在VUE中实现文件下载并判断状态的方法

 // Axios拦截请求并实现下载 import axios from 'axios' // download url export const downloadUrl = (url) => { console.log(url) let iframe = document.createElement('iframe') iframe.style.display = 'none' iframe.src = url iframe.onload = function () { document.body.removeChild(iframe) } document.body.appendChild(iframe) } // Add a response interceptor // res返回的东西可以跟后端确认 axios.interceptors.response.use(res => { if (res.data.status && res.data.status === 300) { return '300' // 链接正确，下载失败 } else { downloadUrl(res.request.responseURL) return '200' // 链接正确，下载成功 } }, error => { // Do something with response error return error // 链接错误 }) export default axios 

 import axios from './axiosExport' // 导出 或 下载 exportDoc () { let URL = `下载地址` let me = this axios.get(URL).then(function (response) { if (response === '200') { me.$message.success('下载成功！') } else { me.$message.warning('下载失败！') } }).catch(function (response) { console.log(response); }); }
