c# - Unity+Firebase-数据库[错误] WebSocket : ws_0 - could not connect

Question

我似乎无法找到解决此错误的有效解决方案，更完整:

018-06-01 10:33:09 PM [Error] WebSocket: ws_0 - could not connect System.Net.Sockets.SocketException (0x80004005): No route to host

2018-06-01 10:33:09 PM [Error] WebSocket: ws_0 - WebSocketException during handshake Firebase.Database.Internal.TubeSock.WebSocketException: unknown host: ########.firebaseio.com ---> System.Net.Sockets.SocketException: No route to host

注意，以上错误每秒重复几次，ws_#每次递增1

统一 2018.1.1f1

Firebase-Database:最新的，几天前得到的

一段代码:

void Start() {
    FirebaseApp.LogLevel = LogLevel.Verbose;
    FirebaseDatabase.DefaultInstance.LogLevel = LogLevel.Verbose; // Or your database instance, if not using the default.

    FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
        var dependencyStatus = task.Result;
        if (dependencyStatus == Firebase.DependencyStatus.Available) {
            FirebaseApp app = FirebaseApp.DefaultInstance;
            // NOTE: You'll need to replace this url with your Firebase App's database
            // path in order for the database connection to work correctly in editor.
            app.SetEditorDatabaseUrl("https://########.firebaseio.com/");
            if (app.Options.DatabaseUrl != null) app.SetEditorDatabaseUrl(app.Options.DatabaseUrl);
        } else {
            Debug.LogError(System.String.Format(
                "Could not resolve all Firebase dependencies: {0}", dependencyStatus));
            // Firebase Unity SDK is not safe to use here.
        }
    });
}

下面是我尝试访问firebase数据库

DatabaseReference mDatabaseRef = FirebaseDatabase.DefaultInstance.RootReference;
staticLocalData.thisUser = new UserData();
staticLocalData.thisUser.userID = newUser.UserId;
staticLocalData.thisUser.email = email;
staticLocalData.thisUser.firstName = firstName;
staticLocalData.thisUser.lastName = lastName;
registerData temp = new registerData();
temp.firstName = firstName;
temp.lastName = lastName;
temp.email = email;
temp.userName = userName;

Debug.Log(JsonUtility.ToJson(temp));
mDatabaseRef.Child("users").SetValueAsync("saddsa:23");  
//mDatabaseRef.Child("users").Child(newUser.UserId).SetRawJsonValueAsync(JsonUtility.ToJson(temp));

规则集:(应该允许所有)

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

补充说明:

• 使用了 Firebase 身份验证并且运行良好，我只是无法操作/访问数据库
• 一直以此作为我的主要引用资料: https://firebase.google.com/docs/database/unity/save-data
• 使用净 3x 和 4x，结果相同
• 也是单声道

Answer 1

使用:

OSX Sierra 10.12.6 上的 Unity 编辑器 2018.2.5f1

脚本运行时 4.x

脚本后端 IL2CPP

API 级别 4.x

Firebase 插件版本 5.2.1

发生了完全相同的问题。这似乎与 Mono Websocket 实现有关，正如在以下问题上更详细地讨论的那样:

https://github.com/firebase/quickstart-unity/issues/106

https://github.com/firebase/quickstart-unity/issues/162

Firebase 开发团队通过为每个平台提供他们自己的 native websocket 实现来绕过那里描述的内容。显然，Unity Editor 的实现落后了。

此处解决此问题的方法是为编辑器平台禁用 ../Firebase/Plugins/Mono/下的 FirebaseDatabase.dll，然后直接在 ../Firebase/Plugins/下启用一个 FirebaseDatabase.dll .

到目前为止，还不错。
