Excelファイルをaxiosで扱うときのメモ

Last updated at Posted at 2018-09-10

ハマったポイント

サーバ処理

return c.Blob(http.StatusOK, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", buf.Bytes())

上記のレスポンスをaxiosでExcelデータとして取得し,処理する時

axios.get('/ex').then(res=>{
    let blob = new Blob([res.data]);
     ....
});

これだと,ファイルは文字化けしてしまう.

ミス

axios.getはデフォルトが一度文字列として,処理する.

解決策

getでファイルタイプを選択しておく.

axios.get('/ex',{
    responseType:'blob',
    dataType:'binary',
}).then(res=>{
    let blob = new Blob([res.data]);
     ....
});
