React redux 没有更新组件

Question

React 应用程序在减少新状态后不会更新组件。第一次渲染后，无论我做什么，反应组件都没有更新。我试图在减速器中找到一些状态突变，但有 none。我不知道有什么问题。

这是回购协议：https://github.com/ithrasil/rainbeat/tree/bug

如有任何帮助，我将不胜感激

减速器之一：

export default function(
state={ 
    received: false,
    status: false, 
  primaryList: [], 
  secondaryList: [], 
  query: "" 
}, 
action) {

switch(action.type) {

case "RECEIVE_STATUS":
  state.received = action.payload;
  break;

    case "SEARCH_STATUS":
        state.status = action.payload;
        break;

    case "PRIMARY_LIST_UPDATE":
        state.primaryList = action.payload;
        break;

    case "SECONDARY_LIST_UPDATE":
        state.secondaryList = action.payload;
        break;

    case "QUERY_UPDATE":
        state.query = action.payload;
        localStorage.setItem('query', action.payload);
        break;
    }

    return state;
}

你正在改变状态。这就是您的组件未呈现的原因

export default function(state={ id: 0 }, action) {
 var newState; 
   switch(action.type) {
        case "CHANGE_CARD":
          newState={...state, id: action.payload}
          break;
      }

      return newState;
    }
