---

A decorator that handles CSRF protection.

On a GET request, a CSRF token is generated and stored in the session key specified by the session_key parameter.

On a POST request, the form_key specified is checked against the session_key specified.

• If they match, the request is allowed to continue.

• If no match, the response will be abort(abort_code), default 401.

@bp.route("/admin", methods=["GET", "POST"])
@include_csrf(session_key="csrf", form_key="csrf")
def admin_page():
    ...
    # You must pass in the CSRF token from the session into the template.
    # Then add <input type="hidden" name="csrf" value="{{ csrf }}"> to the form.
    return render_template("admin.html", csrf=session.get("csrf"))

Form key:

<input type="hidden" name="csrf" value="{{ csrf }}">
