swift - Swift 中的 HTTP POST 请求

Question

如何在 iOS 上发布请求？实际上，当我登录 Facebook 时，它会从登录位置(纬度、经度)获取用户信息，例如用户名。是否可以使用api 链接:http://buddysin.aumkiiyo.com/fbc

我的代码是:

@IBAction func btnAPI(sender: UIButton)
{
    //startConnection()
    connectToWebAPI()
}
func connectToWebAPI()
{ 
    //setting up the base64-encoded credentials
    let id = "1620912344817986"
    //let password = "pass"
    let loginString = NSString(format: "%@:%@", id)
    let loginData: NSData = loginString.dataUsingEncoding(NSUTF8StringEncoding)!
    let base64LoginString = loginData.base64EncodedStringWithOptions(nil)

    //creating the requestz
    let url = NSURL(string: "http://buddysin.aumkiiyo.com/fbc")
    var request = NSMutableURLRequest(URL: url!)
    let config = NSURLSessionConfiguration.defaultSessionConfiguration()
    let session = NSURLSession.sharedSession()
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    let urlConnection = NSURLConnection(request: request, delegate: self)
    request.HTTPMethod = "POST"
    request.setValue(base64LoginString, forHTTPHeaderField: "Authorization")

    let task = session.dataTaskWithURL(url!, completionHandler: {data, response, error -> Void in
        if (error != nil) {
            println(error)
        }
        else {
            // converting the data into Dictionary
            var error: NSError?
            let jsonResult = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &error) as! NSDictionary

            println(jsonResult)
        }
    })

    //fire off the request  

    task.resume()
}

当我运行时， fatal error 显示为

`fatal error: unexpectedly found nil while unwrapping an Optional value`

在“jsonResult”中

我认为最好使用Alomafire 。就像 Objective-C 中的 AFNetWorking 一样，它是一个简化了很多 http 请求的库。
