blob格式導出文件

最近在作blob流導出相關功能，其中須要導出excel、csv、word、zip壓縮文件之類的，在導出excel和word中須要知道對應的content-type屬性，正好看到下面這篇文章，感受挺好的就記錄一下

 

後綴	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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

附帶導出excel文件格式的相關js代碼

 exportFile(data:any, fileName:string) {
    let blob = new Blob([data], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"});//以二進制形式存儲，並轉化爲Excel
    let now = new Date();
    let date = now.getFullYear() + '-' + (now.getMonth() +1) + '-' + now.getDate();
    let exportFileName = date + ' ' + fileName + ".xlsx";//自定義導出excel表名稱
    saveAs(blob, exportFileName); //使用文件導出插件FileSaver.js
  }
