I might be doing the wrong thing conceptually, so pls tell me if I'm wrong.
I'm signing in a user client-side using Parse's Facebook sign-on. I then am trying to post this user object to my server so I can have that user object server-side, but I can't find anything in the docs regarding this.
Do I have to simply pass the user.objectId and then re-fetch that user server-side? Or is there a way to actually pass this user and then set it as Parse.User.current() on the server?
So I just had to get the auth'd sessionToken from the client-side login and post it server-side.
Here's the client-side Facebook login. fblogin is called when user clicks the login button. I've also left out the basic Parse/FB init:
function fblogin() {
console.log("fblogin -- start");
Parse.FacebookUtils.logIn(null, {
success: function(user) {
if (!user.existed()) {
postFBLogin(user);
} else {
console.log("fblogin -- else -- user.sessionToken = " + user._sessionToken);
postFBLogin(user);
}
},
error: function(user, error) {
alert("User cancelled the Facebook login or did not fully authorize. Error =" + error.message);
}
});
}
function postFBLogin(user) {
console.log("postFBLogin -- start -- user = " + user);
var sessionToken = user._sessionToken;
// Post the login
$.ajax({
url: '/fblogin',
type: 'post',
// dataType: json,
data: {sessionToken: sessionToken},
success: function(data) {
console.log("post error = " + data.errorCode + data.errorMessage);
if (data.status === 200) {
// window.location = '/home/language';
}
// If an error, show the prompt
if (data.errorCode === 101) {
$('#login-alert').show().text("Facebook login error.");
}
},
error: function(error) {
console.log("postFBLogin -- post error = " + data.errorCode + data.errorMessage);
}
});
}
And then server-side, I'm using become() of the Parse.User class to take that sessionToken and turn it into an auth'd user server-side:
exports.fblogin = function(req,res) {
// var defaultLanguage = req.app.get('defaultLanguage');
var sessionToken = req.body.sessionToken;
Parse.User.become(sessionToken).then(function (user) {
console.log("exports.fblogin -- become -- success");
// The current user is now set to user.
res.redirect('/home/language');
}, function (error) {
// The token could not be validated.
console.log("exports.fblogin -- become -- error = " + error);
});
}
When you call a Cloud Function, or a Before/AfterSave method fires, you have access to the user already:
Parse.Cloud.define('myFunction', function(request, response) {
// the current user is in: request.user
});
