那些遇到过的问题

SignalR 与 Azure 的连接不起作用（.net core 3.1）

Fre*_*ens 3 azure signalr .net-core

我正在尝试将我的应用程序与Azure SignalR 连接，但似乎没有建立连接。

当我在基本配置文件中使用并在本地运行程序时，一切正常：

services.AddSignalR();
Run Code Online (Sandbox Code Playgroud)

但是当我像这样将其更改为Azure时（我在这里硬编码了密钥）

services.AddSignalR().AddAzureSignalR("Endpoint=https://frenscoservice.service.signalr.net;AccessKey=<MYKEY>;Version=1.0;");
Run Code Online (Sandbox Code Playgroud)

我在客户端收到错误消息

“无法加载资源：服务器响应状态为 500（内部服务器错误）”

和

“错误：无法完成与服务器的协商：错误：内部服务器错误”

我设法获得了下面的完整服务器日志文件。任何指针将不胜感激。我仍然可以选择默认运行 SignalR，而不使用 Azure，但我对 SignalR 进行了数千次调用，Azure 似乎解释说使用他们的服务会更快。

这发生在我的冲刺审核当天，当时我们达到了免费套餐 Azure SignalR 服务的最大消息计数。正如您在日志中看到的，您重新设置了 20k 消息限制。

您只需创建一项新的免费 Azure SignalR 服务并更改新服务或升级的密钥即可。在我们的开发过程中，我们只是在它几乎完成之前创建了新的，并将其更改为标准层。
