使用 firestore 对 C# 桌面应用程序进行身份验证

我已经准备好了使用 firestore 数据库的桌面应用程序，为了访问它，我使用了 GOOGLE_APPLICATION_CREDENTIALS。根据文档，我无法引入此类身份验证的规则，但我想这样做。我已向支持人员发送问题，并被告知使用 REST API。这是我的问题？是否可以通过 REST API 进行身份验证，但读取和写入数据仍使用 Google.Cloud.Firestore nuget ？这个怎么做 ？请记住，我有用 c# WPF 编写的桌面应用程序。也许您知道我的问题的其他解决方案？

感谢您的反馈弗兰克，在您的链接中我找到了答案。要从桌面应用程序对 firestore 进行身份验证，您需要执行以下操作：

public FirestoreDb CreateFirestoreDbWithEmailAuthentication(string emailAddress, 
string password, string firebaseApiKey, string firebaseProjectId)
{
            // Create a custom authentication mechanism for Email/Password authentication
            // If the authentication is successful, we will get back the current authentication token and the refresh token
            // The authentication expires every hour, so we need to use the obtained refresh token to obtain a new authentication token as the previous one expires
            var authProvider = new FirebaseAuthProvider(new FirebaseConfig(firebaseApiKey));
            var auth = authProvider.SignInWithEmailAndPasswordAsync(emailAddress, password).Result;
            var callCredentials = CallCredentials.FromInterceptor(async (context, metadata) =>
            {
                if (auth.IsExpired()) auth = await auth.GetFreshAuthAsync();
                if (string.IsNullOrEmpty(auth.FirebaseToken)) return;

                metadata.Clear();
                metadata.Add("authorization", $"Bearer {auth.FirebaseToken}");
            });
            var credentials = ChannelCredentials.Create(new SslCredentials(), callCredentials);

            // Create a custom Firestore Client using custom credentials
            var grpcChannel = new Channel("firestore.googleapis.com", credentials);
            var grcpClient = new Firestore.FirestoreClient(grpcChannel);
            var firestoreClient = new FirestoreClientImpl(grcpClient, FirestoreSettings.GetDefault());

            return FirestoreDb.Create(firebaseProjectId, null, firestoreClient);
}

当然，首先您需要在 firestore 控制台中添加电子邮件用户。
