import { resetShare } from 'utils/wxUtil'

const initialData = {
	shareStatus: false,
	goods: {}
}

export default function (state = initialData, action) {
	switch (action.type) {
		case 'SHARE_SHOW':
			return {
				shareStatus: true,
				goods: action.goods
			}
		case 'SHARE_HIDE':
			resetShare()
			return {
				shareStatus: false,
				goods: {}
			}
		default:
			return state
	}
}

所有action都会进入default，此时一定要回传state
