options

1. sequential，是否顺序执行

)

export function fetchPageBaseInfo(pageId) {
    return {
        type: types.FETCH_PAGE_BASE_INFO,
        url: `/dva/api/pages-history/${pageId}`,
        sequential: true,//promise来支持顺序
        callbactions: (result) => {
            const {id, Scene, pageConfig, host} = result
            return [
                createQRCodePreview({pageKind: 'page', pageId: id, host}),
                getCurrentScene(Scene),
                // 因显示widget和setting和content具有依赖性，故此顺序
                fetchWidgets(pageConfig),
                fetchSettings({pageId: id, pageKind: 'page', ...pageConfig}),
                fetchSections({pageId: id, pageKind: 'page'})
            ]
        }
    }
}
