react native redux MapStateTrops状态更新,但不重新呈现演示器组件

国家在哪里有问题 mapDispatchToProps 似乎正在更新,但组件不会重新渲染以反映这些更改,即使。。。

• 演示者组件已正确连接到redux操作(可以成功 初始化 道具通过 mapDispatchToProps 打电话 mapDispatchToProps 功能(在任何情况下)
• 处理redux操作的redux reducer正在不可变地更新状态(这让我怀疑这是问题所在)( https://github.com/reduxjs/redux/issues/2190#issuecomment-271109542 )),即,减速器代码如下所示

const initialState = {
    session: {
        ...
        toUpdate: {success: false, processing: false, message: ''},
        ...
    },
    someOtherStateSections: {...},
    ...
}

const sessionReducer = (state=initialState.session, action) => {
    switch (action.type) {
        ...
        case Types.ACTION_TO_HANDLE:
                console.log(`REDUCER: ACTION_TO_HANDLE: check that state is being updating with intended values:\n${JSON.stringify(action, null, 2)}`)
                return Object.assign({}, state, {toUpdate: {
                    success: action.success,
                    processing: action.processing,
                    message: action.message,
                }})
        ...
    }
}

const rootReducer = combineReducers({
    session: sessionReducer,
    ...
})

export default rootReducer;

• 从reducer更新后,日志语句似乎显示 state 阿格。在 mapStateToProps 功能正在更新以反映这些更改。代码片段看起来像

const mapStateToProps = (state, ownProps) => {
    console.log(`PickupLocationAnchorFormContainer: mapStateToProps: ${JSON.stringify(state.session.pickupLocationAnchorChangeStatus, null, 2)}`)
    return {
        toUpdate: state.session.toUpdate,
        ownProps: ownProps,
    }
}

const mapDispatchToProps = (dispatch,) => {
  return {
    someThunk: (some, inputs) => {
      dispatch(someThunk(some, inputs))
    },
  }
}

const MyComponentContainer = connect(
  mapStateToProps,
  mapDispatchToProps
)(MyComponent)

export default MyComponentContainer

然而 MyComponent 似乎没有更新其 this.props.toUpdate 以获取更新的redux存储值。

• 更新后的状态值与旧值不同(在本例中, toUpdate.success 是从 false 到 true ),这让我怀疑这个问题与肤浅的平等性检查有关(参见 https://redux.js.org/faq/reactredux#why-isnt-my-component-re-rendering-or-my-mapstatetoprops-running )(虽然到目前为止还不能解决这个错误,但我知道什么,对吗?)

如有任何进一步的调试建议或推荐的解决方案,将不胜感激。
