如何在不等待整个文件的情况下将可读流传输到URL.createObjectURL中？

// 1. 创建可读流对象
const response = await fetch('your_file_url');
const reader = response.body.getReader();

// 2. 创建空的Blob对象
const chunks = [];
let receivedLength = 0;

// 3. 创建WritableStream对象
const writableStream = new WritableStream({
  write(chunk) {
    chunks.push(chunk);
    receivedLength += chunk.length;
  },
});

// 4. 将可读流数据写入Blob对象
await reader.read().then(function processResult(result) {
  if (result.done) {
    const blob = new Blob(chunks);

    // 5. 将Blob转换为ArrayBuffer
    return blob.arrayBuffer();
  }

  writableStream.write(result.value);
  return reader.read().then(processResult);
});

// 6. 将ArrayBuffer转换为URL
const url = URL.createObjectURL(new Blob([chunks]));
