这是我的组件。该容器是：它是否反对redux哲学将复制状态复制到本地状态？
import { connect } from 'react-redux'
import * as PassagesActions from '../actions/passages'
import PassageMain from '../components/passage/main'
const mapStateToProps = (state) => {
return {
passageState: state.PassageReducer
}
}
const mapDispatchToProps = (dispatch) => {
return {
fetchPassages:() => {
const params = {
url: `${process.env.REACT_APP_API_ENDPOINT}/passages`
}
dispatch(PassagesActions.fetchData(params, 'passages'))
},
fetchPassage: (passageId) => {
const params = {
url: `${process.env.REACT_APP_API_ENDPOINT}/passages/${passageId}`
}
dispatch(PassagesActions.fetchData(params, 'passage'))
}
}
}
export default connect(
mapStateToProps, mapDispatchToProps
)(PassageMain)
所以你可以看到，在我的componentDidMount，我做的API调用（通过终极版）和componentWillReceiveProps，我认为复制到我的本地状态。这个想法是，如果我对我的passage进行更改，它是在组件级完成的，那么我可以通过一些尚未创建的redux操作将该对象传回。
这是可接受的在REDX哲学？我仍然围绕着REDX，所以我很抱歉如果这个问题没有意义。
