我尝试使用 Alamofire Swift 库在多部分请求中将字符串数组发送到服务器，我尝试了几种方法来对数组进行编码，但大部分时间它都作为字符串。谁能帮我这个。除了发送图像上传和其他值的数组对服务器正常。下面是我的代码。

var parameters: Parameters = [

                do {
                    if(key == "VisitedCountries"){
                        let data = try JSONSerialization.data(withJSONObject: self.getVisitedCountryCodeList(), options: [])
                        multipartFormData.append(data, withName: "VisitedCountries" )
                    }
                } catch {
                    print("error msg")
                }
            } else {
                multipartFormData.append((value as! NSString).data(using: String.Encoding.utf8.rawValue)!, withName: key ) …
