如何以UTF-8格式FROM Rest模板发送MULTIPART_FORM_DATA

Question

   let url = URL(string: "https://min-api.cryptocompare.com/data/all/exchanges")! //change the url

    //create the session object
    let session = URLSession.shared

    //now create the URLRequest object using the url object
    let request = URLRequest(url: url)

    //create dataTask using the session object to send data to the server
    let task = session.dataTask(with: request as URLRequest, completionHandler: { data, response, error in

        guard error == nil else {
            return
        }

        guard let data = data else {
            return
        }

        do {
            //create json object from data
            if var json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String: Any] {
                if (!json.isEmpty) {
                    print(json)

                }

            }
        } catch let error {
            print(error.localizedDescription)
        }
    })
    task.resume()
