Alamofire 4-使用gzip编码上传多部分

import Alamofire

let imageData = UIImage(named: "image.png")!.jpegData(compressionQuality: 0.8)
let multipartFormData = MultipartFormData()
multipartFormData.append(imageData!, withName: "image", fileName: "image.png", mimeType: "image/png")

let parameters: [String: Any] = [
    "key1": "value1",
    "key2": "value2"
]

Alamofire.upload(
    multipartFormData: { multipartFormData in
        for (key, value) in parameters {
            if let data = "\(value)".data(using: .utf8) {
                multipartFormData.append(data, withName: key)
            }
        }
        multipartFormData.append(imageData!, withName: "image", fileName: "image.png", mimeType: "image/png")
    },
    to: "https://example.com/upload",
    headers: ["Content-Encoding": "gzip"],
    encodingCompletion: { encodingResult in
        switch encodingResult {
        case .success(let upload, _, _):
            upload.responseJSON { response in
                // 处理服务器响应
            }
        case .failure(let encodingError):
            // 处理编码错误
        }
    }
)
