最近在做blob流导出相关功能，其中需要导出excel、csv、word、zip压缩文件之类的，在导出excel和word中需要知道对应的content-type属性，正好看到下面这篇文章，感觉挺好的就记录一下
| 后缀 | MIME Type |
| .doc | application/msword |
| .docx | application/vnd.openxmlformats-officedocument.wordprocessingml.document |
| .xls | application/vnd.ms-excel |
| .xlsx | application/vnd.openxmlformats-officedocument.spreadsheetml.sheet |
| .ppt | application/vnd.ms-powerpoint |
| .pptx | application/vnd.openxmlformats-officedocument.presentationml.presentation |
附带导出excel文件格式的相关js代码
exportFile(data:any, fileName:string) { let blob = new Blob([data], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"});//以二进制形式存储，并转化为Excel let now = new Date(); let date = now.getFullYear() + ‘-‘ + (now.getMonth() +1) + ‘-‘ + now.getDate(); let exportFileName = date + ‘ ‘ + fileName + ".xlsx";//自定义导出excel表名称 saveAs(blob, exportFileName); //使用文件导出插件FileSaver.js }
