sending accessToken to server using swift ios - ios

Question

I am trying to use facebook ios login sdk. I get the access Token using below code. Now i want to send this token to a server so that server can validate this token by making a call to facebook server.
I am using the below code to get the accessToken , i am using swift in ios 8.
var accessToken = FBSession.activeSession().accessTokenData
When i am trying to send this token to server getting an error saying that type of accessToken is not convertible to NSString.
Please help me where i am wrong.

First, make sure that you have an open session. I use this approach in my AppDelegate:
FBSession.openActiveSessionWithAllowLoginUI(false)
Second, you can get accessToken as a string from accessTokenData:
var myToken = FBSession.activeSession().accessTokenData.accessToken
From there, you can send it to your server however you want. I tried a couple request wrappers until I settled on Net. Getting your token to your server is pretty easy if you have a library like Net so that you don't have to handle the low level network request interfaces:
func doLogin() -> Void {
let net = Net(baseUrlString: "http://myhost.com/")
let url = "auth/facebook_access_token"
let params = ["access_token": myToken]
net.GET(url, params: params, successHandler: { responseData in
let result = responseData.json(error: nil)
// Do something with whatever you got back
NSLog("result \(result)")
}, failureHandler: { error in
NSLog("Error")
})
}
Good luck! I hope I was able to help!
