Bash script example for custom services action with session authentication

Here is Bash script example how to work with custom services action that requires session authentication.

Endpoint requirements :

• Set "Authentication" as "Session authentication"
• Set "Request parsing" to "application/x-www-form-urlencoded"

##
# Configurations.
##

# Base URL of your web site.
site_url="http://example.com"

# Endpoint URL for login action.
login_url="$site_url/service/path/user/login"

# Drupal authentication credentials.
password="YOURPASS"
username="YOURNAME"

# Path to temporary file which will store your cookie data.
cookie_path=/tmp/cookie

# URL of your custom action.
action_url="$site_url/service/path/custom/action"

# This is data that you want to send to your custom endpoint.
data="name=Alex&hobby=Drupal"

##
# Logic. Most likely you shouldn't change here anything.
##

# Get token and construct the cookie, save the returned token.
token=$(curl -b $cookie_path -c $cookie_path --request GET "$site_url/services/session/token" -s)

# Authentication. POST to $login_url with the token in header "X-CSRF-Token: $token".
curl -H "X-CSRF-Token: $token" -b $cookie_path -c $cookie_path -d "username=$username&password=$password" "$login_url" -s

# Get new token after authentication.
token=$(curl -b $cookie_path -c $cookie_path --request GET "$site_url/services/session/token" -s)

# Send POST to you custom action URL. With the token in header "X-CSRF-Token: $token"
curl -H "X-CSRF-Token: $token" -b $cookie_path -c $cookie_path -d "$data" "$action_url" -s
