如何在轨道上的红宝石上使用卷曲？像这个

Just in case you don't know, it requires 'net/http'
以防万一你不知道，它需要'net/http'
require 'net/http'
uri = URI.parse("http://example.org")
# Shortcut
#response = Net::HTTP.post_form(uri, {"user[name]" => "testusername", "user[email]" => "[email protected]"})
# Full control
http = Net::HTTP.new(uri.host, uri.port)
request = Net::HTTP::Post.new(uri.request_uri)
request.set_form_data({"user[name]" => "testusername", "user[email]" => "[email protected]"})
response = http.request(request)
render :json => response.body
Hope it'll helps others.. :)

Here is a curl to ruby's net/http converter: https://jhawthorn.github.io/curl-to-ruby/
这是 ruby 的 net/http 转换器的 curl：https: //jhawthorn.github.io/curl-to-ruby/
For instance, a curl -v www.google.comcommand is equivalent in Ruby to:
例如，一个curl -v www.google.com命令在 Ruby 中等效于：
require 'net/http'
require 'uri'
uri = URI.parse("http://www.google.com")
response = Net::HTTP.get_response(uri)
# response.code
# response.body

The most basic example of what you are trying to do is to execute this with backticks like this
你正在尝试做的最基本的例子是用这样的反引号来执行它
`curl -d 'params1[name]=name¶ms2[email]' 'http://mydomain.com/file.json'`
However this returns a string, which you would have to parse if you wanted to know anything about the reply from the server.
但是，这将返回一个字符串，如果您想了解有关服务器回复的任何信息，则必须对其进行解析。
Depending on your situation I would recommend using Faraday. https://github.com/lostisland/faraday
根据您的情况，我建议使用法拉第。https://github.com/lostisland/faraday
The examples on the site are straight forward. Install the gem, require it, and do something like this:
网站上的例子很简单。安装 gem，需要它，然后执行如下操作：
conn = Faraday.new(:url => 'http://mydomain.com') do |faraday|
faraday.request :url_encoded # form-encode POST params
faraday.response :logger # log requests to STDOUT
faraday.adapter Faraday.default_adapter # make requests with Net::HTTP
end
conn.post '/file.json', { :params1 => {:name => 'name'}, :params2 => {:email => nil} }
The post body will automatically be turned into a url encoded form string. But you can just post a string as well.
帖子正文将自动转换为 url 编码的表单字符串。但是你也可以只发布一个字符串。
conn.post '/file.json', 'params1[name]=name¶ms2[email]'
