HarmonyOS rcp如何跳过https证书验证

我的代码如下，但是无效，报错“code”:1007900060,“data”:“SSL peer certificate or SSH remote key was not OK”

private requestConfiguration(): rcp.Configuration {
  return {
    transfer: {
      timeout: {
        connectMs: QDCommonConstants.HTTP_TIMEOUT,
        transferMs: QDCommonConstants.HTTP_TIMEOUT,
      },
    },
    dns: {
      dnsOverHttps: {
        url: QDCtxConfig.getHref(), 
        skipCertificatesValidation: true,
      }
    }
  }
}

let req = new rcp.Request(url);
if (params) {
  let arr = Object.keys(params)
  if (arr.length > 0) {
    req.content = new rcp.Form(params)
    req.method = method.toUpperCase()
  }
}
req.headers = this.header(url)
req.configuration = this.requestConfiguration()
let resp: rcp.Response = await QDHttpRequest.session.fetch(req)
