Im getting ERROR: null W/System.err(20560): java.io.EOFException from a network.request

Solar2D Network
#1 
    local body = "userId=31"     local params = {}     params.body = body network.request( "server/someifle.php", "POST", networkRequestListener, params)

everything work fine, but at some random moments, I get an error in the networkListenerRequests.

If you read this post on stack overflow, http://stackoverflow.com/questions/13182519/spring-rest-template-usage-causes-eofexception

they mention something about an attribute keep alive. Can this be set in corona or does anyone know anything else I can do?

The error message:

E/Corona  (20560): ERROR: null

Just for completion, before Engineering can look at this, can you also post your networkListenerRequests function?

Also, did you just type the code in?  Your network.request() call is missing a quote.  Do you know much about the server in question?  What software is it running?  Apache, IIS? Tomcat?  What version of PHP?  Are you in control of the web server?

Just a typo, missed the first quote, fixed it now.

Listener:

local function networkRequestListener(event)     if ( event.isError ) then         print( "Network error!")         return     end     print("response error:", event.response) end

We are using GAE (Google App Engine), it seem to be PHP version 5.4 with default settings.

I really do not know what to answer to if we are in control of the server, I assume that we can set some of the settings by our own.

Did you find a solution?

I am now seeing this as well on an app that I just updated. I am using the same Corona Enterprise that I used on the build before, so I don’t think it is a Corona issue.

One of the updates was that I changed my backend server from  ASP(IIS) to PHP, maybe it is something related to that?  I also change my http payload response from a JSON type to a base64 data…

I followed the link posted by @kruseborn and was able to solve the problem.

I just had to add a header to force close the connection on the response from my php server.

So, I just added to my PHP page:

header("Connection: close");

and the problem was solved!

Thanks for the link @kruseborn
