How to use Alamofire with Facebook Login?

Question

After retrieving an access token from Facebook, I'm trying to use the token to connect with an OAth2 server. When I try and connect I keep getting a 401 Unauthorized access code but when the backend developers connect it works. Here is the Curl from the backend developers that works:

curl -X POST -H "Content-Type: application/json" -d '{
    "client_id" : "1",
    "access_token" : "EAARDjZAZBQnEEBAAxLZAE08npCWTeXUTQIHnP5rKx4poRZAlBAhL7UW6RJIUhZBmomIaIoNm97ERmVi0g2Ql5rfLZBckWf31hnOV6TCHkI8Tu4IBNknFBMsbaI8NvPl7aOp2qHhaAKaHx4UkwGJ9Eo8sZAaJhN7v0M7aCwNpUE3HgZDZD"
}' "http://localhost:3000/auth/facebook"

Here is my alamo fire code:

func facebookAPILogin (fbAccessToken: String, completionHandler: (ErrorType?) -> ()) {


  let headers = [

    "Content-Type": "application/json"

  ]

  let parameters: [String: AnyObject] = [

    "client_id" : "1",
    "access_token" : fbAccessToken

  ]


  Alamofire.request(.POST, "\(baseTestOathURL)facebook", encoding: .JSON, headers: headers)
    .validate()
    .responseJSON { response in
      switch response.result {
      case .Success:
        print("Validation Successful")

        guard let value = response.result.value else {

          completionHandler(response.result.error)
          return
        }

        let swiftyJsonVar = JSON(value)


          print("This is the FaceBook response \(swiftyJsonVar)")

        completionHandler(nil)

      case .Failure(let error):

        print("Sorry there was an error: \(error)")

         completionHandler(error)

        return
      }

      }

}

I can't figure out hwy I can't connect, any help will be appreciated.

You are forgetting to pass the parameters.

Try this:

Alamofire.request(.POST, "\(baseTestOathURL)facebook", parameters: parameters, encoding: .JSON, headers: headers)
