#鸿蒙学习大百科#如何解析身份验证后的verifyToken？

import { buffer } from '@kit.ArkTS';
 function decodeBase64(data: string):string {
  return buffer.from(data, 'base64').toString('utf8');
}

function decodeIdToken(token: string):void {
  const parts = token.split('.');
  if (parts.length !== 3) {
    console.error('format of idToken is inValid');
    return;
  }
  let idTokenObj: Record<string, Object> = {};
  idTokenObj['header'] = JSON.parse(decodeBase64(parts[0]));
  idTokenObj['payload'] = JSON.parse(decodeBase64(parts[1]));
  idTokenObj['signature'] = parts[2];
  // 授权后的nonce可以从idTokenObj中解析出来
  let payLoad: Record<string, string> = idTokenObj['payload'] as Record<string, string>;
  let data: string = payLoad['data'];
  let nonce: string = JSON.parse(data).nonce;
  // 开发者处理nonce
}
