How to upload a file to the PC that the server gives?

Question

JavaScript

I am making a request to the server (sending a file). The server does something with this file and returns it in binary form. How can I assemble this file (binary), which has already come to the client, into .exe, so that the client downloads it to himself through the browser?

Answer 1

you have something wrong with the concepts .
the browser does not convert anything to "binary form". The file is already "binary".
the browser simply takes the file and sends it as is with a POST request to where you specified.
and if you receive a response from that server with bugs, this is already a problem with the response headers from that server. The browser needs to be told that it is downloading the file, not the text.
Well, the browser is not a compiler.
