null request body for large data

问题:

I am sending large amount of text in the body of post method. I use Postman for testing that. However its working fine and i can read request body like this:

String text = request().body().asText();

But when i try to send large amount of data in the body i get null for the text. I also tried using the string builder but i also get null.

 InputStream is = new ByteArrayInputStream(request().body().asText().getBytes());
        BufferedReader br = new BufferedReader(new InputStreamReader(is));

Is there a way to get that fixed??

By default Play limits the upload data size to 100kb to text parsers(*). This can be changed to a bigger value globally using parsers.text.maxLength in application.conf

parsers.text.maxLength=4M

or in a specific Response or Action using

@BodyParser.Of(value = TheBodyParser.class, maxLength = 4 * 1024 * 1024)
public Result upload() {
    // (...)
}

or

def upload = Action(parse.text(maxLength = 4 * 1024 * 1024)) { request =>
  // ()
}

(*) To parsers that buffer content (ex multipart form) the limit is 10MB and can be changed using parsers.disk.maxLength
