fetch缓存问题

if (window.fetch && method == ‘fetch‘) {
        let requestConfig = {
            credentials: ‘include‘,
            method: type,
            headers: {
                ‘Accept‘: ‘application/json‘,
                ‘Content-Type‘: ‘application/json‘,
                ‘Authorization‘:"Bearer " + localStorage.getItem("access_token2"),//gougou 2021-5-12
            },
            mode: "cors",
            //cache: "force-cache"//会有缓存
            cache:"no-cache"
        }

        if (type == ‘POST‘ || type == ‘DELETE‘) {
            Object.defineProperty(requestConfig, ‘body‘, {
                value: JSON.stringify(data)
            })
        }
