asp.net之如何在 ASP.Net 中保存数据后获得 Json 响应

创建数据后如何获得响应？所以我想要的是什么时候保存。它显示它的响应，也许在消息框中？可以吗？

这是我保存的 Controller 代码..

 [HttpPost] 
  [ValidateAntiForgeryToken] 
  public async System.Threading.Tasks.Task<ActionResult> Create(FormCollection formCollection, string fn, string ln , ParentModel apsp) 
    { 
         string username = "sa"; 
         string apiKey = "sa"; 
         string baseUrl = "https://sandbox-api.paysimple.com"; 
         var settings = new PaySimpleSdk.Models.PaySimpleSettings(apiKey, username, baseUrl); 
 
         var paymentService = new PaymentService(settings); 
 
 
        fn = apsp.Customer.FirstName; 
        ln = apsp.Customer.LastName; 
        string street1 = apsp.Customer.BillingAddress.StreetAddress1; 
        string street2 = apsp.Customer.BillingAddress.StreetAddress2; 
        string city = apsp.Customer.BillingAddress.City; 
        Enum statecode = apsp.Customer.BillingAddress.StateCode; 
        Enum country = apsp.Customer.BillingAddress.Country; 
        string zipcode = apsp.Customer.BillingAddress.ZipCode; 
 
        string credit = apsp.CreditCard.CreditCardNumber; 
        string expir = apsp.CreditCard.ExpirationDate; 
        Enum issuer = apsp.CreditCard.Issuer; 
 
        decimal amount = apsp.Payment.Amount; 
        string ccv = apsp.Payment.Cvv; 
 
        var customerPayment = new NewCustomerPayment<CreditCard> 
        {                              
           Customer = new Customer() 
             { 
                    FirstName = fn, 
                    LastName = ln, 
                    BillingAddress = new Address 
                    { 
                        StreetAddress1 = street1, 
                        StreetAddress2 = street2, 
                        City = city, 
                        StateCode = (StateCode)statecode, 
                        Country = (CountryCode)country, 
                        ZipCode = zipcode 
                    } 
             }, 
           Account = new CreditCard 
             { 
                    CreditCardNumber = credit, 
                    ExpirationDate = expir, 
                    Issuer = (Issuer)issuer 
             }, 
            Payment = new Payment 
             { 
                    Amount = amount, 
                    Cvv = ccv 
              } 
        }; 
 
        var newCustomerPayment = await     paymentService.CreateNewCustomerPaymentAsync(customerPayment); 
 
        return RedirectToAction("Index"); 
 
        } 

创建数据的函数来自SDK和模型本身

请您参考如下方法:

你有两个选择:

1. 创建操作应该返回 JsonResult 而不是重定向。但是在调用 Create 操作时需要使用 AJAX。:

   public async System.Threading.Tasks.Task<ActionResult> Create(FormCollection formCollection, string fn, string ln , ParentModel apsp) 
   { 
      /// your code for creating object 
      return Json(newCustomerPayment, JsonRequestBehavior.AllowGet); 
   } 
   

   在客户端使用 Ajax.BeginForm 而不是 Html.BeginForm

   using (Ajax.BeginForm("Create", Home , new AjaxOptions { HttpMethod = "POST", OnSuccess = "customerPaymentCreatedSuccess" })) 
   { 
   } 
    
   <script> 
       function customerPaymentCreatedSuccess(response) 
       { 
           alert(JSON.stringify(response, null, 4)); 
       } 
   </script> 
   

2. 使用 Post/Redirect/Get 模式。创建新付款后，将其存储在 TempData 中 并像现在一样返回重定向:

   TempData["newCustomerPayment"] = newCustomerPayment;  
   return RedirectToAction("Index"); 
   

   然后在 Index Action 中检查 TempData 中是否有任何内容，如果有，则将其传递给 View

   public ActionResult Index() 
   { 
       var customerPayment = TempData["newCustomerPayment"] as NewCustomerPayment; 
       if(customerPayment != null) 
       { 
          ViewBag.customerPayment = customerPayment;  
       } 
       //other code.. 
   

索引 View - 生成 JavaScript 代码以显示 customerPayment:

@{var customerPayment = ViewBag.customerPayment as NewCustomerPayment;} 
@if(customerPayment  != null) 
{ 
    <script> 
        alert("@Html.Raw(JsonConvert.SerializeObject(customerPayment ))"); 
   </script> 
}
