Question

Hi I am doing facebook login feature in my application. Now problem is that, when I logged in from facebook account, I am redirected to my specified redirected url with access token. I need to grab this access token in managed bean. My redirected url is like that :
localhost:8080/XXXXXX/myholiday.xhtml#access_token=AAAGHUgDJZCg0BAG2I8o

I have tried:

          HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();


    String url = request.getRequestURL().toString();

    System.out.println(url);


    System.out.println( FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("access_token"));


    // Getting request information without the hostname.

    String uri = request.getRequestURI();
    System.out.println(uri);

Output is the following :
localhost:8080/xxxxxxx/myholiday.xhtml

null

xxxxxxx/myholiday.xhtml

can anyone please help me to grab the access token?

Answer 1

You can not get the access token if it is passed in the hash part of the URL, because the hash part does not get transmitted to the server.

You haven’t shown us, how exactly you call the Auth dialog – but it has a parameter response_type that can be set to code or token. codeshould be the default – if you have it set to token, change that.

(Or, if your login gets triggered by Authenticated Referrals, set the Auth Token Parameter setting in your app settings to Query String.)

Then follow the Server-Side Authentication flow from there.
