无论我尝试什么，我似乎都无法获得推送通知......
这是错误代码。
{"code":401,"errno":109,"error":"Unauthorized","message":"InvalidSignature","more_info":"http://autopush.readthedocs.io/en/latest/http.html#error-codes"}该问题似乎与密钥不匹配或无效签名有关。

我正在生成公钥/私钥：
function base64url_encode($data) {
return rtrim(strtr(base64_encode($data), '+/', '-_'), '=');
}
function generateVapidKeys(){
if(file_exists('vapid.json')){
$vapidKeys = json_decode(file_get_contents('vapid.json'));
return base64url_encode(hex2bin('04'.$vapidKeys->x.$vapidKeys->y));
}else{
$keyPair = openssl_pkey_new([
'digest_alg' => 'sha256',
'private_key_type' => OPENSSL_KEYTYPE_EC,
'curve_name' => 'prime256v1', // P-256 curve
]);
}
$privateKeyDetails = openssl_pkey_get_details($keyPair);
$x = str_pad(bin2hex($privateKeyDetails['ec']['x']), 64, '0', STR_PAD_LEFT);
$y = str_pad(bin2hex($privateKeyDetails['ec']['y']), 64, '0', STR_PAD_LEFT);
$d = str_pad(bin2hex($privateKeyDetails['ec']['d']), 64, '0', STR_PAD_LEFT);
file_put_contents('vapid.json', json_encode([
'x' => $x,
'y' => $y,
'd' => $d,
], JSON_PRETTY_PRINT));
return base64url_encode(hex2bin('04'.$x.$y));
}
$publicKey = generateVapidKeys();

你的程序是错误的。
为了让推送 API 正常工作，我们应该这么做。
