A mixture of Damien’s response and your example number 2 worked for me. I used a simple login page to test, I expect that your registration view is similar. Damien’s response almost works, but is missing the sessionid cookie.

I recommend a more robust approach. Rather than manually entering the cookies from other requests, try using curl’s built in cookie management system to simulate a complete user interaction. That way, you reduce the chance of making an error:

$ curl -v -c cookies.txt -b cookies.txt host.com/registrations/register/
$ curl -v -c cookies.txt -b cookies.txt -d "email=user@site.com&a=1&csrfmiddlewaretoken=<token from cookies.txt>" host.com/registrations/register/

The first curl simulates the user first arriving at the page with a GET request, and all the necessary cookies are saved. The second curl simulates filling in the form fields and sending them as a POST. Note that you have to include the csrfmiddlewaretoken field in the POST data, as suggested by Damien.

Try:

curl
 -d "email=test@test.com&a=1"
 http://127.0.0.1:8083/registrations/register/

Notice especially the format of the -d argument.

However, this probably won’t work, as your view likely needs a POST request instead of a GET request. Since it will be modifying data, not just returning information.

CSRF protection is only required for ‘unsafe’ requests (POST, PUT, DELETE). It works by checking the ‘csrftoken’ cookie against either the ‘csrfmiddlewaretoken’ form field or the ‘X-CSRFToken’ http header.

So:

curl
 -X POST
 -d "email=test@test.com&a=1&csrfmiddlewaretoken={inserttoken}"
 --cookie "csrftoken=[as above]"
 http://127.0.0.1:8083/registrations/register/

It’s also possible to use --header "X-CSRFToken: {token}" instead of including it in the form data.

I worked with curl like this

• You have to submit csrftoken in header as X-CSRFToken.
• You have to submit form data in JSON format.
  Demo,

First we will fetch csrf_token & store in cookie.txt (or cookie.jar as they call it)

$ curl -c cookie.txt http://localhost.com:8000/ 

cookie.txt content

# Netscape HTTP Cookie File
# http://curl.haxx.se/docs/http-cookies.html
# This file was generated by libcurl! Edit at your own risk.
localhost.com  FALSE   /   FALSE   1463117016  csrftoken   vGpifQR12BxT07moOohREGmuKp8HjxaE

Next we resend the username, password in json format. (you may send it in normal way). Check the json data escape.

$curl --cookie cookie.txt http://localhost.com:8000/login/   -H "Content-Type: application/json" -H "X-CSRFToken: vGpifQR12BxT07moOohREGmuKp8HjxaE" -X POST -d "{\"username\":\"username\",\"password\":\"password\"}" 
{"status": "success", "response_msg": "/"}
$

you can store the returns new csrf_token session cookie in same file or new file (I have stored in same file using option -c.)

$curl --cookie cookie.txt http://localhost.com:8000/login/   -H "Content-Type: application/json" -H "X-CSRFToken: kVgzzB6MJk1RtlVnyzegEiUs5Fo3VRqF" -X POST -d "{\"username\":\"username\",\"password\":\"password\"}" -c cookie.txt

-Content of cookie.txt

# Netscape HTTP Cookie File
# http://curl.haxx.se/docs/http-cookies.html
# This file was generated by libcurl! Edit at your own risk.

localhost.com  FALSE   /   FALSE   1463117016  csrftoken   vGpifQR12BxT07moOohREGmuKp8HjxaE
#HttpOnly_localhost.com    FALSE   /   FALSE   1432877016  sessionid   cg4ooly1f4kkd0ifb6sm9p

When you store new csrf_token & session id cookie in cookie.txt, you can use same cookie.txt across the website.

You am reading cookies from previous request from cookie.txt (–cookie) and writing new cookies from response in same cookie.txt (-c).

Reading & submitting form now works with csrf_token & session id.

$curl --cookie cookie.txt http://localhost.com:8000/home/

Here is how i did it, using the rest framework tutorial

open a browser e.g. chrome then pressing F12 open the developer tab and monitor the Network, login using your user credentials and get your CRSF token from monitoring the POST

then in curl execute:

curl http://127.0.0.1:8000/snippets/ \
 -X POST \
 -H "Content-Type: application/json" \
 -H "Accept: text/html,application/json" \
 -H "X-CSRFToken: the_token_value" \
 -H "Cookie: csrftoken=the_token_value" \
 -u your_user_name:your_password \
 -d '{"title": "first cookie post","code": "print hello world"}' 

I think its cleaner to not put the token in the body but rather the header using X-CSRFToken

curl-auth-csrf is a Python-based open-source tool capable of doing this for you: “Python tool that mimics cURL, but performs a login and handles any Cross-Site Request Forgery (CSRF) tokens. Useful for scraping HTML normally only accessible when logged in.”

This would be your syntax:

echo -n YourPasswordHere | ./curl-auth-csrf.py -i http://127.0.0.1:8083/registrations/register/ -d 'email=test@test.com&a=1' http://127.0.0.1:8083/registrations/register/

This will pass along the POST data as listed, but also to include the password passed via stdin. I assume that the page you visit after “login” is the same page.

Full disclosure: I’m the author of curl-auth-csrf.

To make the Curl–Django communication work, I had to provide

• the CSRF token in the X-CSRFToken header field;
• the CSRF token in the Cookie header field;
• the session identifier in the Cookie header field.
