swift - 将 [UInt8] 作为数据附加到 alamofire

Question

我正在尝试使用 alamofire 将一些字节上传到服务器，我的代码如下:

let parameters: Parameters = ["data": data]
let headers: HTTPHeaders = ["Content-Type": "application/vnd.awallet-signed-orders-v0"]

    Alamofire.request(query, method: .put,
                      parameters: parameters,
                      encoding: JSONEncoding.default,
                      headers: headers).responseJSON { response in
        print("Request: \(String(describing: response.request))")   // original url request
        print("Response: \(String(describing: response.response))") // http url response
        print("Result: \(response.result)") // response serialization result

        if let json = response.result.value {
            let parsedJSON = try! JSON(parseJSON: (json as! String))
            callback(parsedJSON["orders"]["accepted"])
        }

        if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
            print("Data: \(utf8Text)") // original server data as UTF8 string
        }
    }
}

数据是[UInt8]，但是这样做会使alamofire将字节转换为字符串，如果数组是[0,0]，它就会变成“0,0”，这不是我想要的，因为我想要它直接上传字节。

有没有办法在 alamofire 中做到这一点？

注意:我不想将其转换为十六进制字符串，因为这效率不高

解决了，只需要使用上传方法，将字节转换为数据即可

var hexMessageData = signedOrders[0].message

let headers: HTTPHeaders = ["Content-Type": "application/vnd.awallet-signed-orders-v0"]

Alamofire.upload(Data(bytes: hexMessageData), to: query, method: .put, headers: headers).response { response in
   if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
            print("Data: \(utf8Text)") // original server data as UTF8 string
            callback(data.hexEncoded)
        }
    }
