1. axios拦截器进行配置，除了白名单中的接口，统统保存到全局变量canCancelAxios中

window.canCancelAxios = [];// http request 拦截器axios.interceptors.request.use(    config => {        let whiteList = ['/test1', '/test2']; // 白名单接口        if (config.url && whiteList.every(item => !config.url.includes(item))) {            config.cancelToken = new axios.CancelToken(function (c) { window.canCancelAxios.push({ key: config.key || "", cancel: c }) });        }        return config;    },    err => {        return Promise.reject(err);    })

2. 定义一个取消取消axios的方法

/** * 取消axios请求 * @param cellArr 要取消的接口；如果不传参，则取消canCancelAxios保存的所有接口 */export function cancelAxios(cellArr = []) {  if (cellArr.length > 0) {    cellArr.forEach(val => {      for (let i = 0; i < window.canCancelAxios.length; i++) {        if (window.canCancelAxios[i].key === val) {          window.canCancelAxios[i].cancel();          window.canCancelAxios.splice(i, 1);          i--;        }      }    })  } else {    for (let i = 0; i < window.canCancelAxios.length; i++) {      window.canCancelAxios[i].cancel();      window.canCancelAxios.splice(i, 1);      i--;    }  }}

3. 路由配置中，路由切换时，取消axios请求

import cancelAxios from "***";router.beforeEach((to, from, next) => {    cancelAxios();    // 进行其他业务操作})

4. 特殊情况下（比如切换tab页时），可能需要取消特定某些axios

import cancelAxios from "***";cancelAxios(["axios1", "axios2"]);

注意

// 这里取消特定的axios是根据axios拦截器中config.key来识别接口的，所以接口请求时要配置key参数，不然不能正确取消；// 比如上面要取消的["axios1", "axios2"]test1: () => Axios.get(`/path1`, { key: "axios1" }),test2: () => Axios.get(`/path2`, { key: "axios2" })
