Use Alamofire to Set HTTP Headers and HTTP Body

Question

I have been using NSURLConnection to make requests and I would like to migrate the codes to Alamofire.

Here is my NSURLConnection code.

var requestString: NSString = "http://api.domainname.com/api/v1/auth/register";
var url: NSURL = NSURL(string: requestString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)!;

var urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: url);
urlRequest.setValue("\(base64LoginString)", forHTTPHeaderField: "Authorization");
urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type");
urlRequest.setValue("application/json", forHTTPHeaderField: "Accept");

var httpBodyDictionary: NSMutableDictionary = NSMutableDictionary();
httpBodyDictionary.setObject(self.emailTextField.text, forKey: "email");
httpBodyDictionary.setObject(self.usernameTextField.text, forKey: "username");
httpBodyDictionary.setObject(self.passwordTextField.text, forKey: "password");

urlRequest.HTTPMethod = "POST";

NSURLConnection.sendAsynchronousRequest(urlRequest, queue: NSOperationQueue.mainQueue(), completionHandler: { (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in
    if(data != nil) {
          //PROCESS DATA
    }
});

I have however tried Alamofire but I cant make it work..

ALAMOFIRE

var defaultHeaders = Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders ?? [:]
defaultHeaders["Authorization"] = "\(base64LoginString))"
defaultHeaders["Content-Type"] = "application/json)"
defaultHeaders["Accept"] = "application/json)"

let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
configuration.HTTPAdditionalHeaders = defaultHeaders;

let manager = Alamofire.Manager(configuration: configuration)


var requestString: NSString = "http://api.domainname.com/api/v1/auth/register";
var url: NSURL = NSURL(string: requestString.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!)!;

var urlRequest: NSMutableURLRequest = NSMutableURLRequest(URL: url);
urlRequest.HTTPMethod = Alamofire.Method.POST.rawValue;

let parameters = ["email": self.emailTextField.text,
        "username": self.usernameTextField.text,
        "password": self.passwordTextField.text]

do {
        urlRequest.HTTPBody = try NSJSONSerialization.dataWithJSONObject(parameters, options: NSJSONWritingOptions())
} catch {
    // No-op
}

Alamofire.request(urlRequest).responseJSON(completionHandler: { (urlRequest, urlResponse, result) -> Void in
        print(urlResponse);        
    //print(result);
})

Could anyone please point to the right direction please? I have spent the whole day trying to make it work.

Note: Using Swift 2/ XCode 7 Beta 6

UPDATE tried Rob's suggestion but instead I get this returned, this does not happen when I use NSURLConnection

You don't have to set Content-Type or Accept . You also don't have to set the request body nor use NSJSONSerialization yourself. Alamofire gets you out of the weeds of constructing requests. So you might do something like:

let requestString = "http://api.domainname.com/api/v1/auth/register"

let parameters = [
    "email"    : emailTextField.text!,
    "username" : usernameTextField.text!,
    "password" : passwordTextField.text!
]

let headers = ["Authorization": base64LoginString]

Alamofire.request(.POST, requestString, parameters: parameters, encoding: .JSON, headers: headers).responseJSON { request, response, result in
    print(response)
}

Or, alternatively, if you don't want to build the base64LoginString yourself, you might also be able to do something like:

Alamofire.request(.POST, requestString, parameters: parameters, encoding: .JSON)
    .authenticate(user: user, password: password)
    .responseJSON { request, response, result in
        print(response)
}

If it's still not working, I'd suggest (a) edit your question, sharing the precise error messages; and (b) observe both your old code and the new code in a tool like Charles and identify how precisely the two requests differ.
