buf.readUInt16LE([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
  • 返回: <integer>

从指定的 offset 处的 buf 读取无符号的小端序 16 位整数。

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

console.log(buf.readUInt16LE(0).toString(16));
// 打印: 3412
console.log(buf.readUInt16LE(1).toString(16));
// 打印: 5634
console.log(buf.readUInt16LE(2).toString(16));
// 抛出 ERR_OUT_OF_RANGE。
  • offset <integer> Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - 2. Default: 0.
  • Returns: <integer>

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

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

console.log(buf.readUInt16LE(0).toString(16));
// Prints: 3412
console.log(buf.readUInt16LE(1).toString(16));
// Prints: 5634
console.log(buf.readUInt16LE(2).toString(16));
// Throws ERR_OUT_OF_RANGE.
