Grouper Users - Open Discussion List

[Ben Beecher <>]

Robert,

Thanks for sending the sample request in XML format. I was able to access the web service using that example. My Python code generates JSON and I get an error in the log when I use that request format with JSON:

2017-11-28 11:18:52 ERROR WsRestRequestContentType:204 - Error unparsing string with converter: edu.internet2.middleware.grouper.ws.rest.json.DefaultJsonConverter, {"WsRestGetMembersRequest": {"memberFilter": "Immediate", "includeSubjectDetail": "T", "wsGroupLookups": {"WsGroupLookup": {"groupName": "mystem:mygroup"}}}}

2017-11-28 11:18:52 ERROR GrouperRestServlet:226 - Problem with request:  uri: /grouper-ws/servicesRest/v2_3_000/groups, method: POST, decoded url strings: 0: 'v2_3_000', 1: 'groups'

java.lang.RuntimeException: Problem unparsing string with converter: edu.internet2.middleware.grouper.ws.rest.json.DefaultJsonConverter, {

    "includeSubjectDetail":"T",

    "wsGroupLookups":{

      "WsGroupLookup":{

      }

    }

  }

}

at edu.internet2.middleware.grouper.ws.rest.contentType.WsRestRequestContentType$4.parseString(WsRestRequestContentType.java:205)

I was able to get the JSON code working when I changed the request format from this:

        body = {                                                                                    

          "WsRestGetMembersRequest": {                                                              

            "includeSubjectDetail": "T",                                                            

            "memberFilter": "Immediate",                                                            

            "wsGroupLookups": {                                                                     

              "WsGroupLookup": {                                                                    

                "groupName": groupName                                                              

              }                                                                                     

            }                                                                                       

          }                                                                                         

        }                                                                                           

to this:

        body = {

          "WsRestGetMembersRequest": {

            "includeSubjectDetail": "T",

            "memberFilter": "Immediate",

            "wsGroupLookups": [{

              "groupName": groupName

            }]

          }

        }

I spent about seven hours trying different variations so I am really glad it's working now.

I found that the following worked for me (using Kerberos/SPNEGO
authentication):

$ curl --negotiate -u:
'https://<grouper-ws-host>/servicesRest/v2_2_000/groups' --data
"@get_members.xml" --header 'Content-Type: text/xml; charset=UTF-8'

with get_members.xml reading:

<?xml version="1.0" encoding="UTF-8"?>
<WsRestGetMembersRequest>
  <includeSubjectDetail>T</includeSubjectDetail>
  <memberFilter>Immediate</memberFilter>
  <wsGroupLookups>
    <WsGroupLookup>
      <groupName>teststem:mygroup</groupName>
    </WsGroupLookup>
 </wsGroupLookups>
</WsRestGetMembersRequest>

This gets sent as a POST request to the non-lite endpoint.

Hope that helps!
