[英]Redirect with POST parameters in MVC 4 for Payment Gateway Integration
I am trying to do a payment gateway integration using mvc4 in razor. 我正在尝试使用剃刀中的mvc4进行支付网关集成。 In that i need to call a page with prefilled post form. 因为我需要调用带有预填表格的页面。
Using the below method, I am forming the post method form: 使用下面的方法,我正在形成post方法表单:
private static string PreparePOSTForm(string url, System.Collections.Hashtable data) // post form
{
//Set a name for the form
string formID = "PostForm";
//Build the form using the specified data to be posted.
StringBuilder strForm = new StringBuilder();
strForm.Append("<form id=\"" + formID + "\" name=\"" +
formID + "\" action=\"" + url +
"\" method=\"POST\">");
foreach (System.Collections.DictionaryEntry key in data)
{
strForm.Append("<input type=\"hidden\" name=\"" + key.Key +
"\" value=\"" + key.Value + "\">");
}
strForm.Append("</form>");
//Build the JavaScript which will do the Posting operation.
StringBuilder strScript = new StringBuilder();
strScript.Append("<script language='javascript'>");
strScript.Append("var v" + formID + " = document." +
formID + ";");
strScript.Append("v" + formID + ".submit();");
strScript.Append("</script>");
//Return the form and the script concatenated.
//(The order is important, Form then JavaScript)
return strForm.ToString() + strScript.ToString();
}
And in my Controller page I am calling the PreparePostForm
with required parameter and I am receiving the POST request format. 在我的Controller页面中,我使用必需参数调用PreparePostForm
,并且我正在接收POST请求格式。
[HttpPost]
public ActionResult OrderSummary()
{
string request=PreparePOSTForm("payment URL","hashdata required for payment")
return Redirect(request);
}
But while redirecting I am getting below error. 但是在重定向时我的误差低于误差。
Bad Request - Invalid URL 错误请求 - 无效的网址
HTTP Error 400. The request URL is invalid. HTTP错误400.请求URL无效。
I am missing something here to work with POST request. 我在这里错过了一些与POST请求一起工作的东西。 Can someone help me. 有人能帮我吗。
Thanks in advance. 提前致谢。
You cannot post a form by Redirect
method. 您无法通过Redirect
方法发布表单。 You could send generated form string to View
and after that post the form by Javascript
. 您可以将生成的表单字符串发送到View
,然后通过Javascript
发布表单。
public ActionResult OrderSummary()
{
string request=PreparePOSTForm("payment URL","hashdata required for payment")
return View(model:request);
}
and in View of OrderSummary
: 并在OrderSummary
视图中:
@model string
@Html.Raw(Model)
<script>
$(function(){
$('form').submit();
})
</script>
I suggest you to create an Action
with form which receives a Model
in parameters. 我建议你创建一个Action
with form,它在参数中接收Model
。 Then, just pass model when you redirect to this Action
然后,只需在重定向到此Action
时传递模型
[HttpPost]
public ActionResult OrderSummary()
{
return RedirectToAction("OrderForm", new { HashData = hashData });
}
[HttpGet]
public ViewResult OrderForm(string hashData)
{
OrderFormModel model = new OrderFormModel();
model.HashData = hashData;
return View(model);
}
[HttpPost]
public ActionResult OrderForm(OrderFormModel model)
{
if(ModelState.IsValid)
{
// do processing
}
}
You can do it with JavaScript. 你可以用JavaScript做到这一点。
Make a page which does have a html form and submit it through javascript and put your information as input:hidden in the form. 创建一个具有html表单的页面并通过javascript提交并将您的信息作为输入:隐藏在表单中。
This will submit the data to the another place you want. 这会将数据提交到您想要的其他地方。 Doing it in html gave you more control and you doesn't need to write a action like shown in other answer for every redirect in your app. 在html中执行此操作可以为您提供更多控制权,并且您无需为应用中的每个重定向编写其他答案中显示的操作。
