How to set Facebook Access (from server) in JavasScript SDK -


if using server side flow authenticate user , acquire access token, how can set access token in javascript sdk , use make calls client side?

once user has finished server side authentication flow user authorized app, need use fb.getloginstatus method:

fb.getloginstatus(function(response) {     if (response.status === "connected") {         console.log("authresponse: ", response.authresponse);         fb.api("me", function(response2) {             console.log("hey there " + response2.name);         });     }     else if (response.status === "not_authorized") {         // user logged in facebook hasn't authorized app, should not happen if went through server side authentication     }     else {         // user logged out of facebook, should not happen     } }

as can see can use js sdk query graph, there's no need token manually, in case still need it, authresponse should have following format:

authresponse: {     accesstoken: "aaaaaaa",     expiresin: "bbbbbb",     signedrequest: "cccccc",     userid: "dddddd" }

edit

if user logged facebook , has allowed , interacted app yes getloginstatus should return valid access token.
there few cases in not case, 1 of them being token has expired.

as states in handling invalid , expired access tokens:

desktop web , mobile web apps implement authentication javascript sdk

calling fb.getloginstatus() or ensuring status: true set when call fb.init() means next time user lands on application , signed facebook, authresponse object passed result of calls contain fresh, valid access token.

in case, act of user using application implicitly generates new access token.
