Swift 如何使用alamofire上传转换为base64的图像？

我正在使用Alamofire管理我应用程序中的网络 我用于将图像上载到服务器的API需要两个参数，即图像名称和图像数据（base64字符串） 我知道如何使用此代码将图像转换为base64

    class func convertImageToBase64(image: UIImage) -> String {
    let imageData = UIImagePNGRepresentation(image)!
    return imageData.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
}

但我不知道怎么得到图像名？！ 第二，如果我得到了图像名称，如何将图像上传到服务器，有人能解释上传图像的Alamofire代码吗

这是我的API

Web方法：

准材料 { “文件名”：“hydangeas.jpg”， “ImageData”：“base64string” }

注: 文件名：选择照片的文件名 ImageData:Base 64字符串表示Imge字节

提前感谢您

步骤01：

在顶部导入照片库

import Photos

像这样使用UIImagePickerController（）获取图像

var base64Image: String?
var fileName: String?
 override func viewDidLoad() {
        super.viewDidLoad()
        let image = UIImagePickerController()
        image.delegate = self
        image.sourceType = UIImagePickerController.SourceType.photoLibrary

    }
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {

        if let asset = info[UIImagePickerController.InfoKey.phAsset] as? PHAsset {
                if let fileName = (asset.value(forKey: "filename")) as? String {
                    self.fileName = fileName
                }
            }


         base64Image = convertImageToBase64(image: image)

        }

        self.dismiss(animated: true, completion: nil)
    }

func convertImageToBase64(image: UIImage) -> String {
        let imageData = image.pngData()!
        return imageData.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
    }

{ "FileName":"\(fileName)", "ImageData":"\(base64Image)" }

步骤02： 在参数中设置base64Image，如下所示

var base64Image: String?
var fileName: String?
 override func viewDidLoad() {
        super.viewDidLoad()
        let image = UIImagePickerController()
        image.delegate = self
        image.sourceType = UIImagePickerController.SourceType.photoLibrary

    }
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {

        if let asset = info[UIImagePickerController.InfoKey.phAsset] as? PHAsset {
                if let fileName = (asset.value(forKey: "filename")) as? String {
                    self.fileName = fileName
                }
            }


         base64Image = convertImageToBase64(image: image)

        }

        self.dismiss(animated: true, completion: nil)
    }

func convertImageToBase64(image: UIImage) -> String {
        let imageData = image.pngData()!
        return imageData.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
    }

{ "FileName":"\(fileName)", "ImageData":"\(base64Image)" }

但我需要以jpg的形式上传图像我怎么做？尝试你的代码，但出现红色错误->使用未声明的类型“PHAsset”在下面导入UIKit添加导入照片检查此代码在我的项目中工作，在我构建项目时清理构建你的项目我遇到此错误->键入“UIImagePickerController.InfoKey”（又名“NSString”）没有成员“阶段集”
