摘要：引入引入组件和绑定结构页面组件这个组件引入做连接引入中的函数到中处理数据获取中的数据组件上会受到发来的数据包含发来的信息定义函数定义字段字符串定义的函数返回一个高阶函数传入和再到处理数据出字段和函数供和组件使用类型的请求或者不需要将数

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.引入组件和reducer

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

3.绑定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结构

var routes = (
  
    
      
        
        
        
        
          
          
        
        
        
      
    
  
);

1.define这个组件
引入routerAction, connect做reducer连接
引入action中的函数getDanbaiPacket,dispatch到action中处理数据
this.props获取reducer中的数据
组件上componentWillReceiveProps会受到reducer发来的数据,nextProps包含发来的信息.

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
定义Action函数
定义type字段字符串
定义dispatch的函数,返回一个高阶函数,传入dispatch和getState,再dispatch到reducer处理数据
return出type字段和函数,供reducer和组件使用.
post类型的请求,或者不需要将数据挂载到reducer函数上的,不需要dispatch到reducer处理,直接用callback处理返回的数据.

//= 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
从action引入type字符串
定义reducer函数,即可以在组件中被获取的数据
每个reducer函数都会return出一个对象,这就是这个函数的值,要用Object.assign({}, state, action.data)
state的值会变化,直接action.data的话,那就只有这一个值.
可以用Object.assign({}, state, {rules: action.data}),
这样挂载再reducer函数上的key为rules.
只要挂载再reducer函数上的key值有变化,只要有dispatch,就会触发组件render
即使有两个reducer处理函数,也是以dispatch为准,dispatch后会触发reducer处理函数,触发组件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.子组件
define子组件
使用解构赋值,给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;
});

在父组件中引入,传入danbaiPacketDetail.rules

1.所有请求都把数据挂在了reducer函数上,且都直接返回,造成数据杂糅,key值冲突,不易处理逻辑,
又造成重复render.
解决:

1.post请求或者不需要处理返回数据的,直接callback执行回掉,在action中不需要dispatch到reducer处理.
2.reducer处理数据时,return出来的值整个值,使用Object.assign({}, state, action.data),把数据
全部返回.

2.Modal的ErrorPopup只需要有一个,error为this.state.error,mode为"simple"则样式自己写.
层叠顺序为:SignInPopup > ErrorPopup > 自身的modal
3.this.props.params.id,this.props.location.query只能在Route中的组件获取.
4.对每个接口做错误处理.
5.对一些可能先返回undefined的值做保护,可以用解构赋值初始值.

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

6.post之后一般有回调,再重新dispatch获取接口,或者直接在post接口中callbackc处理.
