buf.readUInt32BE([offset])

• offset <integer> 开始读取之前要跳过的字节数。必须满足 0 <= offset <= buf.length - 4。默认值:0。

  \offset <integer> Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - 4. Default: 0.

• 返回:<integer>

  \Returns: <integer>

从指定的 offset 处的 buf 读取无符号的大端序 32 位整数。

\Reads an unsigned, big-endian 32-bit integer from buf at the specified offset.

此函数也可在 readUint32BE 别名下使用。

\This function is also available under the readUint32BE alias.

import { Buffer } from 'node:buffer';
const buf = Buffer.from([0x12, 0x34, 0x56, 0x78]);
console.log(buf.readUInt32BE(0).toString(16));
// Prints: 12345678const { Buffer } = require('node:buffer');
const buf = Buffer.from([0x12, 0x34, 0x56, 0x78]);
console.log(buf.readUInt32BE(0).toString(16));
// Prints: 12345678拷贝
