From: Scott Archer Date: 2007-04-27T08:31:49+09:00 Subject: Re: Net::Http multiple parameters with the same name. I updated a method in http.rb It seems to have fixed the problem I was having. There may be a more elegant solution. I'd love for some criticism if someone wants to look at this. I'd also be interested in getting this code into the ruby distribution if it looks good. I'm new to ruby, and I don't know much about the process. # Set header fields and a body from HTML form data. # +params+ should be a Hash containing HTML form data. # Optional argument +sep+ means data record separator. # # This method also set Content-Type: header field to # application/x-www-form-urlencoded. def set_form_data(params, sep = '&') temp = [] params.map do |k,v| if(v.is_a? Array) for value in v temp << "#{urlencode(k.to_s)}=#{urlencode(value.to_s)}" end else temp << "#{urlencode(k.to_s)}=#{urlencode(v.to_s)}" end end self.body = temp.join(sep) #= params.map {|k,v| "#{urlencode(k.to_s)}=#{urlencode(v.to_s)}" }.join(sep) puts self.body self.content_type = 'application/x-www-form-urlencoded' end On 4/25/07, Scott Archer wrote: > I'm trying to use the Net::Http libraries to do a post request to a > java servlet. > I need to submit multiple parameters with the same name. > > test=1 > test=2 > test=3 > > if I were submitting the form in html it would look something like this. > > > > > > > This is the ruby code I am using currently. > > url = URI.parse("http://localhost/test/test.servlet") > req = Net::HTTP::Post.new(url.path) > req.set_form_data({'test'=>['1','2']}) > res = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) } > case res > when Net::HTTPSuccess, Net::HTTPRedirection > xml = res.body > else > res.error! > end > puts xml > > In the servlet I'm doing the following > String[] values = request.getParameterValues("test"); > This should return an array with the String values ["1","2","3"] > It's returning an array with one value ["123"] > > I know the java code is correct.
