Can I do it here?

我可以在这里做吗？

No, for security reasons you have no control of this on the client. You can rename the file on the server when it gets uploaded.

不，出于安全原因，您无法控制客户端。您可以在上传文件时重命名服务器上的文件。

for security reasons you cannot do such thing i.e. manipulate multipart file or file to be uploaded do that on server

出于安全原因，您不能这样做，即操作多部分文件或要上传的文件在服务器上执行此操作

I know the question is old but if anyone is still struggling with similar problem, please try to use append()or set()method of the FormData.

我知道这个问题很老，但如果有人仍在为类似的问题苦苦挣扎，请尝试使用FormData 的append()或set()方法。
