vue axios使用,axios的封装

一.了解vue axios,vue-resource?     axios与vue-resource类似于 jQuery的$ajax, 用来处理请求与响应。    vue2.0之后,就不再对vue-resource更新,而是推荐使用axios,这里不过多介绍,感兴趣的可以去 https://github.com/pagekit/vue-resource   axios是基于Promise 用于浏览器和node.js的http客户端, axios主要是用于向后台发起请求的,还有在请求中做更多是可控功能。 二.安装和简单使用axios npm install -save axios vue-axios    在入口文件main.js下引用,然后挂在原型下 。 ps: axios不是插件,所以不能通过Vue.use() 进行注册 import Vue from 'vue' Vue.prototype.$_axios = axios // 组件中使用 this.$_axios.get(url).then((res) => {})   vue-axios 是按照vue插件的方式去写的,是为了符合规范,方便协作。 import Vue from 'vue' import axios from 'axios' import VueAxios from 'vue-axios' Vue.use

问题 I'm getting an infinite loop with this code. I've been trying some of the solutions from another posts but they don't work. locationAddress is an array of addresses and I'm trying to get the coordinates using the Google Maps Geocode API. const reducer = (state, action) => { switch (action.type) { case 'add': return [ ...state, { address: action.address, name: action.name, id: action.id } ]; case 'remove': return state.filter((_, index) => index !== action.index) default: return state; } }

问题 I am trying to present a simple user list from an API which returns this: [{"UserID":2,"FirstName":"User2"},{"UserID":1,"FirstName":"User1"}] I do not understand fully how to handle Axios responses with types. The Typescript error is Type '{} | { id: number; firstName: string; }' is not assignable to type 'IntrinsicAttributes & UserListProps & { children?: ReactNode; }'. Property 'items' is missing in type '{}' but required in type 'UserListProps'. from the <UserList /> element in the Users

基于Vue + axios + WebApi + NPOI导出Excel文件

不羁的心 提交于 2021-02-13 17:47:22
一、前言 项目中前端采用的Element UI 框架, 远程数据请求,使用的是axios,后端接口框架采用的asp.net webapi,数据导出成Excel采用NPOI组件。其业务场景,主要是列表页(如会员信息,订单信息等)表格数据导出,如表格数据进行了条件筛选,则需要将条件传至后端api,筛选数据后,导出成Excel。 思考过前端导出的3种方案: 1.使用location.href 打开接口地址.缺点: 不能传token至后端api, 无法保证接口的安全性校验,并且接口只能是get方式请求. 2.采用axios请求接口,先在筛选后的数据服务端生成文件并保存,然后返回远程文件地址,再采用 location.href打开文件地址进行下载. 缺点: 实现复杂,并且每次导出会在服务端生成文件,但是又没有合适的时机再次触发删除文件,会在服务端形成垃圾数据。优点:每次导出都可以有记录。 3. 采用axios请求接口,服务端api返回文件流,前端接收到文件流后,采用blob对象存储,并创建成url, 使用a标签下载. 优点:前端可传token参数校验接口安全性,并支持get或post两种方式。 因其应用场景是导出Excel文件之前,必须筛选数据,并需要对接口安全进行校验,所以第3种方案为最佳选择。在百度之后,发现目前使用最多的也是第3种方案。 二、Vue + axios 前端处理 1
