]);

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