Hello all,
I need your help with consuming the webservice: enrol_manual_enrol_users
My client app is in ASP.NET, and I am using the XML-RPC.NET library to make XML-RPC calls to Moodle.
I should note that I am able to successfully call the web service "core_user_get_users_by_id". However that is a simple case. It takes an Int array as the parameter and returns an object array containing hashtables, one per user record, and with each key-value pair representing a field from the user table.
However for enrol_manual_enrol_users, I can't figure out how I should code the Method call or handle the return object. Indeed, from the Moodle documentation, there is nothing listed under the "Response" heading for this method.
Here is what I currently have, but this is giving me a rather useless "[404] Unknown error" as the response from Moodle. I expect the problem is because I don't really understand how to use the Struct in the method call, or how to obtain the result from Moodle's response.
Here is the interface definition
public interface IMoodle : IXmlRpcProxy {
[XmlRpcMethod("enrol_manual_enrol_users")]
object[] Enrol_Manual_Enrol_Users(Moodle_Enrolment[] input); //Not sure if it should be delcared as object[] or not, as there is no Response described in the Moodle docs.
}
And the Struct that should represent the input parameter for the webservice
public struct Moodle_Enrolment
{
public int roleid;
public int userid;
public int courseid;
[XmlRpcMissingMapping(MappingAction.Ignore)]
public int timestart;
[XmlRpcMissingMapping(MappingAction.Ignore)]
public int timeend;
[XmlRpcMissingMapping(MappingAction.Ignore)]
public int suspend;
}
And here is the code that instantiates the struct, and calls the WebMethod.
Moodle_Enrolment me = new Moodle_Enrolment();
me.courseid = 2 //this defiinately exists in the Moodle database
me.userid = 7; //this defiinately exists in the Moodle database
me.roleid = 1;
Moodle_Enrolment[] meArray = {me}; //Put the enrolment details into an array.
try
{
object[] a = moodleServer.Enrol_Manual_Enrol_Users(meArray); //not sure what the response datatype is
}
catch (Exception ex)
{
//Error handling code goes here
}
When this code runs, an exception occurs on the call to Moodle, and the exception message is:
Server returned a fault exception: [404] Unknown error
So - can you offer any suggestions on how to fix this? I am sure I am doing something wrong here - but the documentation on the webservice enrol_manual_enrol_users is really not helping me much.
Unfortunately this web service is not available in the Moodle test client. Any suggestions on how I can find out about this 404 Unknown Error?
Thanks for your help all,
Mike
