error in POST request with cURL on windows with rails

Question

I am having the following error when I try to use cURL to post a request on my localhost.

The request I am sending:

C:\Program Files (x86)\cURL\bin>curl -v -H "Content-type: application/json" -H "Accept: application/json" -X POST http://localhost:3000/users/sign_in -d '{"user": {"email":"email2@email.com", "password":"1234"}}'

and this is the error I am getting:

    *   Trying ::1...
* Connected to localhost (::1) port 3000 (#0)
> POST /users/sign_in HTTP/1.1
> Host: localhost:3000
> User-Agent: curl/7.46.0
> Content-type: application/json
> Accept: application/json

     localhost:3000
    </ADDRESS>
  </BODY>
</HTML>
* Closing connection 0

The problem is my GET requests work perfectly fine but POST requests are not working.

I tried using escape quotes:

C:\Program Files (x86)\cURL\bin>curl -v -H "Content-type: application/json" -H "Accept: application/json" -X POST http://localhost:3000/users/sign_in -d "{\"user\": \"{\"email\":\"email2@email.com\", \"password\":\"1234\"}\"}"

Beginning of the error:

    Note: Unnecessary use of -X or --request, POST is already inferred.
*   Trying ::1...
* Connected to localhost (::1) port 3000 (#0)
> POST /users/sign_in HTTP/1.1
> Host: localhost:3000
> User-Agent: curl/7.46.0
> Content-type: application/json
> Accept: application/json
> Content-Length: 7
>

I have been trying to solve the same issue for days now and I hate Windows so much. Any suggestions?

As suggested in a comment to an answer in this question, try avoid using single quote-marks and instead escaping the others like this: -d "{\"user\": \"....\"}"

Ooh, according the the curl-manual, the URL should be at the end of the parameters, not in the middle. Try that with the escaping. – ollpu May 05 '16 at 19:37
Thanks for your answers, tried that as well, same error – May 05 '16 at 19:41
That blob you pasted looks like the tail of a Rails error-message. The earlier parts might be indicating some other error. (That's not nice of Rails to just spit you an HTML-error message when you were asking for JSON) – ollpu May 05 '16 at 19:46
just added the beginning of the error. Not much to see there either – May 05 '16 at 21:17
The very beginning is just the things curl is printing. Can you paste the whole thing with something like pastebin? – ollpu May 05 '16 at 21:19
