Subscription error - "Invalid raw ECDSA P-256 public key." #95

MkLHX · 2021-03-16T16:40:31Z

Hello!
I'm facing issue about subscription step.
On Firefox

Subscription error. 
Arguments

0: DOMException: Invalid raw ECDSA P-256 public key.

On chrome

Subscription error. Arguments [DOMException: Failed to execute 'subscribe' on 'PushManager': The provided applicationServerKey is …, callee: ƒ, Symbol(Symbol.iterator): ƒ]

I generate vapid keys by using python package py-vapid==1.7.1

by using command vapid --gen for public and private keys
my settings.py contains:

INSTALLED_APPS = [
 # /../
     'webpush',
 # /../
]
privk = (
    open(os.path.join(BASE_DIR, "private_key.pem"), "r+")
    .read()
    .strip()
    .split("\n")[1:][:-1]
)
WEBPUSH_VAPID_PRIVATE_KEY = "".join(privk)
pubk = (
    open(os.path.join(BASE_DIR, "public_key.pem"), "r+")
    .read()
    .strip()
    .split("\n")[1:][:-1]
)
WEBPUSH_VAPID_PUBLIC_KEY = "".join(pubk)
WEBPUSH_SETTINGS = {
    "VAPID_PUBLIC_KEY": WEBPUSH_VAPID_PUBLIC_KEY,
    "VAPID_PRIVATE_KEY": WEBPUSH_VAPID_PRIVATE_KEY,
    "VAPID_ADMIN_EMAIL": "[email protected]",
}

I wrote a view to render django template tags:

from django.views.decorators.http import require_http_methods
from django.shortcuts import render, redirect


@require_http_methods(["GET"])
def index(request):
    webpush = {
        "group": "my_group"
    }  # The group_name should be the name you would define.

    return render(request, "push_notification/index.html", {"webpush": webpush})

my template:

{% extends "gui/base.html" %}

{% load webpush_notifications %}

{% block head %}
    <!-- # For django templating engine -->
    {% webpush_header %}
{% endblock %}

{% block body %}
<p> Hello World! </p>
<!-- # For django templating engine -->
{% webpush_button %}
{% endblock %}

in browser:
firefox

chrome

My public key is:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEONKLXu1hkjwHIYxgERnucAfOjunh
h7ZGtgxNi7kXUU/+jyhHeC6YkTSzpwIkn2q6ibguVmJL5j9BriKgaqst1Q==
-----END PUBLIC KEY-----

My private key is:

in the template:

<!DOCTYPE html>
<html lang="en">

Ok i find the good way.

In the documentation we have to put public vapid key in settings.

But when i do this i'm facing issue, when i use vapid --applicationServerKey instead that works!

So i think there is a misunderstand in the doc about private key, public key and server key....

@MkLHX Thanks. It would be nice if you can update the documentation

MkLHX · 2021-03-21T11:30:58Z

@safwanrahman yeah why not, but the true question is this is normal you wrote the code with public key use and today i can use it only with the server key?

Maybe i doing mistake.

I'm ok to PR but if do it, for me we have to change every variable name about vapid_public_key to vapid_public_server_key.
