To utilize the DataCloud API we need to obtain a session ID. This ID will be used for all future calls that we make.

First, obtain the username and password from a form on the page. In this case use the jquery selector to grab the two fields with the class .dsuser and .dspass.

var dsuser = $('.dsuser').val();
var dspass = $('.dspass').val();

Then construct the data body to be sent to the rest call.

var dataObj = 'username=' + dsuser + '&password=' + dspass;

We will then call the function that will make the rest call. We need to specify a response handler. In this case it is hdlLogin.

The call to the function:

restCall('login', 'POST', dataObj, hdlLogin, hdlLogin);

The function definition:

var restCall = function(methodCall, type, requestData, response, responseHandlerFailure) {
   var reqObj = {
      url: 'https://datacloud2.pervasive.com/cloudrest/' + methodCall,
      method: type,
      requestData: requestData,
      requestHeaders: {
         Accept: 'application/xml',
      },
      onSuccess: responseHandler,
      onFailure: responseHandlerFailure
   }
   sforce.connection.remoteFunction(reqObj);
}

The response handler "hdlLogin()" is defined as:

var hdlLogin = function(data) {
   var jsondata = eval("(" + data + ")");
   if (jsondata.success == 'false') {
      //handle failed login
   } else {
      //store off the sessionid for future calls
      sessionId = jsondata.sessionId;
      //handle successful login
   }
}
