如何在iOS swift 4中访问Magento Rest API

我正在编写代码来发布来自Magento REST API的数据，用于IOS应用程序put get me错误。我尝试从登录和注册视图控制器在相同的代码得到我相同的错误 api Magento REST api。我成功地从api获取数据，但在api中发布数据时出错

    self.internetConnectionChecker { (status) in
    if status{
    KVNProgress.show();
    let userLoginApi = "http://3.85.198.62/4apps/rest/V1/integration/customer/token"
                    let parameters: Parameters = ["username": username, "password": password]
                    let header : HTTPHeaders = ["Content-Type": "application/json"]
                    Alamofire.request(userLoginApi, method: .post, parameters: parameters,  headers: header).responseObject {  (response: DataResponse<User>) in
                        KVNProgress.dismiss()
                         print(response.request?.url)
                        print(response.request?.allHTTPHeaderFields)
                        let json = try! JSONSerialization.jsonObject(with: response.data!, options: JSONSerialization.ReadingOptions.mutableContainers)
                        print(json)
                            DispatchQueue.main.async {
                                loginCallback(response.result.value!)}
                            self.maincontroller.SuccessMessage(title: "تسجيل الدخول", successbody: "")

The Output

您看到的错误发生在Magento端

解码错误：\n无法取消序列化值…

它指出了取消序列化JSON参数的问题。因此，我尝试对Alamofire请求和

URLEncoding进行编码。queryString

适合我。这是我的代码

Alamofire.request(userLoginApi, method: .post, parameters: parameters, encoding: URLEncoding.queryString, headers: header).responseData {  (response: DataResponse<Data>) in
    let json = try! JSONSerialization.jsonObject(with: response.data!, options: JSONSerialization.ReadingOptions.mutableContainers)
    print("json", json)
}

Alamofire.request（userLoginApi，方法：.post，参数：参数，编码：URLEncoding.queryString，头：头）。响应数据{（响应：DataResponse）在
让json=try！JSONSerialization.jsonObject（带有：response.data！，选项：JSONSerialization.ReadingOptions.mutableContainers）
打印（“json”，json）
