问题描述

我们在 Azure 中有两个具有这种配置的环境（都位于西欧）：

测试：

阶段：

我们部署了相同的基于 Umbraco + uCommerce 的 Web 应用程序代码，但在 Stage 环境中的性能比在测试环境中要差得多。性能最差的是使用 uCommerce API 的页面。Umbraco 和 uCommerce 中的内容是相同的。后端处理时间在测试上小于 1 秒，在舞台上约为 20 秒。我们找不到这些环境之间的配置差异。我可能有什么问题？我们如何才能找到导致问题的原因？

编辑：

即使 AzureCDNToolkit:CdnUrl 值有效，Umbraco 日志也会显示大量此类错误：

2018-07-30 13:07:20,429 [P9292/D2/T31] ERROR Our.Umbraco.AzureCDNToolkit.UrlHelperRenderExtensions - Error resolving media url from the CDN System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.FixedSizeReader.ReadPacket(Byte[] buffer, Int32 offset, Int32 count) at System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Net.TlsStream.ProcessAuthentication(LazyAsyncResult result) at System.Net.TlsStream.Write(Byte[] buffer, Int32 offset, Int32 size) at System.Net.ConnectStream.WriteHeaders(Boolean async) --- End of inner exception stack trace --- at System.Net.HttpWebRequest.GetResponse() at Our.Umbraco.AzureCDNToolkit.UrlHelperRenderExtensions.<>c__DisplayClass6_1.b__0() at Our.Umbraco.AzureCDNToolkit.UrlHelperRenderExtensions.TryFiveTimes(Action delegateAction) at Our.Umbraco.AzureCDNToolkit.UrlHelperRenderExtensions.UrlToCdnUrl(String cropUrl, Boolean htmlEncode, String currentDomain)

编辑 一段时间后我发现了一个问题：Azure 使用 TLS 1.2 作为 Azure 服务的默认配置，因此为了使其正常工作，我所要做的就是在应用程序启动时添加这一行： ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
