关于axios的小知识

发请求1

axios({    method: 'GET',    //请求类型    url:'路径',    //设置请求路径    data:{    //设置请求体        title: "afafa"        author: "afafa"    }}).then(response => {    console.log(response);})

发请求2

axios.request({    method: 'GET',    url: '路径'}).then(response => {    console.log(response);})

发请求3

axios.post("路径" , {    "body": "afa"    //发送请求体    "postId": 2}).then(response => {    console.log(response);})

axios创建实例对象发送请求

const abc = axios.create({    baseURL: '路径',    timeout: 2000})

配置axios默认配置

axios.defaults.method = 'GET';axios.defaults.baseURL = '路径'axios.defaults.params = {id: 100};axios.defaults.timeout = 3000;

在发送请���时需要在请求头中添加 Authorization 字段携带 token，token 的值为 2b58f9a8-7d73-4a9c-b8a2-9f05d6e8e3c7。

（）

let t = axios.create({        headers: {            Authorization : `2b58f9a8-7d73-4a9c-b8a2-9f05d6e8e3c7`        }    })

原生JS发请求

var xhr = new XMLHttpRequest(); //创建发送请求的对象                    xhr.onreadystatechange = await function(){                        if(xhr.readyState === 4){                            console.log("服务器的响应结果已经全部收到")                            const obj = JSON.parse(xhr.responseText);                            console.log(obj)                        }                    }                    xhr.open("GET" , MockURL);                    xhr.send(null); 

async function fetchData() {                    try {                        const response = await fetch(MockURL);                        if (!response.ok) {                            throw new Error('Request failed');                        }                        const data = await response.json();                        console.log(data);                    } catch (error) {                        console.error(error);                    }                }

发送多个并发请求

function getUserAccount() {  return axios.get('/user/12345');}function getUserPermissions() {  return axios.get('/user/12345/permissions');}const [acct, perm] = await Promise.all([getUserAccount(), getUserPermissions()]);
