POST json to rails server

http, json, post, ruby, ruby-on-rails

Solution

If you are sending in the right headers, then you won't need to do "ActiveSupport::JSON.decode" -- rails will do that for you.

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

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

A 422 means Unprocessable Entity --- generally that there was a validation failure.

You should be able to have. If you can't, then your headers aren't set correctly.

def create
  if user = User.authenticate(params["email"], params["password"])
    session[:user_id] = user.id
    render :json => "{\"r\": \"t\"}" + req
  else
    render :json => "{\"r\": \"f\"}"
  end
end

Problem

``` def create req = ActiveSupport::JSON.decode(request.body) if user = User.authenticate(req["email"], req["password"]) session[:user_id] = user.id render :json => "{\"r\": \"t\"}" + req else render :json => "{\"r\": \"f\"}" end end ``` 'create' method is in a controller and mapped to "/login", I am setting correct content types and accept headers from my curl client. I am getting a 422 http status response all the time. Any suggestions?
