DKAN API CSRF Validation Failed

Question

I'm trying to log into my DKAN instance via the API just through the terminal but I keep getting a CSRF validation failed error. Here's what I'm doing.

First I login an collect a CSRF token:

curl -X POST -i -H "Content-type: application/json" -H "Accept: application/json" -c cookies.txt -X POST http://192.168.33.10/?q=api/dataset/user/login -d '{
    "username":"admin",
    "password":"mypassword"
}'

This outputs the following:

HTTP/1.1 200 OK

Next I take the token from the above output and put it into the following command to log into DKAN and create a new dataset:

curl -X POST -i -H "Content-type: application/json" -H "X-CSRF-Token:Of5m-_2V9vwLYmI49aArgd6K9HSqVJwpQwSfQH1jlBU" -b cookies.txt -X POST http://192.168.33.10/?=api/dataset/node -d '{
    "title":"A node created via DKAN REST API",
    "type":"dataset",
    "body": {
        "und": [{"value": "This should be the description"}]
    }
}'

The output from this command is:

HTTP/1.1 403 Forbidden
Date: Mon, 24 Apr 2017 15:35:03 GMT
Server: Apache/2.4.18 (Ubuntu)
Expires: Sun, 19 Nov 1978 05:00:00 GMT

403 Access Denied: CSRF validation failed

I've just been following the API tutorial in the docs. Am I missing something?

Answer 1

I solved my own problem. Everything was correct apart from a missing space after the X-CSRF-TOKEN header in the second curl command.

The command should have been:

curl --request POST --include --header "Content-type: application/json" --header "X-CSRF-Token: Of5m-_2V9vwLYmI49aArgd6K9HSqVJwpQwSfQH1jlBU" --cookie cookies.txt --request POST http://192.168.33.10/?=api/dataset/node -data '{
    "title":"A node created via DKAN REST API",
    "type":"dataset",
    "body": {
        "und": [{"value": "This should be the description"}]
    }
}'

Notice the space between "X-CSRF-Token: and Of5m-_2V9vwLYmI49aArgd6K9HSqVJwpQwSfQH1jlBU". Evidently that's very important. I also changed the tags to their more readable form to help me understand what's going on.
