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-b8a2-9f05d6e8e3c

（）

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()]);
