# store模块化开发 #

![在这里插入图片描述][20210122101342949.png]  
首先是文档结构：  
store文件夹默认的文件是index.js，这个文件相当于主入口文件：

## store中Index.js文件内容如下： ##

import Vue from "vue"
    import Vuex from "vuex"
    import cart from "./modules/cart.js"
    import shop from "./modules/shop.js"
    
    Vue.use(Vuex)
    const store = new Vuex.Store({ 
    	state:{ 
    		hasLogin:false,
    		userInfo:{ },
    		token:"',
    		openId:"",
    		path:"xxxxxx",
    		registerUrl:"xxxxxxxx"
    	},
    	getters:{ 
    		getOpenId(state){ 
    			return state.openId
    		}
    	},
    	mutations:{ 
    		setToken(state,payload){ 
    			state.token = payload;
    		}
    	},
    	actions:{ 
    		getData({ commit},payload){ 
    			commit("setToken",payload)
    		}
    	},
    	modules:{ 
    		cart,
    		shop
    	}
    })
    export default store

## modules下的cart.js文件 ##

const state = { 
    	updateCart:true,
    	cartCount:0
    }
    const getters = { 
    	getUpdateCart(state){ 
    		return state.updateCart
    	}
    }
    const mutations = { 
    	setUpdateCart(state,flag){ 
    		state.updateCart = Boolean(flag);
    	}
    }
    
    export default{ 
    	namespaced:true,
    	state,
    	getters,
    	mutations,
    	actions
    }

这个文件还可以写成下面的方式：

import Vue from "vue"
    import Vuex from "vuex"
    Vue.use(Vuex)
    const store = new Vuex.Store({ 
    	state:{ 
    		updateCart:true,
    		cartCount:0
    	},
    	getters:{ 
    		getUpdateCart(state){ 
    			return state.updateCart
    		}
    	},
    	mutations:{ 
    		setUpdateCart(state,payload){ 
    			state.updateCart = Boolean(payload)
    		}
    	},
    	actions:{ 
    	}
    })
    export default{ 
    	namespaced:true,
    	store
    }

## 调用modules中的函数方法 ##

`this.$store.commit("cart/setUpdateCart",true)`

调用函数的时候需要把模块的名称也加入到路径中，这样才可以调用到对应的函数。

## main.js文件内容 ##

import Vue from "vue"
    import store from "./store"
    import App from "./App"
    import request from "utils/request.js"
    
    import * as filters from "@/utils/filters"
    import { msg} from "@/utils/index.js"
    
    Vue.use(userLogin)
    Vue.prototype.$store = store; 这样就可以使用this.$store.state来调用store中的数据了
    Vue.prototype.$request = request
    
    const add = new Vue({ 
    	...App
    }).$mount()
    
    export default app

## request.js文件内容 ##

import store from "./store";
    import vue from "./main.js";
    import { API_BASE_URL} from "@/common/config.js";
    var lasttime = 0;
    var nowtime = 0;
    var auth = false;
    var timeId = null;
    
    function urlRequest(url,param,way,res,callBack){ 
    	uni.getNetworkType({ 
    		success:function(res){ 
    			if(res.networkType==='none'){ 
    				uni.navigateTo({ 
    					url:"/pages/public/noWifi"
    				})
    				return
    			}
    		}
    	})
    	let d = new Date();
    	let dval = 0;
    	let addVal = 0;
    	if(nowtime){ 
    		dval = d.getTime() - nowtime;
    		if(dval < 500){ 
    			addVal += dval;
    		}
    	}
    	if(!param.isWait && (dval > 1000 || addVal === 0)){ 
    		console.log("加载一次");
    	}
    	nowtime = d.getTime();//获取点击时间
    	let token = uni.getStorageSync('token') || "";
    	let openId = uni.getStorageSync("openId");
    	let dataParam = way=='POST'?JSON.stringify(Object.assign(param)):param;
    	let conType = "application/json";
    	if(param.contype == 'form'){ 
    		dataParam = param;
    		conType = "appliccation/x-www-form-urlencoded"
    	}
    	console.log("返回的openId",openId);
    	uni.request({ 
    		url:API_BASE_URL+url,
    		data:dataParam,
    		header:{ 
    			"ak":token,
    			"dk":dk,
    			"pk":"wbm",
    			"pt":"web",
    			"Accept":"application/json",
    			"Content-Type":conType
    		},
    		method:way,
    		success:(data)=>{ 
    			setTimeout(()=>{ 
    				uni.hideLoading();
    			},1500+addVal)
    			if(data.data.code===200){ 
    				res(data.data)
    			}else{ 
    				if(data.data.code===401){ 
    					console.log("接口出现401，跳转登录页面path:"+url);
    					let routes = getCurrentPages();
    					let curRoute = routes[routes.length - 1]
    					if(curRoute&&curRoute.route&&(curRoute.route ==='pages/public/login')){ 
    						return false
    					}
    					clearTimeOut(timeId);
    					timeId = setTimeout(()=>{

    						userAuth();
    					},300)
    				}
    			}else{
