有什么方法可以处理 HttpClient java 中的 HTTP/2 Goaway 收到的 IOException？

Question

I am making API calls in the application, At some point randomly it throws java.io.IOException: /149.222.1.1:553232: GOAWAY received , using Java 11 environment. anyway to resolve this exception rather than moving to Http/1.1 or other HTTP client libraries?

here is the stack trace

Answer 1

This is something that your code will just have to deal with.

A GOAWAY frame has been sent by the HTTP 2.0 server that your client is talking to. That means that the server has decided to shut down the connection for some reason. The only thing that the client side can do is tell the caller via an IOException .

This is analogous to an HTTP 1.x server doing a TCP reset... or just disconnecting. These will also result in a client-side IOException .

So, the solution is to catch the IOException and handle it; eg by reporting to the user that the request has failed, or retrying the HTTP request using a fresh connection.

(If you retry, you need some strategy to avoid your client code repeating a request that is never going to succeed. Indeed, ill-advised retrying can actually make things worse, if the reason that the server disconnected is that it is overloaded.)

---

I doubt that switching to HTTP 1.1 would help. I would expect that you would continue to get "random" IOExceptions ... with a different message... from the server using HTTP 1.1.

---

There were a couple of JDK bugs related to GOAWAY handling in HTTPClient, but they were marked as resolved in 2018. You can use this query to find them:

• https://bugs.openjdk.java.net/browse/JDK-8198947?jql=text%20~%20%22httpclient%20goaway%22. )

I don't think they are relevant if you are using the latest version of JDK 11.

Answer 2

I believe that given GOAWAY is send from server to "idle connection after being idle too long". Generally, you can configure to not log such exception if they occur in client holding connection on background.

In your case I see, that exception is thrown from your code:

com.abcd.common.RequestProcessor.getRequest(RequestProcessor.java:49)

This is not case described at the beginning of my answer.

What is "random point in time"? Is it during http call? Does server wait for longer period of time for your input to be sent?

PS: There is also great chance, that after your 1000th request using single TCP connection, server does close connection. It is a default value for nginx at least. See https://www.androidbugfix.com/2022/03/how-to-handle-http2-goaway-with.html for more info.

Answer 3

try adding ".version(HttpClient.Version.HTTP_1_1)" in your http request
