在React本机中将Base64字符串转换为blob

import React from "react";

class Base64ToBlob extends React.Component {
  convertBase64ToBlob(base64String) {
    const byteString = atob(base64String);
    const arrayBuffer = new ArrayBuffer(byteString.length);
    const uint8Array = new Uint8Array(arrayBuffer);

    for (let i = 0; i < byteString.length; i++) {
      uint8Array[i] = byteString.charCodeAt(i);
    }

    const blob = new Blob([uint8Array], { type: "application/octet-stream" });
    const blobUrl = URL.createObjectURL(blob);

    return blobUrl;
  }

  render() {
    const base64String = "Base64字符串";
    const blobUrl = this.convertBase64ToBlob(base64String);

    return (
      <div>
        <a href={blobUrl} download>下载Blob文件</a>
        <img src={blobUrl} alt="Blob图片" />
      </div>
    );
  }
}

export default Base64ToBlob;
