export const login = accesstoken => dispatch => {
return fetch("https://cnodejs.org/api/v1/accesstoken", {
method: "POST",
body: JSON.stringify({ accesstoken })
}).then(res => {
if (res.ok) {
return res.json()
} else {
return Promise.reject(res.statusText)
}
}).then(({
loginname
}) => Promise.resolve(loginname))
}as above, the native Fetch interface of the browser is used, but because the cross-domain POST request is involved, the OPTIONS request is not sent in advance, so 401 is returned directly. Is there any better solution?
