HarmonyOS next系统请求后端交易，如何保存cookie

private header: Header = new Header(); 
 
class Header { 
  public contentType: string = 'application/json'; 
  public cookie: string = '' 
} 
 
request() { 
  let httpRequest = http.createHttp(); 
 
  httpRequest.request( 
    // 填写HTTP请求的URL地址，可以带参数也可以不带参数。URL地址需要开发者自定义。请求的参数可以在extraData中指定 
    this.url, 
    { 
      method: http.RequestMethod.GET, // 可选，默认为http.RequestMethod.GET 
      // 开发者根据自身业务需要添加header字段 
      header: this.header, 
    }, (err: BusinessError, data: http.HttpResponse) => { 
    if (!err) { 
      // 从返回中拿到存放在cookies中的set-cookie值，并将JSESSIONID设置到请求头中，下次请求即可带上sessionId 
      console.info('cookies:' + JSON.stringify(data.cookies)); // 8+ 
      if (data.cookies) { 
        let temp:string = data.header['set-cookie'][0] 
        let cookies = temp.split(';') 
        cookies.forEach(item => { 
          if (item.indexOf("JSESSIONID") > -1) { 
            this.header.cookie = item 
          } 
        }) 
      } 
      // 当该请求使用完毕时，调用destroy方法主动销毁 
      httpRequest.destroy(); 
    } else { 
      console.error('error:' + JSON.stringify(err)); 
      // 在请求有问题时清空cookie 
      this.header.cookie = '' 
      // 取消订阅HTTP响应头事件 
      httpRequest.off('headersReceive'); 
      // 当该请求使用完毕时，调用destroy方法主动销毁 
      httpRequest.destroy(); 
    } 
  } 
  ); 
}

private sessionConfig: rcp.SessionConfiguration = { 
  cookies: {},
