c# – 从Firebase数据库加载需要身份验证的数据抛出错误firebase
我有一个网站,它利用Azure上的SQL Server来获取所有数据.我正在与另一家公司合作,为我的数据库中存在的特定记录获取额外的补充信息.
当正在查看这些“特定记录”时,我想提供另一个链接以从Firebase数据库中检索该补充信息. 所以,我正在尝试编写一个可以检索这些数据的服务,这就是我迄今为止所写的PoC: private readonly string firebaseUrl = "https://{myproject}.firebaseio.com/"; private readonly string authToken = "x:xxxxxxxxxxx:xxx:xxxxxxxxxxxxxxxx"; public async Task<IEnumerable<InMatchStat>> GetInMatchStats() { try { var firebase = new FirebaseClient(firebaseUrl,new FirebaSEOptions { AuthTokenAsyncFactory = () => Task.FromResult(authToken) }); var stats = await firebase.Child("my/collection/path").OnceAsync<InMatchStat>(); if (stats == null || !stats.Any()) { return null; } return await Convert(stats.AsEnumerable()); } catch (Exception exception) { var message = exception.ToString(); } return null; } 这是我在尝试执行var stats = await firebase.Child()…. call时从Firebase返回的错误:
这是FirebaseDatabase.NET Github页面的链接:https://github.com/step-up-labs/firebase-database-dotnet 如果链接在将来失效,这里是我正在尝试复制的确切示例,该示例显示在该站点上: var auth = "ABCDE"; // your app secret var firebaseClient = new FirebaseClient( "<URL>",new FirebaSEOptions { AuthTokenAsyncFactory = () => Task.FromResult(auth) }); 以及该页面的查询示例: var firebase = new FirebaseClient("https://dinosaur-facts.firebaseio.com/"); var dinos = await firebase .Child("dinosaurs") .OrderByKey() .StartAt("pterodactyl") .LimitToFirst(2) .OnceAsync<Dinosaur>(); foreach (var dino in dinos) { Console.WriteLine($"{dino.Key} is {dino.Object.Height}m high."); } 我的实施在哪里出错了? 解决方法
只是想让这个更新,因为我终于想出了解决方案,对我来说……
这是我从中获得解决方案的地方:https://github.com/step-up-labs/firebase-database-dotnet/issues/60 此版本传递电子邮件地址和密码以获取身份验证令牌.然后,一旦我们拥有令牌,就会像以前一样将其传递给Firebase客户端. (注意:我需要添加FirebaseAuthentication.net nuget包) public async Task<IEnumerable<InMatchStat>> GetInMatchStats() { const string firebaseUrl = "https://xxxxxxxxxxxxxx.firebaseio.com/"; const string firebaseUsername = "xxxxxxxxxxxxxxxxxxxxx@xxxxx.xxx"; const string firebasePassword = "xxxxxxxx"; const string firebaseApiKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; bool tryAgain = false; FirebaseAuthLink token = null; try { var auth = new FirebaseAuthProvider(new FirebaseConfig(firebaseApiKey)); do { try { token = await auth.SignInWithEmailAndPasswordAsync(firebaseUsername,firebasePassword); } catch (FirebaseAuthException faException) { // checking for a false tryAgain because we don't want to try and create the account twice if (faException.Reason.ToString() == "UnknownEmailAddress" && !tryAgain) { // create,then signin token = await auth.CreateUserWithEmailAndPasswordAsync(firebaseUsername,firebasePassword,"Greg",false); tryAgain = true; } throw; } catch (Exception) { throw; } } while (tryAgain); var firebase = new FirebaseClient(firebaseUrl,new FirebaSEOptions { AuthTokenAsyncFactory = () => Task.FromResult(token.FirebaseToken) }); var stats = await firebase.Child("my/collection/path").OnceAsync<InMatchStat>(); if (stats == null || !stats.Any()) { return null; } //return await Convert(stats.AsEnumerable()); } catch (Exception exception) { var message = exception.ToString(); } return null; } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
