java.io.IOException: gzip finished without exhausting source

[BillBosiolis]

Hi,

I am using Retrofit (2.0.0-beta2) in an Android application to consume a REST service written in PHP. All the responses are gzipped. Also, I am using a GsonConverter to convert the response to java objects.

In some cases, OKio throws an exception like the one seen below

A response example can be seen below (taken from Fiddler)

Any help would be appreciated.

Thanks,

Do you have access to the raw response? The example you pasted is (obviously) not gzipped, and it's going to be hard to reproduce what's happening here without the exact data.

I'm still going to give it a quick shot, but I can only guess as to the behavior you're seeing which isn't all that useful.

Thanks @JakeWharton

Is it OK if I send you the details privately?

[JakeWharton]

Sure! You can email me at jakewharton@gmail.com.

[BillBosiolis]

OK. This one can be closed. It has nothing to do with retrofit/OkHttp.

In fact, it seems that the problem was that the server code (not Apache) was always sending a Content-Length header back even in cases where chunked encoding was being used.
