How to invoke HTTP POST method over SSL in ruby?

Question

So here\'s the request using curl:

curl -XPOST -H content-type:application/json -d \"{\\\"credentials\\\":{\\\"username\\\":\\\"username\\\",\\\"key\\\":\\\"         


        

Answer 1

All others are too long here is a ONE LINER:

Net::HTTP.start('auth.api.rackspacecloud.com', :use_ssl => true).post(
      '/v1.1/auth', {:credentials => {:username => "username",:key => "key"}}.to_json,
      initheader={'Content-Type' => 'application/json'}
    )

* to_json needs require 'json'

---

OR if you want to

• NOT verify the hosts
• be more readable
• ensure the connection is closed once you're done

then:

ssl_opts={:use_ssl => true, :verify_mode => OpenSSL::SSL::VERIFY_NONE}
Net::HTTP.start('auth.api.rackspacecloud.com', ssl_opts) { |secure_connection|
  secure_connection.post(
      '/v1.1/auth', {:credentials => {:username => "username",:key => "key"}}.to_json,
      initheader={'Content-Type' => 'application/json'}
    )
}

In case it's tough to remember what params go where:

• SSL options are per connection so you specify them while opening the connection.
• You can reuse the connection for multiple REST calls to same base url. Think of thread safety of course.
• Header is a "request header" and hence specified per request. I.e. in calls to get/post/patch/....
• HTTP.start(): Creates a new Net::HTTP object, then additionally opens the TCP connection and HTTP session.
• HTTP.new(): Creates a new Net::HTTP object without opening a TCP connection or HTTP session.
