多部分图像的 ALAMOFIRE 响应图像数据

Question

我写了一个函数，它在服务器上上传两个多部分图像，服务器合并这两个图像并返回一个完整的图像作为响应。

这是函数

func apiObjectInPainting(image: UIImage, maskedimage: UIImage,completion: @escaping (Bool) -> Swift.Void) {
        if let data = UIImageJPEGRepresentation(image,1.0) {
            let filename = getDocumentsDirectory().appendingPathComponent("image1.jpg")
            try? data.write(to: filename)
        }
        if let data = UIImageJPEGRepresentation(maskedimage,1.0) {
            let filename = getDocumentsDirectory().appendingPathComponent("image2.jpg")
            try? data.write(to: filename)
        }

        let fileURL1 = getDocumentsDirectory().appendingPathComponent("image1.jpg")
        let fileURL2 = getDocumentsDirectory().appendingPathComponent("image2.jpg")
        NSLog("Files being stored @\(fileURL1)")

        KVNProgress.show(withStatus: "Replacing Object")

        Alamofire.upload(multipartFormData:{ multipartFormData in
            multipartFormData.append(fileURL1, withName: "image")
            multipartFormData.append(fileURL2, withName: "image")
            multipartFormData.append("SECKEY".data(using: .utf8)!, withName: "Authorization")
        },
                         usingThreshold:UInt64.init(),
                         to:"[URL]",
                         method:.post,
                         encodingCompletion: { encodingResult in
                            switch encodingResult {
                            case .success(let upload, _, _):
                                upload.response { response in
                                    debugPrint(response)
                                    KVNProgress.dismiss()
                                    completion(true)
                                }
                            case .failure(let encodingError):
                                KVNProgress.dismiss()

                                print(encodingError)
                            }
        })

    }

在 encodeCompletion 我有

case .success(let upload, _, _):
      upload.response { response in
            debugPrint(response)
            KVNProgress.dismiss()
            completion(true)
      }

但在我得到的回应中，

请帮助我得到正确的响应，因为目前它没有成功。

您似乎正在上传大量数据，因此您的请求超时。您可以增加超时间隔及其对您的工作。

代码如下：

let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
configuration.timeoutIntervalForResource = 10800 // seconds
configuration.timeoutIntervalForRequest = 10800 // seconds

alamoFireManager = Alamofire.Manager(configuration: configuration)

快乐编码:)
