使用SwiftyJSON解析使用Swift的JSON时遇到问题

无论我做什么,我都无法为变量“videoUploadId”分配来自JSON响应的“video_upload_id”值.我希望我提供足够的信息来获得一些帮助.谢谢

这是代码的一部分

let task = session.dataTaskWithRequest(request,completionHandler: { (data : NSData!,response,error : NSError!) -> Void in
                if (error == nil) {
                    // Success
                    let statusCode = (response as NSHTTPURLResponse).statusCode
                    println("Status Code: (statusCode)rn")

                    println("Response: (response)rn")

                    println("Data: (data)rn")

                    let dataContent = NSString(data: data!,encoding: NSUTF8StringEncoding)!

                    println("UTF8 Data: (dataContent)rn")

                    let json = JSON(dataContent)

                    if let videoUploadId = json["video_upload_id"].int {

                        println("Video Upload ID (Dict: int): (videoUploadId)")
                    }

                    else if let videoUploadId = json["video_upload_id"].string {

                        println("Video Upload ID (Dict: string): (videoUploadId)")
                    }

                    else if let videoUploadId = json[0].int {

                        println("Video Upload ID (Array: int): (videoUploadId)")
                    }

                    else if let videoUploadId = json[0].string {

                        println("Video Upload ID (Array: string): (videoUploadId)")

                    }


                    else {
                        println(json["video_upload_id"].error)
                    }


                }
                else {
                    // Failure
                    println("URL Session Task Failed: %@",error.localizedDescription);
                }
            })
            task.resume()

这是我从我的控制台收到的：

登录响应：HTTP 200
状态代码：201

回复：{URL：https：//// videos / uploads /} {状态代码：201,headers {
连接=“保持活力”;
“内容长度”= 24;

}}

数据：< 7b227669 64656f5f 75706c6f 61645f69 64223a20 3736307d>

UTF8数据：{“video_upload_id”：760}

可选(Error Domain = SwiftyJSONErrorDomain Code = 901“Dictionary [”video_upload_id“]失败,它不是字典”UserInfo = 0x170238620 {NSLocalizedDescription = Dictionary [“video_upload_id”]失败,它不是字典})

从代码和控制台输出中可以看出,我试图以几种不同的方式设置变量,所有这些似乎都失败了.我收到错误“Dictionary [”video_upload_id“]失败,它不是字典”我甚至尝试前置“[”并附加“]”以试图查看它是否是格式化问题.

有线索吗？
