Processing http post requests from outside own website

Hi All

Eventual goal is to receive and process https post message from Worldpay after customer has gone through their payment process. Example worldpay have given of the 'message' from their end is:

POST /fail?installation=205844&msgType=authResult HTTP/1.0Content-Type: application/x-www-form-urlencoded; charset=UTF-8Host: www.worldpay.comContent-Length: 973User-Agent: WJHRO/1.0 (WorldPay Java HTTP Request Object)region=new+format+region&authAmountString=%26%23163%3B10.00&_SP.charEnc=UTF-8&desc=&tel=&address1=new+format+address1&countryMatch=N&cartId=15615166165&address2=new+format+address2&address3=new+format+address3&town=city&region=county&callbackPW=&lang=en&rawAuthCode=A&transStatus=Y&amountString=%26%23163%3B10.00&authCost=10.00&currency=GBP&installation=205844&amount=10.00&wafMerchMessage=waf.warning&countryString=United+Kingdom&displayAddress=new+format+address1%0Anew+format+address2%0Anew+format+address3%0Anew+format+town%0Anew+format+region&transTime=1313762603546&name=AUTHORISED&testMode=0&ipAddress=192.168.90.15&fax=&rawAuthMessage=cardbe.msg.authorised&instId=205844&AVS=2004&compName=BG+Address+change&authAmount=10.00&postcode=postcode&cardType=Visa&cost=10.00&authCurrency=GBP&country=GB&charenc=UTF-8&email=darren.irwin%40test.worldpay.com&address=new+format+address1%0Anew+format+address2%0Anew+format+address3&transId=1300002227&msgType=authResult&town=new+format+town&authMode=A

Anyway I wanted to start with the very basics so I'm trying out a very simple test:

I've put this form in the source plain html page:

<form id="frm_post" action="post_recv.aspx" target="_blank" method="POST" >
<input type="text" id="txtName2″ name="name2″ />
<input type="text" id="txtAddr2″ name="addr2″ />
<input type="submit" value="Send Using Post" />
</form>

And this is the post_recv.aspx page:

<%@ page language="C#" %>
 
<html>
 <head>
 <title>Post: Receiver</title>
 </head>
 <body>
 <table border="2″ cellpadding="7″ cellspacing="2″ >
 <tr>
 <th>Name</th> <th>Address</th>
 </tr>
 <tr>
 <td><% Response.Write(Page.Request.Form["name2"]); %></td>
 <td><% Response.Write(Page.Request.Form["addr2"]); %></td>
 
 </tr>
 </table>
 </body>
 </html>

When I submit the form on the source page it goes to post_recv.aspx but rather than display the values it just shows the source code of post_recv.aspx in browser (everything in the <body> tags)

I'm using webmatrix2 beta and I'm doing this on my localhost. I couldn't find an example in webmatrix so I borrowed the example and c# code from here:

Re: Processing http post requests from outside own website

I also made a cshtml/razor version for testing:

<!DOCTYPE html>

<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title>postsend.html</title>
    </head>
    <body>
        <form action="postreceive.cshtml" method="post">
            <input name="test1" id="test1" type="text">
            <input type="submit">
        </form>
        
    </body>
</html>

and postreceive.cshtml:

@{
var nothing = "nothing";
var testvar = Request.Form["test"];
}



<!DOCTYPE html>

<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title></title>
    </head>
    <body>
@nothing
@testvar        
    </body>
</html>

I get the 'nothing' variable output to page but not 'testvar' which is the post

If somebody could point me in the right direction please that would be really helpful

Thanks

Re: Processing http post requests from outside own website

Oops sorry my cshtml/razor version does work actually (after fixing my typo for textfield name - 'test1' instead of 'test')

Ok so does that mean I'm ok using webpages/razor instead of c# to deal with post message like the one from worldpay in my first post?

Thanks

Re: Processing http post requests from outside own website

I think the problem is:

Page.Request.Form["name"]

The example use

Page.Request.QueryString["name"]

That's absolutely diffrent.

You can use QueryString["name"] get the value "Dino" in this url: www.yoursite.com/page1?name=dino

but you can use Form["name"] to get that, actually, if you have a textbox id=name. You can use Page.Request.Form["name"].ToString();

if it's a postback.

   protected void Button1_Click(object sender, EventArgs e)
        {

//button click will cause a postback.
            string str = Page.Request.Form["Name2"].ToString();
            Response.Write(str);
        }

Hope it helpful.
