我们的API工作正常,最近我们从
ServiceStack 4.5.14
到
ServiceStack.Core 1.0.44
使用强大的Kestrel http服务器。
框架引发异常,并由
AppHost.UncaughtExceptionHandlers
System.InvalidOperationException: StatusCode cannot be set because the response has already started.
at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.Frame.ThrowResponseAlreadyStartedException(String value)
at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http.Frame.set_StatusCode(Int32 value)
at ServiceStack.HttpExtensions.EndRequestWithNoContent(IResponse httpRes)
at ServiceStack.HttpResponseExtensionsInternal.WriteToResponse(IResponse httpRes, IRequest httpReq, Object result, Byte[] bodyPrefix, Byte[] bodySuffix, CancellationToken token)
at ServiceStack.Host.RestHandler.<>c__DisplayClass13_1.<ProcessRequestAsync>b__1(Object response)
at ServiceStack.AsyncExtensions.<>c__DisplayClass1_0`1.<ContinueClosure>b__0(Task innerTask)
-
此异常在我的方法返回后发生。它发生在框架代码中。
-
即使发生此错误,API仍能正确响应。
更新
:升级到ServiceStack后。核心v5.0.2,它仍然存在。但是stacktrace不同。
