would you not be better providing the input as a hash?

params = { :param_one => 'foo', :param_two => 'bar' } def hash_to_params hsh hsh.map { |k, v| "#{k}=#{v}" }.join '&' end

Rails has a Hash#to_param-method

{ :param_one => 'foo', :param_two => 'bar' }.to_param

This refactoring does not provide the leading '&' for the query. You can decide whether that's better to prepend to the last line of the method or append in the line that calls it.

Finally I choose arvanasse variant but without creating array.
I think, it isn't necessary

def array_to_params(param_name, params) # normalize to an array first params = [params] unless params.is_a?(Array) param_string = "" params.each_with_index{|item, idx| params << "&#{param_name}[#{idx}]=#{item}" } param_string end http = Net::HTTP.new(uri.host, uri.port) response = http.post(path, "user=test_user" + array_to_params)
I need to post some array using ruby.
It should be like: &data[0]=blahblah1&data[1]=blahblah2
UPD:
I have requirement for POST parameters. I can not change parameters names.
In fact, I have to post on several pages.
On first page I need to post with parameters named "data" (data[0]... data[n]).
On second page I need to post with parameters named "ids" (ids[0]... ids[n]).
and so on.
