Hey guys,

I'm just trying to execute a query using EMAPI...
 
heres the Code...
 
       ExtQuery = "<query>/n";
                ExtQuery += "<appInfo> /n";
                ExtQuery += "<appID>admin</appID> /n";
                ExtQuery += "<appCertificate>p1tBas!c</appCertificate> /n";
                ExtQuery += "</appInfo> /n";
                ExtQuery += "<userDevicesQuery> /n";
                ExtQuery += "<userID>" + UserID + "</userID> /n";
                ExtQuery += "</userDevicesQuery> </query>/n";        
 

 
   HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://192.168.200.15/emservice/EMServiceServlet");
 

   req.Accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*";
            req.ContentType = "application/x-www-form-urlencoded";
            req.Method = "POST";
            req.KeepAlive = true; 
 
            Stream s = req.GetRequestStream();
            s.Write(System.Text.Encoding.ASCII.GetBytes(ExtQuery), 0, ExtQuery.Length);
            s.Close();
            WebResponse resp = req.GetResponse();
            StreamReader sr = new StreamReader(resp.GetResponseStream());
            string XMLResult = sr.ReadToEnd();
 
Im getting an Error 500 Internal server error...
 
does anyone have any suggestions? if i browse to the URL i also get an error 500 page.

very odd...
 
there must be multiple causes for this then!!!
 
i only have a publisher.. its a vmware test machine...
 
anyhoo i think it was my headers...
 
In case anyone is curious I got it working with this:
 

   ExtQuery = "xml=<query>";
                ExtQuery += "<appInfo> <appID>admin</appID> <appCertificate>p1tBas!c</appCertificate> </appInfo>";
                ExtQuery += "<userDevicesQuery> <userID>"+UserID+"</userID> </userDevicesQuery>";
                ExtQuery += "</query>";

 

       HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://x.x.x.x:8080/emservice/EMServiceServlet");
 
            req.Accept = "text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2";
            req.ContentType = "application/x-www-form-urlencoded";
            req.Method = "POST";
            req.KeepAlive = true;
 
            Stream s = req.GetRequestStream();
            s.Write(System.Text.Encoding.ASCII.GetBytes(ExtQuery), 0, ExtQuery.Length);
            s.Close();
            WebResponse resp = req.GetResponse();
            StreamReader sr = new StreamReader(resp.GetResponseStream());
            string XMLResult = sr.ReadToEnd();

may you say how to work this services on IP phones??
userid ,machine id e.g values how to take??

Hi Dan,
 
I think I found "your" fault ... it isn't really yours, it is more to the developer or those who write the documentation.
1. Although you might think we are talking XML, no, we don't. That means no xml header like <?xml version=1.0> etc. Just use simple string.
2. urlencode the xml based em api call "urlencode("<query>...some content ...</query>");"
3. prepend an xml= (not urlencode!) to encoded xml (see step 2).
4. use HTTP header "Content-Type: application/x-www-form-urlencoded"
 
that should work. In your example you miss step 3 I think.
 
Kind reagards
