Question

У меня есть параметр body, который задает API woocommerce для проверки. При отправке параметра в alamofire я получил код состояния 400.

Я попытался сделать код, как указано выше, но сообщение не работает и отправлятьмне ошибка, которую я отправил выше func postData ()

Я попытался отправить тело Json как код, указанный ниже.

  let baseUrl = "jhkjhkjhkjhkj"
    let header = ["Content-Type": "application/json"]

    func postData() {
    let parameters: [String: AnyObject] = [
        "consumer_key": 
     "***" as AnyObject,
        "consumer_secret":
