VUE下载文件，下载后台返回的response

Js文件中

import request from "../utils/request-flask-filedown"; //切图下载
export function downloadMaps(params) { return request({ url: 'gh/cloud/dec/map/project/downloadMap', method: 'get', params }) }

request请求拦截处flask-filedown.js  

//在你axios 定义处 添加response返回类型
const service = axios.create({ responseType: 'blob', baseURL: "api", timeout: 15000 // request timeout
});

等你处理responese时候 

 const res = response.data; if (res!=null) { let blob = new Blob([res], { type: 'application/zip' }); let url = window.URL.createObjectURL(blob); const link = document.createElement('a'); // 创建a标签
      link.href = url; link.download = '切图'; // 重命名文件
 link.click(); URL.revokeObjectURL(url); // 释放内存
    }
