Angular:类型ArrayBuffer不能赋值给类型string

// 创建一个ArrayBuffer
const buffer = new ArrayBuffer(8);
const view = new Uint8Array(buffer);
view[0] = 72; // H
view[1] = 101; // e
view[2] = 108; // l
view[3] = 108; // l
view[4] = 111; // o

// 使用TextDecoder进行解码
const decoder = new TextDecoder();
const result = decoder.decode(buffer);
console.log(result); // 输出 "Hello"

// 手动解码
let result = '';
for (let i = 0; i < buffer.byteLength; i++) {
  result += String.fromCharCode(view[i]);
}
console.log(result); // 输出 "Hello"
