ios - 如何使用Alamofire上传多张图片？

Question

这是我的 CURL 的样子:

curl -X POST "http://localhost:2202/api/project" -H "accept: aplication/json" -H "key: x" -H "Content-Type: multipart/form-data" -F "project={"title":"Test Title","description":"Test description for new project","priority":false,"category_id":1,"location_id":1}" -F "images[]=@fileName.jpg;type=image/jpeg"

文本上传使用以下代码:

 let parametersText = ["project":["title":requestName.text!,"description":requestDescription.text!,"priority":emergencySwitch.isOn,"category_id":selectedCategoryID,"location_id":selectedLocationID]]

 var selectedImagesForUpload = [Image]()

        Alamofire.upload(multipartFormData: { multipartFormData in
            // Texts
            for (key, value) in parametersText{
                do{
                    let data = try JSONSerialization.data(withJSONObject: value, options: .prettyPrinted)
                    multipartFormData.append(data, withName: key)
                }catch(let err){
                    print(err.localizedDescription)
                }
            }

        },usingThreshold:UInt64.init(),
          to: url,
          method: .post,
          encodingCompletion: { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):
                upload.responseJSON { response in
                    print(response.result.value)
                    sender.isLoading = false
                    self.showNotification(color: #colorLiteral(red: 0.1803921569, green: 0.8, blue: 0.4431372549, alpha: 1), title: "Success", icon: #imageLiteral(resourceName: "UploadSuccess"))
                }
            case .failure(let encodingError):
                print(encodingError)
            }})}

如何更改我的代码以实现多个图像上传？
