vue http请求 vue-resource使用方法

import http from 'vue-resource'

// 基于全局Vue对象使用http
Vue.http.get('/someUrl', [options]).then(successCallback, errorCallback);
Vue.http.post('/someUrl', [body], [options]).then(successCallback, errorCallback);// 在一个Vue实例内使用$http
this.$http.get('/someUrl', [options]).then(successCallback, errorCallback);
this.$http.post('/someUrl', [body], [options]).then(successCallback, errorCallback);

import Vue from 'vue'
import Vuex from 'vuex'Vue.use(Vuex)// 定义初始值
const state = {
isShowLoading: false
}// 获取变量值
const getters = {
isShowLoading: state => state.isShowLoading
}//定义触发状态对象方法,传入state整个对象
//在页面中触发时使用this.$store.commit('mutationName') 触发Mutations方法改变state的值
const mutations = {
setLoadingType(state, type) {
state.isShowLoading = type;
}
}//异步执行方法，传入参数context，等同于整个store
//处理Mutations中已经写好的方法 其直接触发方式是 this.$store.dispatch(actionName)
const actions = {
setLoadingType({commit}, type) {
// 调用mutations 方法
commit('setLoadingType', type)
}
}export default new Vuex.Store({
state,
mutations,
actions,
getters
})

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
