Subject ServerSocket , Chunked data , and BufferedReader
Date Tue, 12 Apr 2016 15:53:51 GMT
I'm trying to use a "ServerSocket" to receive HTTP messages from a client
which is POSTing them as chunked.  I just want to capture the text content
being posted (plain text).  Any input on how to do this better would be

Here is my existing and very not-elegant solution.  When dealing with
ServerSocket, one has to handle the headers and chunk barriers manually,
and this is what I came up with.  I looked at filterline method on the
reader, maybe that's part of a solution, i'm not sure.

socket.withStreams { input, output ->
BufferedReader reader = new BufferedReader(new InputStreamReader(input))
while (currentLineCount < processor.newLineCount) {
line = reader.readLine()

if (line && line.size() > 3) {


1.  I have been trying to process line by line to minimize memory impact,
rather than buffering the whole collection. I'd like to keep it that way.

2.  These 4 Jetty libraries are available on the classpath, so I could
leverage them, but can't add other libraries.

    compile 'org.eclipse.jetty:jetty-server:8.1.2.v20120308'
    compile 'org.eclipse.jetty:jetty-continuation:8.1.2.v20120308'
    compile 'org.eclipse.jetty:jetty-io:8.1.2.v20120308'
    compile 'org.eclipse.jetty:jetty-util:8.1.2.v20120308'

I would make the Service and Handler in Jetty, but I can't find any good
examples that fit my situation.
