摘要：引入引入組件和綁定結構頁面組件這個組件引入做連接引入中的函數到中處理數據獲取中的數據組件上會受到發來的數據包含發來的信息定義函數定義字段字符串定義的函數返回一個高階函數傳入和再到處理數據出字段和函數供和組件使用類型的請求或者不需要將數

1.引入Route,createStore,combineReducers

const {Router, Route, Redirect, IndexRoute, browserHistory} = ReactRouter;
const {Provider, connect} = ReactRedux;
const { createStore, combineReducers, applyMiddleware, compose} = Redux;
const {syncHistoryWithStore, routerMiddleware, routerReducer, push } = ReactRouterRedux;
const thunkMiddleware = require("redux-thunk");

2.引入組件和reducer

const DanbaiPacket = require("Containers/DanbaiPacket");
const DanbaiPacket = require("Containers/DanbaiPacket");

3.綁定reducer,store

const reducer = combineReducers({
  routing: routerReducer,
  localizationReducer: LocalizationReducer,
  accountReducer: AccountReducer,
  notificationReducer: NotificationReducer,
  headlineDetailReducer: HeadlineDetailReducer,
  headlineEditorReducer: HeadlineEditorReducer,
  headlineListReducer: HeadlineListReducer,
  userCollectionsReducer: UserCollectionsReducer,
  userArticlesReducer: UserArticlesReducer,
  signInPopupReducer: SignInPopupReducer,
  notifyMessageReducer: NotifyMessageReducer,
  redPacketReducer: RedPacketReducer,
  danbaiPacketReducer: DanbaiPacketReducer
});

const middleware = routerMiddleware(browserHistory);
let initState = {};

let store = createStore(
    reducer,
    {},
    compose(
      applyMiddleware(thunkMiddleware, middleware),
      (window.RAILS_ENV === "development" && window.devToolsExtension) ? window.devToolsExtension() : f=>f
    )
);

4.Router結構

var routes = (
  
    
      
        
        
        
        
          
          
        
        
        
      
    
  
);

1.define這個組件
引入routerAction, connect做reducer連接
引入action中的函數getDanbaiPacket,dispatch到action中處理數據
this.props獲取reducer中的數據
組件上componentWillReceiveProps會受到reducer發來的數據,nextProps包含發來的信息.

define("Containers/DanbaiPacket", function(require, exports) {
  const { routerActions } = ReactRouterRedux;
  const { connect } = ReactRedux;
  const { getDanbaiPacket } = require("Actions/DanbaiPacketAction");

  var DanbaiPacket = React.createClass({
    getInitialState: function() {
      return {

      };
    },
    componentDidMount: function() {
      this.props.dispatch(getDanbaiPacket(this.props.params.id));
    },
    render: function() {
      const { localization, current_account, danbaiPacketDetail } = this.props;
      
      return (
        

          aaa
        
      );
    }
  });

  function mapStateToProps(state, ownProps) {
    return {
      localiztion: state.localizationReducer.languages[state.localizationReducer.languages.current],
      current_account: state.accountReducer.current_account,
      danbaiPacketDetail: state.danbaiPacketReducer.danbaiPacketDetail
    };
  }

  return connect(mapStateToProps)(connect(null, routerActions)(DanbaiPacket));
});

2.action
定義Action函數
定義type字段字符串
定義dispatch的函數,返回一個高階函數,傳入dispatch和getState,再dispatch到reducer處理數據
return出type字段和函數,供reducer和組件使用.
post類型的請求,或者不需要將數據掛載到reducer函數上的,不需要dispatch到reducer處理,直接用callback處理返回的數據.

//= require ../../util/fetch_posts
//= require ./notify_message_action

define("Actions/DanbaiPacketAction", function(require, exports) {
  const fetch = require("util/FetchPosts");
  const { addNotifyMesaage } = require("Actions/NotifyMessageAction");
  const INIT_DANBAI_PACKET = "INIT_DANBAI_PACKET";

  function initDanbaiPacket(data) {
    return {
      type: INIT_DANBAI_PACKET,
      data: data
    };
  }

  function getDanbaiPacket(id, callback) {
    return (dispatch, getState) => {
      fetch.get({
        url: "/api/events/" + id + ",json",
        dataType: "json",
        data: {
          sonkwo_client: "web"
        },
        success: function(res) {
          dispatch(initDanbaiPacket(res))
        },
        error: function(xhr) {
          if (xhr.status === 404) {
            dispatch(addNotifyMesaage("wufazhaodaoziyuan"));
          }
        }
      });
    }
  }

  return {
    INIT_DANBAI_PACKET,
    getDanbaiPacket
  }
});

3.reducer
從action引入type字符串
定義reducer函數,即可以在組件中被獲取的數據
每個reducer函數都會return出一個對象,這就是這個函數的值,要用Object.assign({}, state, action.data)
state的值會變化,直接action.data的話,那就只有這一個值.
可以用Object.assign({}, state, {rules: action.data}),
這樣掛載再reducer函數上的key為rules.
只要掛載再reducer函數上的key值有變化,只要有dispatch,就會觸發組件render
即使有兩個reducer處理函數,也是以dispatch為準,dispatch后會觸發reducer處理函數,觸發組件render.

//= require ../actions/danbai_packet_action

define("Reducers/DanbaiPacketReducer", function(require, exports) {
  const { INIT_DANBAI_PACKET } = require("Actions/RedPacketAction");
  const { combineReducers } = Redux;

  function danbaiPacketDetial(state={}, action) {
    switch (action.type) {
      case INIT_DANBAI_PACKET:
        return Object.assign({}, state, action.data);
      default:
        return state;
    }
  }

  return combineReducers({
    danbaiPacketDetial: danbaiPacketDetial
  });
});

4.子組件
define子組件
使用解構賦值,給rules初始值
也可以使用componentWillReceiveProps

define("Components/Example", function(require, exports) {
  var Example = React.createClass({
    getInitialState: function() {
      return {

      };
    },
    componentWillReceiveProps: function() {

    },
    componentDidMount: function() {

    },
    render: function() {
      const { rules = [] } = this.props;

      return (
        

          example
          {
            rules.map((item, index) => {
              return (
                

                  id: { item.id },
                  type: { item.type }
                
              )
            })
          }
        
      );
    }
  });

  return Example;
});

在父組件中引入,傳入danbaiPacketDetail.rules

1.所有請求都把數據掛在了reducer函數上,且都直接返回,造成數據雜糅,key值沖突,不易處理邏輯,
又造成重復render.
解決:

1.post請求或者不需要處理返回數據的,直接callback執行回掉,在action中不需要dispatch到reducer處理.
2.reducer處理數據時,return出來的值整個值,使用Object.assign({}, state, action.data),把數據
全部返回.

2.Modal的ErrorPopup只需要有一個,error為this.state.error,mode為"simple"則樣式自己寫.
層疊順序為:SignInPopup > ErrorPopup > 自身的modal
3.this.props.params.id,this.props.location.query只能在Route中的組件獲取.
4.對每個接口做錯誤處理.
5.對一些可能先返回undefined的值做保護,可以用解構賦值初始值.

const {a = []} = this.props;

6.post之后一般有回調,再重新dispatch獲取接口,或者直接在post接口中callbackc處理.
