[2.0.4] Setting File Upload Size Limit

[Jay Park]

Hi everyone, 

Is it possible by now for Play to limit file upload size? I know in the past it was not possible. 

Thanks!

Java or Scala?  In Scala it's always been possible.  If you want to limit the size of the whole request:

def myAction = Action(parse.maxLength(1024 * 1024, parse.multipartFormData)) { request =>

  ...

}

You can also limit individual parts, but that's a little more involved.

Hi James, 

I thought it is related to Netty's capability. I meant in Java. 

If it is not supported in Java, then I have no choice but to use a front-end web server to work around. 

But then I cannot expect full performance of my Play app because of the proxy, right?

Thanks!

So @BodyParser.Of(value = BodyParser.MultipartFormData.class, maxLength = 1024) doesn't work?

Or are you referring to the fact that Play doesn't terminate the connection early when the limit is reached?

[Jay Park]

It works because I can see browser stop uploading.

However, action does not return result. It looks like action is blocked or something. 

@BodyParser.Of(value = BodyParser.MultipartFormData.class, maxLength = 1024 * 1024)

pulic static Result index() {

  if(request().body().isMaxSizeExceeded()) {

    return badRequest("Too much data!"); // this is not returned

  } else {

    ok("Got body: " + request().body().asText()); 

  }

}

I am seeing the same behaviour Jay. The upload http request is hanging but not terminated and the badRequest call hangs.

So at least the upload size restriction is observed. But not good behaviour.
