Rspec-rails: Unable to POST raw request body

[ademars94]

Here's a snippet from my spec:

foo = "some raw data"
post "/foo", foo

I am getting an ArgumentError, despite the Relish docs saying this is ok.

Could reproduce

require 'rails_helper'

RSpec.describe "logout", type: :controller do
  it "removes the cookie" do
    foo = "some raw data"
    post "/logout", foo
  end
end

(master versions of all rspec repos, latest rails, both controller and request specs)

This is reproducible back to at least RSpec 3.5

Also @request.env['RAW_POST_DATA'] = 'some raw data' did not work.
After the POST request, the ENV 'RAW_POST_DATA' is empty

Here is some snippet:
In Spec file:
@request.env['RAW_POST_DATA'] = 'some raw data'
post :some_action

In Rails Controller:
request.body.read => "" # should be 'some raw data'

It is braking with Rails 5.2.1

For reference, I'm using body in the post like so to set the RAW_POST_DATA.

 post :event, body: params.to_json

This is coming from ActionPack in the process which powers post etc: https://github.com/rails/rails/blob/v5.2.2/actionpack/lib/action_controller/test_case.rb#L477-L479

    Failure/Error: post '/rewards', headers: {}, body: str, format: :text

     ArgumentError:
       unknown keywords: body, format

what it's?

[OpakAlex]

use params: str without headers.

If you pass json then it consider as raw body and if you pass hash then it consider as params.

post :event, params.to_json

I think this issue solves it, or at least it did for me -> https://github.com/rspec/rspec-rails/issues/1650

This depends on your rails versions and is no longer in the docs, closing for now
