HarmonyOS Http使用问题？

Question

有一个RequestParams数组：

export class RequestParams {
  key : string = ''
  value: string|number = '';
}

会作为参数传给httpRequest方法，但现在作为extraData传入，请求参数会有问题，请问要怎么写？

export function httpRequest(method: http.RequestMethod, url: string, payload?: RequestParams[]): Promise<ApiResponse> {
  let httpRequest = http.createHttp();
  let responseResult = httpRequest.request(url, {
    method: method,
    readTimeout: Const.HTTP_READ_TIMEOUT,
    header: {
    },
    connectTimeout: Const.HTTP_READ_TIMEOUT,
    extraData: payload
  });

关于extradata的用法可参考：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-http-V5\#httprequestoptions

支持跨平台，表格中extradata的说明，demo可参考：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-http-V5\#完整示例
