当流调用循环大时，Grpc双向流被对等端终止？

Question

我在客户端(dart)和服务器(.net)之间有双向流。当客户端有大的流调用循环时，我遇到了问题。

在服务器上

System.IO.IOException: The request stream was aborted.
---> Microsoft.AspNetCore.Connections.ConnectionAbortedException: The HTTP/2 connection faulted.
  --- End of inner exception stack trace ---
  at System.IO.Pipelines.PipeCompletion.ThrowLatchedException()
  at System.IO.Pipelines.Pipe.GetReadResult(ReadResult& result)
  at System.IO.Pipelines.Pipe.GetReadAsyncResult()
  at Microsoft.AspNetCore.Server.Kestrel.Core.Internal.Http2.Http2MessageBody.ReadAsync(CancellationToken cancellationToken)
  at Grpc.AspNetCore.Server.Internal.PipeExtensions.ReadStreamMessageAsync[T](PipeReader input, HttpContextServerCallContext serverCallContext, Func`2 deserializer, CancellationToken cancellationToken)

在客户身上我得到了

gRPC Error (code: 2, codeName: UNKNOWN, message: HTTP/2 error: Stream error: Stream was terminated by peer (errorCode: 2)., details: null)

它的工作时，小流调用循环。

我试着增加MaxStreamsPerConnection，但仍然不起作用

.ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.ConfigureKestrel(serveroption => {
        
                        serveroption.Limits.Http2.MaxStreamsPerConnection = 5000;
                    }).UseStartup<Startup>();
                });

我的应用程序使用nginx作为反向代理。这是来自nginx webserver的问题。我从nginx得到的错误

客户端打算发送太大的块体:向上游发送请求时发送10489464字节，

要解决这个问题，只需添加

http {
    ...
    client_max_body_size 20M;
}   

Nginx error: client intended to send too large body
