如何在 iOS swift 4 中访问 Magento Rest API

Question

我正在将代码写入 post 来自 Magento REST API 的数据，用于 IOS 应用程序让我出错。我尝试使用相同的代码从登录和注册视图控制器得到同样的错误 api Magento REST API 。我成功地从 api 获取数据，但在 api

中获取 post 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 Decoding error: \nUnable to unserialize value... 它指向反序列化 JSON 参数的问题。所以我尝试在 Alamofire 请求上使用编码，URLEncoding.queryString 对我有用。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)
}
