Receiving POST data in Rails 4 and reading request.body

Question

I want to send a POST request to a rails application and have it save and parse the request body in the database...

My route on the receiving end is currently setup as:

post '/request' => 'controller#receives_data'

when I post data to this controller I use:

def post_it
  connection.post(uri.path, "this is data", header_with_authkey)
end

My controller method that receives the post is setup as:

def receives_data
   log(request.body.read)
end

However I am getting a 422 error, unprocessable entity, and the log file is always empty...

Are there specific headers I need to include to post this to a rails app? Are there specific configurations I need to include in my controller or routes?

Solution 1

You'll need to set the following headers in your post.

Content-Type: application/json
Accept: application/json

Solution 2

request.raw_post

Read the request body. This is useful for web services that need to work with raw requests directly.

What content type are you using in your request?

The only header I specify is my authorization token.

Does the Net::HTTP post method always send the data as JSON data?

You should set Content-Type: header field for POST. If no Content-Type: field given, this method uses “application/x-www-form-urlencoded” by default. Read here -> ruby-doc.org/stdlib-2.0.0/libdoc/net/http/rdoc/Net/…

If that doesn't work, it could alternatively be due to this bug -> github.com/rails/rails/issues/11402. Check the version you are using.
