Authentication failling on Firefox and Chrome

[gcmestre]

Hey,

Thank you for the work on this lib.

I'm currently not able to post push notifications to firefox and chrome as the example shows. Both give me authentication error.

Settings:

chrome_demo = {
    "subscription_info": {
        "endpoint": "https://fcm.googleapis.com/fcm/senddSbTwHYXBxQ:APA91bFjU7L9Vs09sDCJc_H5QhuZqASMTrW7jYUM70xahdJ1Bj8tDPSJDlOd_2_MeyWJbgLK1dmOxvGmovX2t-JUqR7Va7MT4XugEQk_mzhQw1Ko8l3wRpUAyImbSVeD8kVfxfK-cDe0",
        "expirationTime": None,
        "keys": {
            "p256dh": "BGOQdDEJw-7M7Cpa56qiqNau9U00gB3Ik-jSeAdm0WRwpBeS6qUXJhaJ7cTPkjj7qRYI0cS2KEy1OSia6S-By1k",
            "auth": "Ehjdbe-3rFnHW9p92Mvkjg"
        }
    },
    "headers": {
        "TTL": "60",
        "Content-Length": "0",
        "Authorization": "vapid t=eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJhdWQiOiJodHRwczovL2ZjbS5nb29nbGVhcGlzLmNvbSIsImV4cCI6MTYwMTc4NjM5MSwic3ViIjoibWFpbHRvOnNpbXBsZS1wdXNoLWRlbW9AZ2F1bnRmYWNlLmNvLnVrIn0.5Djt0lsmwIJhvf7Mx5aw8gIwgJGBzP23LTAP8f_DCO_sWDFXD4dYn6ZkpLgudxtGJWOT5pz86D6mQpHXa9iofQ, k=BDd3_hVL9fZi9Ybo2UUzA284WG5FZR30_95YeZJsiApwXKpNcF1rRPF3foIiBHXRdJI2Qhumhf6_LFTeZaNndIo",
    }
}

Call:

   webpush(
        subscription_info=subscription_info,
        data=data,
        vapid_private_key=vapid_private_key,
        verbose=True,
        #vapid_claims={"sub": "mailto:YourNameHere@example.com"},
        headers=headers
    )`

The results are:

`Sending request to
        host: https://fcm.googleapis.com/fcm/send/dSbTwHYXBxQ:APA91bFjU7L9Vs09sDCJc_H5QhuZqASMTrW7jYUM70xahdJ1Bj8tDPSJDlOd_2_MeyWJbgLK1dmOxvGmovX2t-JUqR7Va7MT4XugEQk_mzhQw1Ko8l3wRpUAyImbSVeD8kVfxfK-cDe0
        headers: {'ttl': '60', 'content-length': '0', 'authorization': 'vapid t=eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJhdWQiOiJodHRwczovL2ZjbS5nb29nbGVhcGlzLmNvbSIsImV4cCI6MTYwMTc4NjM5MSwic3ViIjoibWFpbHRvOnNpbXBsZS1wdXNoLWRlbW9AZ2F1bnRmYWNlLmNvLnVrIn0.5Djt0lsmwIJhvf7Mx5aw8gIwgJGBzP23LTAP8f_DCO_sWDFXD4dYn6ZkpLgudxtGJWOT5pz86D6mQpHXa9iofQ, k=BDd3_hVL9fZi9Ybo2UUzA284WG5FZR30_95YeZJsiApwXKpNcF1rRPF3foIiBHXRdJI2Qhumhf6_LFTeZaNndIo', 'content-encoding': 'aes128gcm'}

And it works, I receive the notification.

But if I use the vapid_claims sub and the headers are generated by the lib I get an authentication error as seen bellow.

Call:

   webpush(
        subscription_info=subscription_info,
        data=data,
        vapid_private_key=vapid_private_key,

        vapid_claims={"sub": "mailto:YourNameHere@example.com"},
    )`

On Firefox I have a similar.

I used this site to test https://gauntface.github.io/simple-push-demo/.

Am I doing something wrong? Why am I getting the authorization field wrong?

Thank you for the support.
