考慮這種情況：
應用程序加載=>從API獲取JSON =>需要修改JSON返回終極版，取何地使用.MAP
在這種情況下，我使用的時刻做出一些日期修改和做一些分組，我將在UI中使用。我看着堆棧，發現一個similar question，但不覺得它提供了我正在尋求的清晰度。
我應該在哪裏使用.MAP創建包含格式化的&分組日的新對象？我應該在調用之前操作api調用中的原始json還是在redux操作中？最佳做法是什麼？
是否確定添加屬性和變異的對象，因爲我在下面顯示，
service["mStartDate"] = mStartDate之前，我把數據放到我的店裏，並把它當作一成不變的狀態？
第一種方法 - 在API調用
class TicketRepository extends BaseRepository {
getDataByID(postData) {
return this.post('api/lookup', postData)
.then(result => {
const groupedData = {}
return result.map(ticket => {
const mStartDate = moment(ticket.startDate)
const mEndDate = moment(ticket.endDate)
const serviceLength = mStartDate.diff(mEndDate,'hours')
const duration = moment.duration(serviceLength,"hours").humanize()
const weekOfYear = mStartDate.format('WW')
const dayOfWeek = mStartDate.format("d")
if(!groupedData.hasOwnProperty(weekOfYear)){
groupedData[weekOfYear] = {}
}
if (!groupedData[weekOfYear].hasOwnProperty(dayOfWeek)) {
groupedData[weekOfYear][dayOfWeek] = []
}
service["mStartDate"] = mStartDate
service["mEndDate"] = mEndDate
service["serviceLength"] = serviceLength
service["duration"] = duration
groupedData[weekOfYear][dayOfWeek].push(service)
})
})
}
}
第二個方法改變原始JSON，做一個簡單的API調用
class TicketRepository extends BaseRepository {
getDataByID(postData) {
return this.post('api/lookup', postData)
}
}
更改動作的JSON調度
export function getDataByID() {
return (dispatch, getState) => {
dispatch(dataLookupRequest())
const state = getState()
const groupedData = {}
return TicketRepository.getDataByID(userData)
.then(result => {
const groupedData = {}
return result.map(ticket => {
const mStartDate = moment(ticket.startDate)
const mEndDate = moment(ticket.endDate)
const serviceLength = mStartDate.diff(mEndDate,'hours')
const duration = moment.duration(serviceLength,"hours").humanize()
const weekOfYear = mStartDate.format('WW')
const dayOfWeek = mStartDate.format("d")
if(!groupedData.hasOwnProperty(weekOfYear)){
groupedData[weekOfYear] = {}
}
if (!groupedData[weekOfYear].hasOwnProperty(dayOfWeek)) {
groupedData[weekOfYear][dayOfWeek] = []
}
service["mStartDate"] = mStartDate
service["mEndDate"] = mEndDate
service["serviceLength"] = serviceLength
service["duration"] = duration
groupedData[weekOfYear][dayOfWeek].push(service)
})
return groupedData
})
.then(groupedData => {
dispatch(lookupSuccess(groupedData))
})
.catch(err => dispatch(dataLookupFailure(err.code, err.message)))
}
}
