问题描述
我已经用C#编写了Windows服务，该服务连接到Firebase数据库并存储数据.对于连接和数据库通信，我使用了StepUp Labs，Inc.的NuGet软件包，分别名为"FirebaseAuthentification.net"和"FirebaseDatabase.net".
I have written a Windows service in C# which connects to the Firebase Database and stores data. For connection and database communication, I use a NuGet Packages called "FirebaseAuthentification.net" and "FirebaseDatabase.net", both by StepUp Labs, Inc.
在我的测试系统上，一切正常.在客户的系统上，存在防火墙/procy限制，拒绝通信.我们已经打开了端口443，可以发送请求，但是答案没有到达.
On my test system, everything works fine. On the customer's system, there are firewall/procy restrictions which deny communication. We already opened Port 443 and are able to send a request, but the answer does not arrive.
旧版GCM文档说:
但是消息不是数据库身份验证.我在firebase文档或网络中的其他任何地方都找不到任何内容.
But Messaging is not Database Authentification. I did not find anything in the firebase docs or anywhere else in the net.
为了使连接"正常工作，我必须打开哪些端口?
Which Ports do I have to open in order to make the Connection work?
推荐答案
Firebase身份验证和Firebase实时数据库都使用HTTPS在客户端和服务器之间进行通信.这意味着所有通信都通过端口443.
Firebase Authentication and the Firebase Realtime Database both use HTTPS to communicate between the client and the server. This means that all communication goes over port 443.
在可能的情况下，数据库通信在端口443上使用Web套接字.您可能要检查防火墙是否做了一些专门阻止Web套接字的操作.
The database communication uses web sockets over port 443 when possible. You might want to check if the firewall does something to specifically block web sockets.
