I dispatch an effects request in the component, store the asynchronous data in state, and then get the data through this.props.xxx.xxx in the render in the component (it seems to be triggered several times, there is no data in the previous times, and the rendering is judged to be empty). Now there is a load more, click to trigger dispatch, again when the this.props.xxx.xxx data changes, but does not seem to start the page update. However, after dispatch, it is impossible to this.setState to state. What can we do about this?
