出版到Azure后,Azure Signalr Service 403
我最近开始使用 signalR 尝试 .Net Core 6 Blazor 服务器聊天应用程序。我能够让示例应用程序在本地运行。然而,使用已发布的 Azure 应用服务将应用迁移到 Azure SignalR 服务一直很困难。
我一直收到 403 禁止结果。
我没有找到太多使用 .net core 6 和 SignalR 服务的教程。我欢迎您提供一步一步的链接!

builder.Services.AddRazorPages();

builder.Services.AddSignalR().AddAzureSignalR();
builder.Services.AddResponseCompression(opts =>

opts.MimeTypes = ResponseCompressionDefaults.MimeTypes.Concat(
new[] { "application/octet-stream" });
});
var app = builder.Build();
app.UseResponseCompression();
// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
app.UseExceptionHandler("/Error");
// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
app.UseHsts();
}

hubConnection.On<string, string>("ReceiveMessage", (user, message) =>
{
var encodedMsg = $"{user}: {message}";
messages.Add(encodedMsg);

});
await hubConnection.StartAsync();
}

{
if (hubConnection is not null)
{
await hubConnection.SendAsync("SendMessage", userInput, messageInput);
}
}
public bool IsConnected =>
hubConnection?.State == HubConnectionState.Connected;
public async ValueTask DisposeAsync()
{
if (hubConnection is not null)
{
await hubConnection.DisposeAsync();
}
}
}
这是错误: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1] 执行请求时发生未处理的异常。 System.Net.Http.HttpRequestException:响应状态代码不指示成功:403(禁止)。
我不确定我可以提供哪些其他信息有助于解决此问题。
I've recently started experimenting with the .Net Core 6 Blazor server chat app using signalR. I was able to get the sample app to work locally. However, migrating the app to Azure SignalR service with a published Azure app service has been a struggle.
I'm consistently getting 403 forbidden results.
I have not found much in the way of tutorials for using .net core 6 AND SignalR service. I'd welcome a link to a step-by-step!

Here is the error:
Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1]
An unhandled exception has occurred while executing the request.
System.Net.Http.HttpRequestException: Response status code does not indicate success: 403 (Forbidden).
I'm not sure what other information I could provide that would be helpful to troubleshoot this.

我想您需要从应用程序服务配置中启用 Web 套接字功能。
I guess you need to On web socket features from App Service configuration.
事实证明,问题与身份验证有关。我的应用服务已启用身份验证,但我已发布的应用程序目前尚未使用身份验证。我在应用程序服务设置中关闭了(目前)的身份验证,然后重新发布。它现在正在工作。
Turns out the issue was related to Authentication. My App Service had Authentication enabled but my Published app is not using authentication at the moment. I turned off Authentication (for now) in the App Service settings and re-published. It is working now.
