Is there any way to modify multipart form-data field

[AmolM27]

I am currently trying to implement a proxy that modifies field 'filename' and relay that in the proxy request. Formidable is perfect to retreive the value of the field via: form.on('field', function(field, value) { //receive form fields here console.log(field.filename) }) However, can it be updated to take another another value rather than just reading it?

Question unclear.

The fields object can be changed after the .parse callback.

How are you relaying the request ?

So here is code example. I basically want to change the field value to be 'test1.docx' for example. The 'filename' field is set to: 81_105_115_116_54_46_100_111_99_120. I will need to change that from ascii to string before relaying the request. This field is part of the multipart form data. To put some context I mean that field 'name="filename"\r\n' + '\r\n' + to change if that is making sense?

var app = require('express')(); const { createProxyMiddleware } = require('http-proxy-middleware'); var formidable = require('formidable')

const filter = function (pathname, req) {

var form = new formidable.IncomingForm();
form.on('field', function(field, value) {
    //receive form fields here
    value = 'test1.docx'
    return value;
})
return true;

};

app.use('*', createProxyMiddleware(filter, { target: "", changeOrigin: true, })).listen(10008);

I don't know about createProxyMiddleware, try again on stack overflow maybe
