swift - Alamofire 相当于 AFHTTPSessionManager

Question

对于 AFNetworking，我遵循了创建 AFHTTPSessionManager 的应用程序特定子类的建议模式。我的看起来像这样:

static NSString* Username = @"";
static NSString* Password = @"";
static NSString* BaseURL = @"https://abc.xyz.com:12345/";

@implementation HttpConnection

+ (HttpConnection*) current {
    static HttpConnection* current = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        current = [[self alloc] initWithBaseURL: [NSURL URLWithString: BaseURL]];
        current.securityPolicy.allowInvalidCertificates = YES;
        current.responseSerializer = [AFJSONResponseSerializer serializer];
        current.requestSerializer = [AFJSONRequestSerializer serializer];
    });
    [current.requestSerializer setAuthorizationHeaderFieldWithUsername: Username password: Password];
    return current;
}

我很好奇我应该如何将此模式转换为与 Alamofire 一起使用。是不是像下面这样？

static let BaseURL = "https://abc.xyz.com:12345/"
static var User = ""
static var Password = ""

func myAppRequest((method: Method, URLString: URLStringConvertible, parameters: [String: AnyObject]? = nil, encoding: ParameterEncoding = .URL) -> Request {
    let request = Alamofire.request(method, BaseURL + URLString, parameters, encoding)
    request.authenticate(user: User, password: "Password)
    return request
}

查看 Alamofire 代码，我有一种预感，它可能会在适当的时间操作 Alamofire.Manager.sharedInstance(应用启动时的 baseURL，以及用户/密码，只要这些发生变化)。但这不太明显(如果确实可能的话)。

我正在使用 Alamofire.Manager 来处理所有请求。我就是这样做的。

//initialize with all details such as referrer etc
self.manager = Alamofire.Manager(configuration: cfg) 


let user = "user"
let password = "password"
// you may manipulate configuration later on if you want.
self.manager.session.configuration.HTTPAdditionalHeaders!["Referer"] = self.host
self.manager.request(.GET, "https://httpbin.org/basic-auth/\(user)/\(password)")
         .authenticate(user: user, password: password)
         .responseJSON { (req, res, json, error) in
            if(error != nil) {
                NSLog("Error: \(error)")
                failure(res, json, error)
                return
            }
            else {
                 // do something with JSON
    }
}
