在javascript中将Uint8Array转换为字符串

const uint8Array = new Uint8Array([72, 101, 108, 108, 111]);
const decoder = new TextDecoder();
const string = decoder.decode(uint8Array);
console.log(string); // 输出: "Hello"

const uint8Array = new Uint8Array([72, 101, 108, 108, 111]);
const string = String.fromCharCode.apply(null, uint8Array);
console.log(string); // 输出: "Hello"

const uint8Array = new Uint8Array([72, 101, 108, 108, 111]);
const encoder = new TextEncoder();
const base64String = btoa(String.fromCharCode.apply(null, encoder.encode(uint8Array)));
console.log(base64String); // 输出: "SGVsbG8="
