ios - Swift - HTTP 加载失败(通过 alamofire 上传图像时错误代码 : -1005 [4:-4]),。

Question

我是 iOS 新手，使用 Alamofire 上传图片。我写的代码如下:

let image = imageView.image
        let imgData = UIImageJPEGRepresentation(image!, 0.2)!
        let headers: HTTPHeaders = [
            "x-access-token": "######",
            "Accept": "application/json"
        ]
        let parameters = ["profile_picture": "kinza"]
        let url = try! URLRequest(url: URL(string:"######")!, method: .post, headers: headers)

        Alamofire.upload(multipartFormData: { multipartFormData in
            multipartFormData.append(imgData, withName: "profile_picture",fileName: "kinza.jpg", mimeType: "image/jpg")
            for (key, value) in parameters {
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
            }
        },
                         with: url)
        { (result) in
            switch result {
            case .success(let upload, _, _):

                upload.uploadProgress(closure: { (progress) in
                    print("Upload Progress: \(progress.fractionCompleted)")
                })

                upload.responseJSON { response in
                    print(response.result.value)
                }

            case .failure(let encodingError):
                print(encodingError)
            }
        }

当我运行这段代码时，我得到以下日志:

2017-11-07 11:03:21.595826+0500 TestApiProject[2457:51089] [] nw_socket_get_input_frames recvmsg(fd 6, 4096 bytes): [54] Connection reset by peer

Upload Progress: 1.0
nil

它已搜索但没有找到任何特定于“错误代码 -1005”的内容 我该如何解决？我错过了什么吗？

我对此有一些疑问:

• 如果 http 加载失败，那么控制如何转到成功 block Alamofire 请求？
• response.result.value 的值为 nil。我的有问题吗结束还是在服务器端？
• 我是否需要向我的 info.plist 添加更多属性？这是怎么回事目前是。

任何帮助将不胜感激。

试试这个..

let image = imageView.image
        let imgData = UIImageJPEGRepresentation(image, 0.2)!

        let parameters = ["profile_picture": "kinza"]

        Alamofire.upload(multipartFormData: { multipartFormData in
            multipartFormData.append(imgData, withName: "profile_picture",fileName: "kinza.jpg", mimeType: "image/jpg")
            for (key, value) in parameters {
                multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
            }
        },to:"http://YOUR URL"){ (result) in

            switch result {
                case .success(let upload, _, _):

                    upload.uploadProgress(closure: { (progress) in
                        print("Upload Progress: \(progress.fractionCompleted)")
                    })

                    upload.responseJSON { response in
                        print(response.result.value!)
                    }

                case .failure(let encodingError):
                    print(encodingError)
            }
        }

这对我有用..
