在img标签中显示blob（javascript）

Question

I'm getting a blob file from mySql and It looks like the image below.

and I'd like to show this image through <img src={imagefile}/> (I'm using React.js).

How can I the blob file to url link? I tried URL.createObjectURL(imagefile)

but It gives me an error that Failed to execute 'createObjectURL' on 'URL': No function was found that matched the signature provided

please Help ToT

你需要使用下面的代码将数据转换为base64，然后使用可以在你的img标签中使用Base64 <img src =“yourbase64here”/>

let base64String = btoa(String.fromCharCode(...new Uint8Array(data)));
