I plan to use JSON data in both request and response in my project and having some problems in testing.
After searching for a while, I find the following code which uses curl
to post JSON data:
curl -H "Content-Type:application/json" -H "Accept:application/json" \
-d '{ "foo" : "bar" }' localhost:3000/api/new
In the controller I can access the JSON data simply using params[:foo]
which is really easy. But for functional testing, I only find post
and xhr
(alias for xml_http_request
).
How can I write functional test in rails to achieve the same effect as using curl
? Or should I do test in other ways?
Here's what I've tried. I find the implementation for xhr
in action_controller/test_case.rb
, and tried to add jhr
method simply changing 'Conetent-Type' and 'HTTP_ACCEPT'. (Added in test/test_helpers.rb
.)
def json_http_request(request_method, action, parameters = nil, session = nil, flash = nil)
@request.env['Content-Type'] = 'Application/json'
@request.env['HTTP_ACCEPT'] ||= [Mime::JSON, Mime::JS, Mime::HTML, Mime::XML, 'text/xml', Mime::ALL].join(', ')
__send__(request_method, action, parameters, session, flash).tap do
@request.env.delete 'Content-Type'
@request.env.delete 'HTTP_ACCEPT'
end
end
alias jhr :json_http_request
I used this in the same way as xhr
, but it does not work. I inspected the @response
object and sees the body is " "
.
I also find one similar question on Stack Overflow but it's for rails 2 and the answer for posting raw data does not work in rails 3.
As of Rails 5, the way to do this is:
post new_widget_url, as: :json, params: { foo: "bar" }
This will also set the Content-type
header correctly (to application/json
).
I found that this does exactly what I want – post JSON to a controller's action.
post :create, {:format => 'json', :user => { :email => "[email protected]", :password => "foobar"}}
