there is a Zend server for JSON: http://framework.zend.com/manual/en/zend.json.server.html
It seems pretty close to the other Zend server, it should not be to hard to do.

+1 for json support, thanks!

NOTE: This issue was assigned to the STABLE backlog without complete triaging process. Marking it as triaged, but with this note for future reference.

+1 For JSON support for me.

Any idea of progress on this?

I need it for something I am working on, so have quickly created my own JSON web service server using the REST version as a base.

Have attached my code as a zip... might be a good starting point to get this feature into core.

Big thanks for this good patch Jason! It is a good start.

It should be even quicker to create a full JSON server/client. I'd vote for this issue if I wasn't the reporter (reporter can't vote )

Any update on this feature?

I've added the latest version of my json web server into my git hub.

https://github.com/jason-platts/moodle/commit/1dfb4268244a5114773a2e62e417c577d8e1c439

Essentially it's the same as the current rest service but uses php json_encode as the output.

I haven't included json-p callback as I don't have any use for it - but this would be trivial to add.

I can submit for integration if it looks like it would do the business.

Hi, Jason

We are really busy on moodle 2.1 release at the moment (this week). I am looking forward to seeing json protocol included in core.

Thanks for your work.

I'd like to get JSON server support into Moodle 2.2 as this issue has been unresolved for a long time.

Could someone code review my suggested web-service plugin to support this inclusion?

Thanks.

Hi Jason

I proposed json web service protocol in 2.2 roadmap, we will integrate it when we start to working on dev backlog, there are plenty tasks waiting in the queue at the moment, we are trying very hard to fix them one by one, we will get there

Dongsheng

Thanks Dongsheng.

Hi,
since 2.2 the REST server returns JSON format like Jason's patch.

However the issue title itself is still standing. Would it be usefull to have a full JSON server? A server that receive some JSON string as parameter ? If yes it's not too hard to implement.

One advantage I can see of a full JSON is that it makes the life easier for the client as almost all language knows how to encode JSON. Also it resolve some of the REST issue like sending an empty array by POST.

In fact we could still keep our REST server, adding a 'fulljson' format to the current 'xml' and 'json' format.

I decrease the issue priority as the original request has been implemented REST/JSON.

Btw thanks for your contribution Jason.

I will not be able to work on this issue in the immediate future. In order to create a truer sense of the state of this issue and to allow other developers to have chance to become involved, I am removing myself as the assignee of this issue.
For more information, see http://docs.moodle.org/dev/Changes_to_issue_assignment

I needed a webservice that could take JSON input for a project I've been working on, so have put together one that takes this based on the current REST server:

https://moodle.org/plugins/webservice_restjson

It basically just looks at the content-type header to determine whether it's receiving JSON, XML or webform data and the content-type and accepts headers to determine which format to return, and should be backward compatible with the current REST server.
