Access value of an array sent to node/express server

Let me start by saying I am a total newbie/hack. The answer is probably very easy... I apologize in advance.

I am sending an object via jquery $.ajax (POST) to a Node.js server running express. The object looks something like this on my server before I make the Ajax call:

var data = {
  "to" : "[email protected]",
  "attachment" : [{"file": "somefile.jpg"}, {"file": "someOtherFile.jpg"}]
}

This is the call to my server:

$.ajax({
    type: "POST",
    url: "http://myHostHere.com",
    data: data,
    success: function(data){
      console.log("Success... Returned Data: " + data);
    }
});

On my Node server here is the route that accepts the request:

app.post('/send/', urlEncodeParser, function(req, res){
        console.log("Req Body: " + JSON.stringify(req.body));
      });

The urlEncodeParser middleware refers to this code:

let urlEncodeParser = bodyParser.urlencoded({ extended:false });

My receiving Node server receives the object and I can easily get the value of "to" via req.body.to no problem... For some reason I can't figure out how to access the 'file' values though. When I console.log the req.body on my Node server I see now that my object looks different.

Specifically I call console.log(JSON.stringify(req.body))

The output to the console looks like this:

"to" : "[email protected]",
"attachment[0][file]" : "somefile.jpg",
"attachment[1][file]" : "someOtherFile.jpg"

I cannot figure out how to access the value of attachment[0][file] in my code. I have tried req.body.attachment[0].file and req.body.attachment[0][file] and req.body.attachment[0]['file'] each time I get an error TypeError: Cannot read property '0' of undefined

Also I try to just console.log("attachment: " + req.body.attachment) and I get attachment: undefined.

Any help is much appreciated!

You can access the value using the bracket notation:

req.body['attachment[0][file]']

More importantly though is that you find out why your request payload looks like that... Unfortunately you did not provide any information how you send the request...
