Competition Task Overview
For this contest, we are going to support social logins like , Google, Facebook, Twitter, Github and Salesforce by using www.auth0.com.
Please register your own account for development.
The implementation will based on branch - https://coder.topcoder.com/internal/web_module/branches/tc_reg_revamp
Registration Flow Update
Previously, when clicking the Register Now button on the top-right conner of the http://www.topcoder.com/tc page, it will redirect to https://www.topcoder.com/reg/ to start the new user registration process.
Now, we'd like to revise the flow to add social login features.
- When clicking the Register Now button on the top-right conner of the http://www.topcoder.com/tc page, a standard Registration Modal provided by www.auth0.com will be shown to start the registration process.
- Make the Signup link lead to https://www.topcoder.com/reg2/showRegister.action
- Remove the Forget Your Password? link
- For directly Signin, you can leave it now, we will try to configure LDAP later.
- After successfully login with social, it will return to the callback url, then the callback will retrieve the user data and pre-fill in register form at page https://www.topcoder.com/reg2/showRegister.action
- the /reg2 code should be updated to take the user data and pre-fill in the form.
- the social related info should be set as hidden data in the form, so it can be saved after clicking the Register button
- /reg2 need to remember where to redirect after reg is done
- After filling all the data, and clicking the Register button, user will be created with social data.
- please store username in the user_social_login table in scripts trunk.
- user will redirect to the previous page for starting the registration. For auth0, it is using "state" parameter to remember the redirect page, please check API doc for more
Login Flow Update
Previously, when clicking the Login link on the top-right conner of the http://www.topcoder.com/tc page or other pages, it will redirect to http://community.topcoder.com/tc?&module=Login to start user login process.
Now, we'd like to revise the flow to add social login features.
- At Login page, we will add a new Login Widget inside a Div that the right side of the current Login form. Use the standard Login Widget provided by www.auth0.com will be shown to start the login process.
- After successfully login with social, it will return to the callback url, it will try to search the user and get the user login automatically.
- To search user, use a query in query tool to search by social login data, if exists (we can combine the roles in this same query if makes sense), this will then set the TCSubject, and all the cookies, any necessary setup the same logic as after login ejb.
- Please check LoginAction.java Login.java and BasicAuthentication.java for reference about the logic.
- After successfully login, user will be redirected to the page previous visit when clicking the Login link. For auth0, it is using "state" parameter to remember the redirect page, please check API doc for more
