Issue with the submitAdapterAuthentication() method of the ChallengeHandler in MobileFirst v.6.3 - callback

Question

We have an issue with the submitAdapterAuthentication() method of the ChallengeHandler in IBM MobileFirst v.6.3.
We assign callback functions to the properties 'onSuccess' and 'onFailure' in the options object.
We then provide the options object to submitAdapterAuthentication(invocationData, options) and execute it.
var ch = WL.Client.createChallengeHandler(securityTest);
//////////////////
function login (user, pass) {
tempUser = {username: user, password: pass};
userObj.user = user;
var auth = "Basic " + window.btoa(user + ":" + pass);
var invocationData = {
parameters: [auth, user],
adapter: "SingleStepAuthAdapter",
procedure: "submitLogin"
};
var options = {
onSuccess: iWon,
onFailure: iLost,
invocationContext: {invocationData: invocationData},
timeout: 10000
};
ch.submitAdapterAuthentication(invocationData, options);
});
function iWon(response) {
WL.Logger.debug('Login success! Response: ' + JSON.stringify(response));
//update user info, as somehow isUserAuthenticated return false without it
WL.Client.updateUserInfo(function(response) {
WL.Logger.debug('Updated User Info success! Response: ' + JSON.stringify(response));
});
}
function iLost(response) {
WL.Logger.debug('ERROR. Login failed! Response: ' + JSON.stringify(response));
}
Neither the onSuccess (iWon) or the onFailure (iLost) is called after executing submitAdapterAuthentication(invocationData, options).
How do we know if the authentication was successful?
Which options, events, callbacks or promises shall we look for and use?
We have also posted the issue here:
submitAdapterAuthentication not working

Answer 1

You are missing the definition of the functions
ch.isCustomResponse = function(response){...}
ch.handleChallenge = function(response){...}
Your code should look more like this
var ch = WL.Client.createChallengeHandler(securityTest);
ch.isCustomResponse = function(response) {
if (!response||!response.responseJSON||response.responseText === null) {
return false;
}
if (typeof(response.responseJSON.authRequired) !== 'undefined'){
return true;
} else {
return false;
}
};
ch.handleChallenge = function(response){
var authRequired = response.responseJSON.authRequired;
if (authRequired == true){
// handle the case when authentication is needed, i.e., show login form etc.
if (response.responseJSON.errorMessage) {
// authentication failed, show a message to the user indicating what went wrong
// call the login failed function or move it's contents here
iLost(response);
}
} else if (authRequired == false){
// no authentication is needed
ch.submitSuccess();
// call the login success function or move it's contents here
iWon(response);
}
};
//////////////////
function login (user, pass) {
tempUser = {username: user, password: pass};
userObj.user = user;
// is the first parameter expected by submitLogin the username or the
// Basic Authentication encoded string ???
var auth = "Basic " + window.btoa(user + ":" + pass);
var invocationData = {
parameters: [auth, user],
adapter: "SingleStepAuthAdapter",
procedure: "submitLogin"
};
ch.submitAdapterAuthentication(invocationData, {});
});
function iWon(response) {
WL.Logger.debug('Login success! Response: ' + JSON.stringify(response));
//update user info, as somehow isUserAuthenticated return false without it
WL.Client.updateUserInfo(function(response) {
WL.Logger.debug('Updated User Info success! Response: ' + JSON.stringify(response));
});
}
function iLost(response) {
WL.Logger.debug('ERROR. Login failed! Response: ' + JSON.stringify(response));
}
