1.1、什么是Axios？

Axios是专注于网络数据请求的库。相比于原生的XML HttpRequest对象，axios 更简单易用，相比于jQuery，axios 更加轻量化，只专注于网络数据请求

1.2、Axios发送GET请求

具体语法：axios.get(url[, config])

<button type="button" class="btn btn-primary">GET请求button>

<script>
    document.querySelector("button").addEventListener("click", () => {
        axios.get("http://localhost:8088/api/getUser", { params: { name: "晓琳", age: 22 } }).then(resp => {
            console.log(resp.data)	
        })
    })
script>

详细配置参考官方文档

1.3、Axios发送POST请求

具体语法：axios.post(url[, data[, config]])

<button type="button" class="btn btn-info">POST请求button>

<script>
    document.querySelector("button").addEventListener("click", () => {
        axios.post("http://localhost:8088/api/addUser", { name: "小白", age: 25 }).then(resp => {
            console.log(resp.data)
        })
    })
script>

1.4、Axios发送请求

具体语法：`axios({

​ url: “请求URL地址”,

​ method: “请求方式”,

​ data: { /* POST数据 */ },

​ params: { /* GET参数 */ }

​ }).then(callback)`

<button type="button" class="btn btn-warning">Axiosbutton>

<script>
    document.querySelector("button").addEventListener("click", () => {
        axios({
            url: "http://localhost:8088/api/addUser",
            method: "POST",
            data: { 
                name: "小赵", 
                age: 23 
            },
        }).then(resp => {
            console.log(resp.data)
        })
    })
script>

1.5、默认配置

<script>
    // 基本路径
    axios.defaults.baseURL = 'http://localhost:8088'
    // 超时时间
    axios.defaults.timeout = 3000

    document.querySelector("button").addEventListener("click", () => {
        axios({
            url: "/api/addUser",
            method: "POST",
            data: {
                address: "河南",
                location: "洛阳市"
            },
            // 请求头
            headers: { 'token': 'ASK' },
            // 文件上传处理进度事件
            onUploadProgress: function (e) {
                // console.log(e)
                if (e.event.lengthComputable) {
                    // ...
                }
            }
        }).then(resp => {
            console.log(resp.data)
        })
    })
script>
