c# - Pushsharp 支持 Apple Push Notification Authentication Key

Question

是否pushsharp支持新的 Apple approach使用 Apple Push Notification Authentication Key(永不过期)而不是使用证书发送 APN？有什么方法可以将它与 pushsharp 一起使用吗？如果没有，是否有任何其他 C# 库支持它？

Answer 1

你在这里:

private string GetToken()
{
    var algorithm = "ES256";
    var teamID = "teamID";
    var apnsKeyID = "apnsKeyID";
    var apnsAuthKeyPath = @"apnsAuthKeyPath";
    var epochNow = DateTimeOffset.Now.ToUnixTimeSeconds();

    var header = new Dictionary<string, object>()
    {
        { "alg", algorithm },
        { "kid" , apnsKeyID }
    };
    var payload = new Dictionary<string, object>()
    {
        { "iss", teamID },
        { "iat", epochNow }
    };

    var privateKey = GetPrivateKey(apnsAuthKeyPath);
    var token = Jose.JWT.Encode(payload, privateKey, algorithm: Jose.JwsAlgorithm.ES256, extraHeaders: header);
    return token;
}
private CngKey GetPrivateKey(string apnsAuthKey)
{
    using (var reader = File.OpenText(apnsAuthKey))
    {
        var ecPrivateKeyParameters = (ECPrivateKeyParameters)new PemReader(reader).ReadObject();
        var x = ecPrivateKeyParameters.Parameters.G.AffineXCoord.GetEncoded();
        var y = ecPrivateKeyParameters.Parameters.G.AffineYCoord.GetEncoded();
        var d = ecPrivateKeyParameters.D.ToByteArrayUnsigned();
        return EccKey.New(x, y, d);
    }
}

然后你可以简单地调用apns中的send方法。
