Re: Using net/HTTP - How to login and then retrieve data?

Yes, POST also requires basic_auth.

No, a cookie is not required.

For now I'd like to stick with using net/http, and possibly later look
at things like httpclient.

When I code according to your example (see below) I am still failing on
the SEARCH operation due to error <Net::HTTPPreconditionFailed 412
Precondition Failed-User not logged in. readbody=true>. This doesn't
make sense because I have successfully logged in, and I am re-using the
connection.

I appreciate your help Rob, because I didn't know how to re-use the
connection - Thanks!

Here's my current code:

require 'net/http'

url1 =
URI.parse('http://imls.rets.fnismls.com/rets/fnisrets.aspx/imls/login')
http = Net::HTTP.new(url1.host, url1.port)
http.read_timeout = 120
http.start do |connection|

  #LOGIN
  request1 = Net::HTTP::Post.new(url1.request_uri)
  request1.basic_auth 'myuser', 'mypass'
  request1.set_form_data({'RETS-Version' => 'RETS/1.7', 'Accept' =>
'*/*', 'User-Agent' => 'Mozilla/4.0'})
  #request1.body = 'something if needed'
  response1 = connection.request(request1)
  puts response1.body


  #SEARCH
  url2 =
URI.parse('http://imls.rets.fnismls.com/rets/fnisrets.aspx/imls/search')
  request2 = Net::HTTP::Post.new(url2.request_uri)
  request2.basic_auth 'myuser', 'mypass'
  request2.set_form_data({'RETS-Version' => 'RETS/1.7', 'Accept' =>
'*/*', 'User-Agent' => 'Mozilla/4.0',
  'SearchType' => 'Property',
  'Limit' => '15000',
  'Format' => 'COMPACT',
  'Query' =>
'%28L_UpdateDate%3D2011-01-03T23:49:57%2B%29,%28L_UpdateDate%3D2011-01-04T23:49:57%2D%29',
  'Class' => 'BC_4'
  })
  response2 = connection.request(request2)
  puts response2.inspect

  #LOGOUT
  url3 =
URI.parse('http://imls.rets.fnismls.com/rets/fnisrets.aspx/imls/logout')
  request3 = Net::HTTP::Post.new(url3.request_uri)
  request3.set_form_data({'RETS-Version' => 'RETS/1.7', 'Accept' =>
'*/*', 'User-Agent' => 'Mozilla/4.0'})
  request3.basic_auth 'myuser', 'mypass'
  response3 = connection.request(request3)
  puts response3.body
end
