使用RestClient gem，我需要创建一个如下请求：
GET http://host/path?p=1&p=2
完成此操作的正确语法是什么？请注意，接收主机不是Rails。
尝试过：
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 } )
您可以将参数作为字符串传递：
resource.get(params: 'p=1&p=2')
例如，使用restclient外壳：
>> 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

如果您不想编写代码来构建字符串，应该避免使用它，因为它不一定很简单，让Ruby的URI类将其拼凑起来：
require 'uri'
URI::encode_www_form([['p', 1], ['p', 2]])
# => "p=1&p=2"
