1.接口返回的流和头部:

vue2.x  下载后台传过来的流文件(excel)后乱码问题-LMLPHP

vue2.x  下载后台传过来的流文件(excel)后乱码问题-LMLPHP

2.下载流文件的代码

vue2.x  下载后台传过来的流文件(excel)后乱码问题-LMLPHP

方法一:是用了插件 https://github.com/kennethjiang/js-file-download

方法二:是用了 blob

不管哪种方法,记得设置  responseType  !!!!!

附上代码:

//      导出订单
exportBill:function () { let url_post = Vue.prototype.api.apiList.EXPORT_BILL; let params_post = {
orderStartDate: this.timepickerDateFormat(this.rangeTime[]) || this.rangeTime[] || '',
orderEndDate: this.timepickerDateFormat(this.rangeTime[]) || this.rangeTime[] || '',
prodCode: this.prodId,
promoteFlag: this.promotionSiteId,
policyStatusList: this.tableBillStateCheckedData,
}; Vue.axios.post(url_post,params_post,{responseType: 'arraybuffer'}).then((res) => { let fileName = res.headers['content-disposition'].match(/fushun(\S*)xls/)[]; fileDownload(res.data,fileName); //如果用方法一 ,这里需要安装 npm install js-file-download --save ,然后引用 var fileDownload = require('js-file-download'),使用详情见github;
      // let blob = new Blob([res.data], {type: "application/vnd.ms-excel"});

      // let objectUrl = URL.createObjectURL(blob);

      // window.location.href = objectUrl;

    }).catch(function (res) {}); },
