Invalid Token When Using Alamofire

Question

Environment: Swift 2, iOS 9

I had rolled my own HTTP networking library. It wasn't broken but I decided to fix it and switch to Alamofire.

Here is my code snippet:

  case .HTTPTokenAuth:  // Token Auth

  let dictionary = Locksmith.loadDataForUserAccount("Auth_Token", inService: "KeyChainService")
  let token = dictionary!.valueForKey("access_token")

  var aManager = Manager.sharedInstance
  aManager.session.configuration.HTTPAdditionalHeaders = ["Authorization": "Bearer \(token!)" ]
  aManager.request(method, requestURL!, parameters: parameters, encoding: .JSON).response { request, response, data, error in

    print("===== Request ================")
    print(request!.allHTTPHeaderFields!)
    print("===== Response ================")
    print(response!.allHeaderFields)
    print("===== Error ================")
    print(error)

  }

The problem is that for some reason the Oauth token is not making it into the header. (At least that is what appears to be the problem as I don't see it in the Request header. I receive the following request/response:

===== Request ================
["Content-Type": "application/json"]

===== Response ================
[Content-Type: application/json, 
Www-Authenticate: Bearer realm="Doorkeeper", 
error="invalid_token", 
error_description="The access token is invalid",

Answer 1

I went with the simpler approach:

case .HTTPTokenAuth:  // Token Auth

  let dictionary = Locksmith.loadDataForUserAccount("Auth_Token", inService: "KeyChainService")
  let token = dictionary!.valueForKey("access_token")
  let headers = ["Authorization":"Bearer \(token!)"]

  Alamofire.request(method, requestURL!, parameters: parameters, headers: headers, encoding: .JSON)
           .response { request, response, data, error in

    print(request!.allHTTPHeaderFields!)
    print(response)
    print(error)

  }
