Question

我目前正在尝试使用Github上的Finjinon sdk发送多张照片，以便能够拍摄多张照片并将其发送到我的服务器。我正在使用alamofire SDK处理实际图片的发送。但是，每次发送图片时，它会随机复制其中一张图片，然后发送其余的图片。老实说，我完全陷入了困境，我什至不知道从哪里开始解决这个问题。

  for i in 0..<imageResultsFilter.count {
            print(i)
            let imageForUpload = imageResultsFilter[i]
            if let imageData = UIImageJPEGRepresentation(imageForUpload, 1) {
                multipartFormData.append(imageData, withName: "file\(i)", fileName:"image\(i).jpeg", mimeType: "image/jpeg")
            }
        }

这是我的for循环，我已经检查了它，我相当肯定这不是问题。

这就是我将图片发送到服务器的方式

  // Uploading files to server using Alamofire.
    Alamofire.upload(multipartFormData: {
        multipartFormData in

        for (key, parValue) in parameters {
            multipartFormData.append((parValue.data(using: .utf8))!, withName: key)
        }

        var imageResultsFilter = [UIImage]()
        imageResultsFilter = self.imageArray.enumerated().filter({ index, _ in
            index % 2 != 0
        }).map({ $0.1 })

        print(self.imageArray.count)

        for i in 0..<imageResultsFilter.count {
            print(i)
            let imageForUpload = imageResultsFilter[i]
            if let imageData = UIImageJPEGRepresentation(imageForUpload, 1) {
                multipartFormData.append(imageData, withName: "file\(i)", fileName:"image\(i).jpeg", mimeType: "image/jpeg")
            }
        }

    }, to: urlPath, encodingCompletion: {
        encodingResult in
        switch encodingResult {
        case .success(let upload, _, _) :
            upload.responseJSON(completionHandler: {
                response in

                // Json response from the server
                if let jsonValue = response.result.value {
                    let json = JSON(jsonValue)
                    // Parsing the response from the server
                    for (keyTitle, info) in json {
                        self.alertTitle = "\(keyTitle)"
                        self.messageText = "\(info)"
                    }
                }

                if response.response?.statusCode == 500 {
                    // Alerts user that there was an Error in uploading the file.
                    let alert = UIAlertController(title: self.alertTitle, message: self.messageText, preferredStyle: .alert)
                    alert.addAction(UIAlertAction(title: "Okay", style: .cancel, handler: nil))
                    self.present(alert, animated: true, completion: nil)
                } else if response.response?.statusCode == 200 {
                    // Alerts the user that the file succesfully uploaded to server.
                    let alert = UIAlertController(title: self.alertTitle, message: self.messageText, preferredStyle: .alert)
                    alert.addAction(UIAlertAction(title: "Okay", style: .cancel, handler: nil))
                    self.present(alert, animated: true, completion: nil)
                }

            })
        case .failure(let encodingError):
            print("error:\(encodingError)")
        }
    })
}

老实说，我不知道哪里出了问题。它不会给我任何错误，我使用for循环，因为每次拍照时，它实际上同时存储两个。例如，假设我拍了3张照片。数组将以0-5填充，我将发送其他所有图片。但是，当我回去再拍一张照片时，它将从0-5变为0-7。

使用Finjinon发送照片
