关于node中将 ArrayBuffer 对象中 [Uint8Contents] 提取出来

Question

ArrayBuffer {
[Uint8Contents]: <4d 57 a3 05 b7 53 0c 6c fa d6 e6 ed 41 d4 c8 53 61 0a ae f4 5e 04 16 b9 35 db e8 2d 73 3d 24 b2>,
byteLength: 32
}

Answer 1

Array.prototype.slice.call(new Uint8Array(arraybuffer))

示例

var data = '4d 57 a3 05 b7 53 0c 6c fa d6 e6 ed 41 d4 c8 53 61 0a ae f4 5e 04 16 b9 35 db e8 2d 73 3d 24 b2'.split(' ').map(i => parseInt(i, 16));
var buffer = Buffer.from(data);
var array = new Uint8Array(buffer);
var arraybuffer = array.buffer;
console.log(arraybuffer)
var arr2 = Array.prototype.slice.call(new Uint8Array(arraybuffer));
console.log(arr2);
