ios - 快速的 Alamofire POST 请求

Question

我在我的 swift 2.0 项目中使用了以下代码。虽然我添加了“导入 Alamofire”，但我无法添加 Alamofire.request。我必须创建 Alamofire 对象，然后通过它进行访问。

这就是我创建对象的方式:

let manager = Alamofire.Manager.sharedInstance
manager.request(NSURLRequest(URL: NSURL(string: "http://httpbin.org/get")!))

let parameters = ["foo": "bar"]

manager.request(.POST, "url", parameters: parameters)
.responseJSON { request, response, json, error in
print("request: \(request)")
}

我是 Alamofire 和 swift 的新手。谁能告诉我如何在完成处理程序中从上述代码获得响应，以及为什么我不能使用 Alamofire.request 而不是 manager.request。
