1，封装axios实例 request.js

javascript">const axios = require('axios');// 创建一个axios实例
const service = axios.create({baseURL: "https://ip:port",timeout: 60000
});export default service

2，封装请求 api.js

javascript">import service from 'request'
import axios from "axios";export const canCancelApi = (data, cancel) => {return service({url: '/api/test',method: 'post',data,cancelToken: new axios.CancelToken((c) => {cancel && cancel(c)})})
}

3，调用api

javascript">import {onBeforeUnmount} from 'vue'
import {canCancelApi} from "api";const apiCancel = null
// 通过回调接收caccel方法
canCancelApi(params, (cancle) => {apiCancel = cancle}).then(res => {})onBeforeUnmount(() => {if(apiCancel){// 关闭页面时如果请求存在则取消请求apiCancel('custom-cancel')}
}
