About SimpleHTTPServer
Hi all,
Does Groovy provide any function like Python's SimpleHTTPServer(e.g.
python -m SimpleHTTPServer 8000)? If no similar module exits, I'd like to
implement one via Groovy 3(e.g. groovy -m SimpleHTTPServer 8000).
FYI: https://docs.python.org/2/library/simplehttpserver.html
Cheers,
Daniel.Sun

Hi Remi,
Your reply is always so helpful :-)
As far as I remember, Sun introduced the http server in Java6. It's
lucky for us that it's included in the OpenJDK too.
Cheers,
Daniel.Sun

FYIW, there is already an httpserver with the jdk
http://hg.openjdk.java.net/jdk9/jdk9/jdk/file/tip/src/jdk.httpserver/share/classes/com/sun/net/httpserver/package-info.java

Thanks for your suggestion, mrhaki :)
In order to avoid maintaining the httpserver, I'd like to use the built-in
httpserver of JDK.

Hi,
the following code snippet can be used as inspiration:
https://github.com/mrhaki/groovyrun-gradle-plugin/blob/master/src/main/groovy/com/mrhaki/gradle/groovyrun/SimpleHttpServer.groovy
It has no 3rd party dependencies and uses the Groovy socket support.
Kind regards, Hubert Klein Ikkink

As such a feature is not core for a programming language, it will not
be updated frequently ;)

I understand this is not for Production use. ;)
My concern is that an HTTP server built into groovy would come with its
potential risks \u2013 even it is not used directly. Having to redeploy an
app where groovy is embedded because of an issue with such a
non-critical feature would be somewhat... frustrating.
As a groovy user, I want to make sure the pros and cons are carefully
considered before adding this to core. My personal preference would be
to have this feature as part of an optional groovy library, but maybe
it's just me. :D

S�bastien.

There are com.sun classes and com.sun classes :)
These ones are exported
http://hg.openjdk.java.net/jdk9/jdk9/jdk/file/tip/src/jdk.httpserver/share/classes/module-info.java
so ok to use.
Said differently, they are not part of Java but part of the OpenJDK.

Hi Paul,
The built-in httpserver of JDK suggested by Remi seems better for us,
it is stable and does not require 3rd party library:
http://hg.openjdk.java.net/jdk9/jdk9/jdk/file/tip/src/jdk.httpserver/share/classes/com/sun/net/httpserver/package-info.java
As to hooking to the existing socket server, I think it feasible as
mrhaki showed the relevant sample code, but we have to maintain it... so I
would like to implement SimpleHTTPServer based on the built-in httpserver.
Cheers,
Daniel.Sun

I should have mentioned the above example is more about illustrating
groovlets rather than serving up static content but it isn't too hard
to switch between the two.

Re: About SimpleHTTPServer

I don't know whether you would find listing 12.16 from ReGinA useful:
It is based on Jetty rather than com.sun.net.httpserver.HttpServer but
might provide some useful inspiration:
https://github.com/Dierk/GroovyInAction/blob/master/listings/chap12/Listing_12_16_GroovletExample.groovy
Also, I don't know whether you need a separate -m switch or whether
you could hook into the existing "listen on port (-l port)"
functionality but modify it to accept a class name.
Cheers, Paul.

Hi Sébastien,
The SimpleHTTPServer will be implemented with NO 3rd part library, so
it will not impact existing production systems. In addition, it is
recommended to be used to provide http service for convenience(such as
testing WebRTC app). If we want to deploy our static web site, the
SimpleHTTPServer is not recommended to be used in production :)
Cheers,
Daniel.Sun

As a separate library, this would indeed be a nice feature to have \u2013 but
as a core Groovy feature, I am bit more wary that this would cause bloat
and bring in potential vulnerabilities that users don't necessarily want
to worry about in production apps.

Yeah, I think so too, but I'm not sure whether Groovy already has some
similar function or not...

Re: About SimpleHTTPServer

Hi Jochen,
Given we have a directory containing some web pages and want to
access these pages via http protocal(e.g. we want to test WebRTC app), we
have to run a httpserver to provide http service. In the past, we have to
use Python to achieve the requirement because its SimpleHTTPServer is very
easy to use, just run "python -m SimpleHTTPServer 8000" to serve files of
current directory. As you know, my favorite programming language is Groovy,
so I want to find or implement similar function in Groovy :)
If I implement it, I want to rely on NO 3rd part library(e.g.
netty). It's lucky that JDK provide a httpserver as Remi suggested. Groovy's
SimpleHTTPServer can rely on it ;)
Cheers,
Daniel.Sun

something like:

would do the job I think... didnt test it and the servlet-api stuff
could get in the way.
If all you want is Groovy listening on a port and evaluate the scripts
you give it, that is something we have already. So the question to be
answered would be... what do you intend to do with the http server?
