This works on ruby 2.4 HTTPS Post with JSON object and the response body written out.

<pre><code>require 'net/http' #net/https does not have to be required anymore
require 'json'
require 'uri'

uri = URI('https://your.secure-url.com')
Net::HTTP.start(uri.host, uri.port, :use_ssl =&gt; uri.scheme == 'https') do |http|
 request = Net::HTTP::Post.new(uri, 'Content-Type' =&gt; 'application/json')
 request.body = {parameter: 'value'}.to_json
 response = http.request request # Net::HTTPResponse object
 puts "response #{response.body}"
end
</code></pre>

How do I send a JSON request in ruby? I have a JSON object but I dont think I can just do <code>.send</code>. Do I have to have javascript send the form?

Or can I use the net/http class in ruby?

With header - content type = json and body the json object?

Ruby send JSON request

身份验证

JSON

如何在ruby中发送JSON请求？我有一个JSON对象，但我想我不能只做.send。我必须让javascript发送表单吗？或者我可以使用ruby中的net/http类吗？使用header - content type = json和body作为json对象？
