使用blob二进制流的方式下载后台文件
//url请求地址,datas传给后台的参数,fileName文件名,format文件类型后缀名如.xls
downLoadFile(url,datas,fileName,format){
this.http.post(url, datas, { responseType: 'blob' }).subscribe((result:any)=>{
const link = document.createElement('a');
const blob = new Blob([result], { type: 'application/zip' }); link.setAttribute('href', window.URL.createObjectURL(blob)); link.setAttribute('download', fileName + format); link.style.visibility = 'hidden'; document.body.appendChild(link); link.click(); document.body.removeChild(link);
}) };
注:本实例在angular6框架下实现
