Ruby Net::HTTP - Stop automatically escaping quotes? - ruby-on-rails

Question

I have the following code:
http = Net::HTTP.new("www.something.com", 80)
http.set_debug_output($stdout)
http.post("/blah", "something", {'random-parameter' => 'value1="something",value2="somethingelse"'})
Then when I read the output from stdout, it looks like this:
<- "POST /blah HTTP/1.1\r\nAccept: */*\r\nContent-Type: application/x-www-form-urlencoded\r\nConnection: close\r\nrandom-parameter: value1=\"something\",value2=\"somethingelse\"\r\nContent-Length: 9\r\nHost: www.something.com\r\n\r\n"
<- "something"
with the quotes being escaped. The problem is that the slashes seem to be sent to the server, which doesn't like that. I'm getting an error that says
Unknown value for random-parameter in header: {value1=\\\"something\\\"value2=\\\"somethingelse\\\"}
So my question is, is there a way to tell Net::HTTP to not insert those slashes, or strip them out before sending the header?
Clarifications:
I'm using Ruby 1.8.7 with Rails 2.0.2.
I think it may be Rails that is escaping the characters, but I'm not sure how to make it stop.

Are you sure you're building up the header correctly? Net::HTTP does not quote quotes when sending the request. You can easily verify it by using for example netcat (nc):
Terminal 1:
> nc -v -l -p 2323
Terminal 2 (in irb):
> http = Net::HTTP.new("localhost", 2323)
> http.post("/blah", "something", {'random-parameter' => ... )
Result (in terminal 1):
listening on [any] 2323 ...
connect to [127.0.0.1] from localhost [127.0.0.1] 37598
POST /blah HTTP/1.1
Connection: close
Accept: */*
Random-Parameter: value1="something",value2="somethingelse"
Content-Type: application/x-www-form-urlencoded
Content-Length: 9
Host: localhost:2323
something
I think what you actually may want to do (not sure, but I'm guessing) is something more along the lines of the HTTP spec:
> http.post("/blah", "something", {
'random-parameter' => 'value1="something"; value2="somethingelse"' })
Rails is probably interpreting your first value1=... as the whole value..when you probably need to separate the values with ';', not ','.
Also note that you don't usually pass parameters through request headers. But maybe that's what you want to do in this case(?) Otherwise you should either pass the parameters in the URL itself like param1=foo&param2=bar, or use x-www-form-urlencoded to pass the parameters.

Answer 2

Isn't the problem that your name/value pairs are the value for "random-parameter", hence they need to be escaped.
I'd expect that when you inspect the random-parameter value in the controller method that it would not have the slashes - can you debug the code or print the parameter to see whats being received?
