| This page is to decide on a STANDARD list of CORE web service functions that we should support in Moodle (by XMLRPC, REST and SOAP with the option to plug in AMFPHP for Flash/Flex interfaces) as an API for those writing code to work against Moodle.
| | {{Template:Work in progress}}{{Moodle_2.0}} |
|
| |
|
| Please add new functions if there's functionality you want that isn't covered (we can refactor/whittle at the end).

| | This page described the Web Services module implemented for Moodle 2.0<br> |
| | The tracker issue is here: MDL-12886<br> |
| | This module is been implemented by the [http://blogs.dfwikilabs.org/moodle_ws/ DFWS Team]. |

| The tracker bug for all this is here: MDL-12886
| | =Implementation= |
| | Web Services module has been conceived in a purpose to be ported on different Moodle version, and also on different project. It has also for purpose to support multiple web service protocols (REST, SOAP, AMFPHP, ...). Adding a new protocol support should be relatively easy. |
|
| |
|
| ==add user== | | == How does it work == |
| I think we should require all data needed for a successful "first login" to Moodle without popping him out the profile page to fill in all missing required data. This may require extra inputs such as city, description ... (unsure of the full list depending of Moodle version ?).
| | The web service client call a Moodle web service. The web service is located in a folder specific to the used protocol. It's usually a inout.php file. This file runs the web service server and gets the sent parameters. Then it calls a wrapper. The wrapper.php file is implemented in order to call the Moodle API which contains all callable functions. The wrapper will check a "generated file" in order to know which functions are available, and what their parameters and what they returned.<br> |
| Also password should be "required" if authentication method is "internal" .
| | For any protocol there should be at least one inout.php file and one wrapper file. |
|
| |
|
| INPUT:
| |
| firstname
| |
| lastname
| |
| email
| |
| idnumber
| |
| login
| |
| authentication method (optional , default= manual ?)
| |
|
| |
|
| | == Technical specs == |
| | # The client calls the web service |
| | # The web service server receives the call |
| | # The web service server transforms the web service params into a common param format to all web service protocol => Format to be defined |
| | # The web service server calls a function call_moodle_function($functionname, $params) |
| | # call_moodle_function() checks through a WS API descriptor class that the params are legal for this function name |
| | # call_moodle_function() call the correct API moodle function |
| | # the call_moodle_function() return the result to the web service server |
| | # the web service server convert the result into a response |
|
| |
|
| | Params should include: |
| | * function parameter names, values and types |
| | * returned object fields (e.g. we cannot return a password field through a get_users function) |
| | * return value and type |

Moodle 2.0
Introduction
This page described the Web Services module implemented for Moodle 2.0
The tracker issue is here: MDL-12886
This module is been implemented by the DFWS Team.
Implementation
Web Services module has been conceived in a purpose to be ported on different Moodle version, and also on different project. It has also for purpose to support multiple web service protocols (REST, SOAP, AMFPHP, ...). Adding a new protocol support should be relatively easy.
How does it work
The web service client call a Moodle web service. The web service is located in a folder specific to the used protocol. It's usually a inout.php file. This file runs the web service server and gets the sent parameters. Then it calls a wrapper. The wrapper.php file is implemented in order to call the Moodle API which contains all callable functions. The wrapper will check a "generated file" in order to know which functions are available, and what their parameters and what they returned.
For any protocol there should be at least one inout.php file and one wrapper file.
Technical specs
- The client calls the web service
- The web service server receives the call
- The web service server transforms the web service params into a common param format to all web service protocol => Format to be defined
- The web service server calls a function call_moodle_function($functionname, $params)
- call_moodle_function() checks through a WS API descriptor class that the params are legal for this function name
- call_moodle_function() call the correct API moodle function
- the call_moodle_function() return the result to the web service server
- the web service server convert the result into a response
Params should include:
- function parameter names, values and types
- returned object fields (e.g. we cannot return a password field through a get_users function)
- return value and type
Security
How are the web services secured ?
Security layer implemented by every protocol?
List of functions
All callable functions are declared into Moodle API, please read Moodle API documentation.
