Inproper encoding of [] and nil in query params

[kikonen-fiksu]

For example, following params

{
  foo: [1, 2],
  bar: nil
}

Expected encoding for these is:

"foo[]=1&foo[]=2&bar"

However, HTTPClient encodes it as

"foo=2&bar="

Notice lost value and "=" after bar.

Partial workaround in Rails env seems to be "params.to_query", which is still, however not dealing null case approriately.

I.e. That null case causes nasty inconsistency between json and query encoding
