buf.readUInt32LE([offset])
从指定的 offset 处的 buf 读取无符号的小端序 32 位整数。
此函数也可在 readUint32LE 别名下使用。
const buf = Buffer.from([0x12, 0x34, 0x56, 0x78]);
console.log(buf.readUInt32LE(0).toString(16));
// 打印: 78563412
console.log(buf.readUInt32LE(1).toString(16));
// 抛出 ERR_OUT_OF_RANGE。offset<integer> Number of bytes to skip before starting to read. Must satisfy0 <= offset <= buf.length - 4. Default:0.- Returns: <integer>
Reads an unsigned, little-endian 32-bit integer from buf at the specified
offset.
This function is also available under the readUint32LE alias.
const buf = Buffer.from([0x12, 0x34, 0x56, 0x78]);
console.log(buf.readUInt32LE(0).toString(16));
// Prints: 78563412
console.log(buf.readUInt32LE(1).toString(16));
// Throws ERR_OUT_OF_RANGE.
