Hi,

I'm starting to look at the API and i mess around.
I'm trying to connect to the API, without success. I always got a http error 500.

My limesurvey installation is locate at vecteursleviers.com/conseil/index.php?r=admin
I also got an http error 500 when I try do display the /conseil/ folder.

The jsonrpcphp library from github is intalled in a folder name api on my web server. The client can be found at the url vecteursleviers.com/conseil/api/jsonrpcp...r/src/org/jsonrpcphp

I've create a php file at this location vecteursleviers.com/conseil/api/API-Lime-JLT.php and add this code.
The *** are my my verified login infos.

Can you help me find where I got wrong?

Thanks for your precious help!


<?php

// without composer this line can be used
// require_once 'jsonrpcphp-master\src\org\jsonrpcph\jsonRPCClient.php';
// with composer support just add the autoloader
include_once 'vendor/autoload.php';

define( 'LS_BASEURL', ' vecteursleviers.com/conseil/ '); // adjust this one to your actual LimeSurvey URL DONE
define( 'LS_USER', '***' );
define( 'LS_PASSWORD', '***' );

// the survey to process
$survey_id=374699;

// instanciate a new client
$myJSONRPCClient = new \org\jsonrpcphp\JsonRPCClient( LS_BASEURL.'/admin/remotecontrol' );

// receive session key
$sessionKey= $myJSONRPCClient->get_session_key( LS_USER, LS_PASSWORD );

// receive all ids and info of groups belonging to a given survey
$groups = $myJSONRPCClient->list_groups( $sessionKey, $survey_id );
print_r($groups, null );

// release the session key
$myJSONRPCClient->release_session_key( $sessionKey );
add_participants

If it can helps you, please find a piece of working code to perform some connection tests...

1) Create a file & place it at your root limesurvey folder (same level as index.php)
2) edit the first block (url + user+ passw + survey ID)
3) call the file

You will also find some useful info at:

Thanks for your precious help!

I still get a HTTP ERROR 500

vecteursleviers.com/conseil/api-test.php

The JSON-RPC API is enable and it's published on admin/remotecontrol.

Any idea?

Thanks again!

I would:

1) check server error logs about this error 500

2) turn debug mode on in application/config/config.php

Thanks again for your precious help.

Here's the logs. I've changed my password to ***.

Maybe allow_url_fopen is turned off?
Check your php.ini

In this case you should access a valid webpage (status 200) with some text when connecting to:

www.vecteursleviers.com/conseil/index.php/admin/remotecontrol

It's not the case (redirect to home page) and you have to focus on this first before starting any other test.

IMHO there is something wrong in your server configuration... could be about "allow_url_fopen" or similar... I don't really know and hard to guess...Sorry !

Thanks a lot Jacob and Ben_V for your precious help!

Unfortunately, I added allow_url_fopen to my php.ini file and It does'nt do anything.

In the API setttings, it's been displayed that the API is publish at the URL : vecteursleviers.com/conseil/index.php?r=admin/remotecontrol

Should it be at www.vecteursleviers.com/conseil/index.php/admin/remotecontrol ?

I'm looking towards my server config!

Thanks again!

Found the solution from this post: www.limesurvey.org/forum/installation-a-...st-page-doesn-t-work

in config.php

I've changed
'urlManager' => array(
'urlFormat' => 'get',

to

'urlManager' => array(
'urlFormat' => 'path',

And now RemoteControl works as expected?

Good to know... thanks for your feedback

Congrats!!!

Hi Jacob,

vecteursleviers.com/conseil/api-test.php ssems to works with Ben_V script.
vecteursleviers.com/conseil/index.php/admin/remotecontrol show the different routines.

Everything seems normal!

Thanks again for your precious help!

I Know this is old, but there may be someone who can help me. I Used the same code as the thread creater, however there is an error in the following line:

$myJSONRPCClient = new \org\jsonrpcphp\JsonRPCClient( LS_BASEURL.'/admin/remotecontrol');

,,jsonrpcphp" seems to be an undefined namespace. I´m not new to programming, but never used php. The jsonrpc-folder is in my limesurvey-root: localhost/umfragen_test/jsonrpcphp-master/...
I followed the tutorial. Is there something i´m missing?.

Nevemind fixed it. The JsonRPCCLient.php was not in my Limesurveyroot.
