【问题描述】：

ViewController.swift 调用 Router.createSession(["caio":"teste"]) 中参数 #2 的错误缺少参数

func loginViewFetchedUserInfo(loginView : FBLoginView!, user: FBGraphUser) 
    println("User: \(user)")
    println("User ID: \(user.objectID)")
    println("User Name: \(user.name)")
    var userEmail = user.objectForKey("email") as String
    println("User Email: \(userEmail)")

    Alamofire.request(Router.CreateSession(["caio":"teste"])).response  (request, response, data, error) in
        println(request)
        println(response)
        println(error)
    

Router.swift 文件包含 crud 路由器

enum Router: URLRequestConvertible 
static let baseURLString = "http://www.teste.com.br"
static var OAuthToken: String?

case CreateSession([String: AnyObject])
case ReadSession(String)
case UpdateSession(String, [String: AnyObject])
case DestroySession(String)

var method: Alamofire.Method 
    switch self 
    case .CreateSession:
        return .POST
    case .ReadSession:
        return .GET
    case .UpdateSession:
        return .PUT
    case .DestroySession:
        return .DELETE
    


var path: String 
    switch self 
    case .CreateSession:
        return "/sessions"
    case .ReadSession(let username):
        return "/sessions/\(username)"
    case .UpdateSession(let username, _):
        return "/sessions/\(username)"
    case .DestroySession(let username):
        return "/sessions/\(username)"
    


var URLRequest: NSURLRequest 
    let URL = NSURL(string: Router.baseURLString)!
    let mutableURLRequest = NSMutableURLRequest(URL: URL.URLByAppendingPathComponent(path))
    mutableURLRequest.HTTPMethod = method.rawValue

    if let token = Router.OAuthToken 
        mutableURLRequest.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
    

    switch self 
    case .CreateSession(let parameters):
        return Alamofire.ParameterEncoding.JSON.encode(mutableURLRequest, parameters: parameters).0
    case .UpdateSession(_, let parameters):
        return Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: parameters).0
    default:
        return mutableURLRequest
    

感谢您的帮助，我正在做测试，需要这个 crud 来实现

【参考方案1】：

确保文件顶部的import Alamofire 正确无误。这为我解决了问题。
