azure - Azure 中的 Blazor : The list of component records is not valid

Question

将 blazor 应用程序部署到 azure 时，五分之四会因以下错误而失败(从 chrome 开发工具复制):

[2019-12-16T11:12:55.214Z] Information: Normalizing '_blazor' to 'https://example.com/_blazor'.
[2019-12-16T11:12:55.470Z] Information: WebSocket connected to wss://example-web-signalr-service.service.signalr.net/client/?hub=componenthub&asrs.op=%2F_blazor&negotiateVersion=1&asrs_request_id=...&id=...&access_token=...

我们无法理解这一点。 blazor 失败的原因可能是什么？为什么它在我们本地开发人员的机器上没有失败？在谷歌中很难找到任何关于此的信息。

请告诉我是否需要提供更多信息。我不确定哪些代码片段可能是有用的信息。

试试这个:

services.AddSignalR().AddAzureSignalR(options =>
{
    options.ServerStickyMode = Microsoft.Azure.SignalR.ServerStickyMode.Required;
});
