我有一个确认按钮，它实现了一个请求并重定向到另一个组件。我如何在导航到新组件之前等待数据？

const {
    isLoading,
    error,
    request
} = useHttp();

const confirmHandler = () => {
      request({
        url: API_PATH.create_coupledCertificates,
        method: "POST",
        contentType: "application/json",
        body: body,
      });
    }
    navigate(component, {
      state: { isLoading, error },
    });
  };

问题是，这样一来，isLoading和error变量就没有更新的值。

使用async/await语法：

const confirmHandler = async () => {
    await request({
        url: API_PATH.create_coupledCertificates,
        method: "POST",
        contentType: "application/json",
        body: body,
    });
    navigate(component, {
      state: { isLoading, error },
    });
  };

或Promise

const confirmHandler = () => {
    return request({
        url: API_PATH.create_coupledCertificates,
        method: "POST",
        contentType: "application/json",
        body: body,
    })
    .then(() => {
      navigate(component, {
        state: { isLoading, error },
      });
    }
  };
