I am trying to do a payment gateway integration using mvc4 in razor. In that i need to call a page with prefilled post form.
Using the below method, I am forming the post method form:
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.
[HttpPost]
public ActionResult OrderSummary()
{
string request=PreparePOSTForm("payment URL","hashdata required for payment")
return Redirect(request);
}
But while redirecting I am getting below error.
Bad Request - Invalid URL
HTTP Error 400. The request URL is invalid.
I am missing something here to work with POST request. Can someone help me.
Thanks in advance.
