Post data from One Web App (external) to Another Web App hosted in Azure App service

Mathew James 421

Hi Everyone - I am in the process of implementing a payment gateway. Once the transaction is complete, they post the details to our Web page (Webform aspx) hosted in Azure App service. Due to some reason, I am unable to retrieve the data they have Posted in my page. Tried Request.Form ["status"] and I am unable to get any value there. For CORS - I have already added their domain in Allow CORS in App service. Am i missing anything further ? Thanks! -Mathew

We can't see the aspx page that receives the POST and we have no idea how you payment gateway works. Have you tried reaching out to the payment gateway for assistance with their service?

I have already added their domain in Allow CORS in App service.

CORS is browser security and not related to this problem.

Basically its a simple aspx page and it has the following. if (Request.Method == "POST" && Request.Form.Count >0) encResp = Request.Form["encResp"] ; The Problem is its not even getting inside the if loop. So just wondering, do we need to do anything further. The payment Gateway team will POST the data with "encResp" which will have some encrypted text.

I can't reproduce this issue. I built a Web Forms page is it captures a POST without issues.

protected void Page_Load(object sender, EventArgs e)
{
    string encResp = string.Empty;
    if (Request.HttpMethod.ToUpper() == "POST" & Request.Form.Count > 0)
    {
        encResp = Request.Form["encResp"];
    }
}

Hi AgaveJoe - I tried again and its not working. Here is what I have tried.

Created a simple Web Application (WebForms) in Visual Studio (running against .Net Framework 4.7.2)

Created a Simple HTML page called PostData.html

<body> <form id="form1" method="post" action="statusdisplay.aspx"> <div> <input type="text" name="txtPost" value="mytext" /> <input name="Submit1" type="submit" value="submit" /> </div> </form> </body>

Created a Another Page called statusdisplay.aspx to receive the posted data

Upon submitting the data , I tried debugging in statusdisplay.aspx.cs

protected void Page_Load(object sender, EventArgs e) { string test1 = string.Empty; test1 = Request["txtPost"]; if (Request.Form.Count > 0) test1 = Request.Form["txtPost"]; }

I am not receiving the posted data. Always I get null in test1. Please let me know whether I am missing anything ? BTW, both the pages are in same solution now. My Ultimate goal is to get this data in statusdisplay.aspx.cs even when its posted from a different application. Thanks! -Mathew

A better option adding your project to a public GitHub repo so the community has the same code as you.

Hi @Mathew James,

I am not receiving the posted data. Always I get null in test1. Please let me know whether I am missing anything ?

I tested your code and found that the problem is with the Friendly URLs. You can try the following two methods:

Update the form's action to remove the file extension <form id="form1" method="post" action="statusdisplay" >

Amend the configuration for Friendly URLs You will find this in the RouteConfig.cs file in the App_Start folder. The configuration to change is the AutoRedirect mode which by default is set to RedirectMode.Permanent.

public static void RegisterRoutes(RouteCollection routes) { var settings = new FriendlyUrlSettings(); //settings.AutoRedirectMode = RedirectMode.Permanent; routes.EnableFriendlyUrls(settings); }

Best regards,
Lan Huang

Your Suggestion worked.

In fact the Data was posted from HTML page in one site to an aspx page in another site and it worked like a charm.

Note:- When I posted from One aspx in one site to another aspx in another site, it gave an error.

But I am ok for the time being.

Thanks a ton.

Regards
-Mathew
