Errors handling in web services
From MoodleDocs
I'm looking at how we return errors in the current Moodle web services. Here is the status:
- exceptions are raised: 16 functions
- string error messages: 2 functions (create notes / send messages)
- download/upload script return string error message (JSON) + error code
- When exception are raised, a unique error message is returned. It is format by the protocol server.
REST: <?xml version="1.0" encoding="UTF-8"?> <EXCEPTION class="invalid_parameter_exception">
<MESSAGE>Invalid parameter value detected</MESSAGE> <DEBUGINFO></DEBUGINFO>
</EXCEPTION>
XMLRPC/SOAP: respective error format
