如何使用Alamofire上传图片(post)？

func uploadImage(image: UIImage, completion: @escaping (Result<String, Error>) -> Void) {
    guard let imageData = image.jpegData(compressionQuality: 0.5) else {
        completion(.failure(NSError(domain: "", code: -1, userInfo: [NSLocalizedDescriptionKey: "无法转换图片到数据"])))
        return
    }
    
    let url = URL(string: "https://your-api-endpoint.com/upload")!
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.setValue("multipart/form-data; boundary=XXXXXX", forHTTPHeaderField: "Content-Type")
    
    let boundary = "XXXXXX"
    let body = NSMutableData()
    
    body.append("--\(boundary)\r\n".data(using: .utf8)!)
    body.append("Content-Disposition: form-data; name=\"file\"; filename=\"image.jpg\"\r\n".data(using: .utf8)!)
    body.append("Content-Type: image/jpeg\r\n\r\n".data(using: .utf8)!)
    body.append(imageData)
    body.append("\r\n".data(using: .utf8)!)
    
    body.append("--\(boundary)--\r\n".data(using: .utf8)!)
    
    request.httpBody = body as Data
    
    let task = URLSession.shared.dataTask(with: request) { data, response, error in
        if let error = error {
            completion(.failure(error))
            return
        }
        
        guard let data = data, let response = response as? HTTPURLResponse, response.statusCode == 200 else {
            completion(.failure(NSError(domain: "", code: -1, userInfo: [NSLocalizedDescriptionKey: "上传失败"])))
            return
        }
        
        let responseString = String(data: data, encoding: .utf8)
        completion(.success(responseString ?? ""))
    }
    
    task.resume()
}
