我正在使用 fetch ，如此处所示（使用 fetch 而不是 ajax 和 redux-observable）在服务器端使用节点进行 fetch。不幸的是，AjaxObservable 只能在浏览器中工作，所以我使用 isomorphic-fetch 在服务器上进行 fetch。

我的代码看起来像这样：

            let fetch$ = null;
            if (canUseDOM) {
                fetch$ = AjaxObservable.create({
                    url,
                    method: 'GET',
                    responseType: 'json',
                    ...options
                }).takeUntil(action$.ofType(`${type}_CANCEL`));
            } else {
                fetch$ = Observable.from(fetch(url, options).then(response => {
                    return response.json()
                }).then(response => ({response})));
            }

            return fetch$
                .map(({response: payload}) => ({type, payload}))

但是，当我在服务器（即canUseDOM == false）上运行它时，我收到以下错误：
