如何将arraybuffer转换为json？

我想做一个镀铬的分机。我需要得到请求有效负载并获取它。我得到了这样请求的数据：
ArrayBuffer(439) {}
[[Int8Array]]: Int8Array(439) [123, 34, 99, 114, 97, 119, 108, 101, 114, 73, 110, 102, 111, 34, 58, 34, 48, 97, 110, 65, 102, 120, 110, 100, 103, 79, 71, 111, 89, 57, 69, 82, 71, 71, 115, 80, 104, 67, 68, 86, 50, 100, 114, 118, 116, 113, 102, 68, 86, 51, 76, 66, 113, 121, 102, 84, 69, 100, 105, 115, 115, 79, 80, 68, 120, 122, 81, 56, 95, 101, 106, 89, 89, 106, 68, 70, 110, 73, 65, 82, 117, 82, 99, 111, 119, 114, 67, 88, 114, 97, 109, 101, 45, 57, 69, 50, 111, 52, 109, 54, …]

正如@wOxxOm所说，将其转换为字符串，然后解析它。
注意:这将不适用于IE (也可能是Edge )。
// Obviosuly replace this with whatever your array buffer is
const arrayBuffer = new TextEncoder().encode(JSON.stringify({crawlerInfo: "crawler info"}))
const json = JSON.parse(new TextDecoder().decode(arrayBuffer))
console.log(json)
