VUE下載文件，下載后台返回的response

Js文件中

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

request請求攔截處flask-filedown.js  

//在你axios 定義處 添加response返回類型
const service = axios.create({ responseType: 'blob', baseURL: "api", timeout: 15000 // request timeout
});

等你處理responese時候 

 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'); // 創建a標簽
      link.href = url; link.download = '切圖'; // 重命名文件
 link.click(); URL.revokeObjectURL(url); // 釋放內存
    }
