Using the RestClient gem, I need to create a request such as the following:
GET http://host/path?p=1&p=2
What is the proper syntax to accomplish this? Note that the receiving host is not Rails.
Tried:
resource = RestClient::Resource.new( 'http://host/path' )
params = { p: '1', p: '2' }
# ^ Overrides param to have value of 2 (?p=2)
params = { p: ['1','2'] }
# ^ results in 'p[]=abc&p[]=cde' (array [] indicators not wanted)
resource.get( { params: params } )
You can pass the parameters in as a string:
resource.get(params: 'p=1&p=2')
For instance, using the restclient shell:
>> RestClient.log = Logger.new(STDOUT)
#<Logger:0x007fa444cbecc0 @progname=nil, @level=0, @default_formatter=#<Logger::Formatter:0x007fa444cbec70 @datetime_format=nil>, @formatter=nil, @logdev=#<Logger::LogDevice:0x007fa444cbebd0 @shift_size=nil, @shift_age=nil, @filename=nil, @dev=#<IO:<STDOUT>>, @mutex=#<Logger::LogDevice::LogDeviceMutex:0x007fa444cbeba8 @mon_owner=nil, @mon_count=0, @mon_mutex=#<Mutex:0x007fa444cbeb58>>>>
>> resource = RestClient::Resource.new( 'http://www.example.net' )
#<RestClient::Resource:0x007fa444c9fdc0 @url="http://www.example.net", @block=nil, @options={}>
>> resource.get(params: 'p=1&p=2')
RestClient.get "http://www.example.net", "Accept"=>"*/*; q=0.5, application/xml", "Accept-Encoding"=>"gzip, deflate", "Params"=>"p=1&p=2"
# => 200 OK | text/html 1270 bytes

If you don't want to write code to build a string, which you should avoid because it's not necessarily straightforward, let Ruby's URI class cobble it together:
require 'uri'
URI::encode_www_form([['p', 1], ['p', 2]])
# => "p=1&p=2"
Discovered this issue for RestClient : https://github.com/rest-client/rest-client/issues/59 so it seems that it can't be done 'natively' through params.
My solution was to modify the URL, using:
query_params = "?p=1&p=2"
resource[query_params].get
