如何在swift中通过alamofire上传pdf和图片(任何一个选定的)文件

import Alamofire
import SwiftyJSON

func uploadPDFFile() {
    let fileURL = Bundle.main.url(forResource: "example", withExtension: "pdf") // 替换为你的PDF文件名
    
    Alamofire.upload(
        multipartFormData: { multipartFormData in
            if let fileURL = fileURL {
                multipartFormData.append(fileURL, withName: "file", fileName: "example.pdf", mimeType: "application/pdf")
            }
        },
        to: "https://your-upload-url.com",
        method: .post,
        headers: nil,
        encodingCompletion: { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):
                upload.responseJSON { response in
                    if let value = response.result.value {
                        let json = JSON(value)
                        // 处理返回的JSON数据
                    }
                }
            case .failure(let encodingError):
                print(encodingError)
            }
        }
    )
}

uploadPDFFile()

func uploadImageFile() {
    let image = UIImage(named: "example.jpg") // 替换为你的图片文件名
    let imageData = image?.jpegData(compressionQuality: 0.8)
    
    Alamofire.upload(
        multipartFormData: { multipartFormData in
            if let imageData = imageData {
                multipartFormData.append(imageData, withName: "file", fileName: "example.jpg", mimeType: "image/jpeg")

                        let json = JSON(value)
                        // 处理返回的JSON数据
                    }
                }
