How to send raw post data in a Rails functional test?

Question

I\'m looking to send raw post data (e.g. unparamaterized JSON) to one of my controllers for testing:

class LegacyOrderUpdateControllerTest < ActionControl         


        

Answer 1

I actually solved the same issues just adding one line before simulating the rspec post request. What you do is to populate the "RAW_POST_DATA". I tried to remove the attributes var on the post :create, but if I do so, it do not find the action.

Here my solution.

def do_create(attributes)
  request.env['RAW_POST_DATA'] = attributes.to_json
  post :create, attributes
end 

In the controller the code you need to read the JSON is something similar to this

  @property = Property.new(JSON.parse(request.body.read))

If you are using RSpec (>= 2.12.0) and writing Request specs, the module that is included is ActionDispatch::Integration::Runner. If you take a look at the source code you can notice that the post method calls process which accepts a rack_env parameter.

All this means that you can simply do the following in your spec:

#spec/requests/articles_spec.rb

post '/articles', {}, {'RAW_POST_DATA' => 'something'}

And in the controller:

#app/controllers/articles_controller.rb

def create
  puts request.body.read
end

I was searching very long for how to post raw JSON content in a integration test (Rails 5.1). I guess my solution could also help in this case. I looked up the documentation and source code for the post method: https://api.rubyonrails.org/v5.1/classes/ActionDispatch/Integration/RequestHelpers.html#method-i-post

This directed me to the process method for more details: https://api.rubyonrails.org/v5.1/classes/ActionDispatch/Integration/Session.html#method-i-process

Thanks to this, I finally found out what parameters are accepted by the process and thus post method. Here's what my final solution looked like:

post my_url, params: nil, headers: nil, env: {'RAW_POST_DATA' => my_body_content}, as: :json

Using Rails 4, I was looking to do this to test the processing of raw xml that was being posted to the controller. I was able to do it by just providing the string to the post:

raw_xml = File.read("my_raw.xml")
post :message, raw_xml, format: :xml

I believe if the parameter provided is a string, it just gets passed along to the controller as the body.

Answer 5

post :index, {:foo=> 'bar', :bool => 'true'}

Answer 6

In rails, 5.1 the following work for me when doing a delete request that needed data in the body:

delete your_app_url, as: :json, env: {
   "RAW_POST_DATA" =>  {"a_key" => "a_value"}.to_json
}

NOTE: This only works when doing an Integration test.
