Authenticated HTTP Swift Alamofire Request

I'm struggling to get this to work to make a request to my API. It works without tokens, but when I try to add additional headers, everything becomes complicated for me.

The first is structure. one class is called: APIAsyncTask , which makes requests

one class called APIParams , just a data holder for sending parameters to the APIAsyncTask class.

one class called DatabaseAPI , which forces it to create parameters and send them to the APIAsyncTask class.

DatabaseAPI

func someMethod() { let task = APIAsyncTasks() task.registerCallback { (error, result) -> Void in print("Finished task, back at DatabaseAPI") } let params2 = APIParams(request: .GET, apiPath: "Posts/1", apiToken: "4iTX-56w") task.APIrequest(params2) }

APIAsyncTask

This part is intended to fix another error, because the manager was not global, the task was quickly canceled.

 var manager : Manager! init(authenticatedRequest : Bool, token: String?) { manager = Alamofire.Manager() print("Pre \(manager.session.configuration.HTTPAdditionalHeaders?.count)") if(authenticatedRequest && token != nil) { var defaultHeaders = Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders! defaultHeaders["Authorization"] = "bearer \(token)" let configuration = Manager.sharedInstance.session.configuration configuration.HTTPAdditionalHeaders = defaultHeaders manager = Alamofire.Manager(configuration: configuration) } print("Post \(manager.session.configuration.HTTPAdditionalHeaders?.count)") }

After making some decisions, it comes down to this part.

  private func GetRequest(url: String!,token : String?, completionHandler: (JSON?, NSURLRequest?, NSHTTPURLResponse?, NSError?) -> () ) -> () { print("Begin Get Request") if(token != nil)//if token is not nil, make authenticated request { print("just before request: \(manager.session.configuration.HTTPAdditionalHeaders?.count)") manager.request(.GET, url, parameters: nil, encoding: .JSON).responseJSON { (request, response, json, error) in print("Get Request (authenticated), inside alamofire request") var resultJson : JSON? if(json != nil) { resultJson = JSON(json!) } completionHandler(resultJson, request, response, error) } } else { //working part without token

Since the code is now, I get an error message:

runtime error

Itself gives an answer using Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders , so that should be fine ...

I suspect this is due to multiple threads, according to this blog. Or, since this is something about CFNetwork, could it be because my API does not use SSL? I disabled NSAppTransportSecurity

I'm a little new to fast, so the examples would be much appreciated! Thankyou!

Thus, most of your code looks solid.

The error leads me to think that CFNetwork finds it difficult to figure out how to calculate the security space for a task. I also assume that you are getting a basic auth call since you are attaching an Authorization header.

Delving into your logic a bit more, I thought you were not attaching your token to the string correctly inside the Authorization header. You need to do the following.

 defaultHeaders["Authorization"] = "bearer \(token!)"

Otherwise, your Authorization header value will include Optional(value) instead of value .

This is the only problem that I see at the moment. If you could give this try and comment, that would be great. I will update my answer accordingly if this does not solve your problem.

Good luck

You can add headers to your query with Alamofire 2 and Swift 2 .
