Redirect to a PageA using PageA's html?

Whackhead · 02-09-2009 11:15am #1

This may be a strange question, here goes:

I am constructing a post message which is being sent to paypal. I am using this class to achieve this:

http://geekswithblogs.net/rakker/archive/2006/04/21/76044.aspx

This is the code I use to send the post:

            PostSubmitter post = new PostSubmitter();
            post.Url = "https://www.sandbox.paypal.com/cgi-bin/webscr";
            post.PostItems.Add("cmd", "_s-xclick");
            post.PostItems.Add("hosted_button_id", "1054169");
            post.Type = PostSubmitter.PostTypeEnum.Post;
            string result = post.Post();

            Common.DisplayError(result, ref lblErrorMsg);

This is working, my issue though is that I should be getting redirected to the paypal page. Instead I am being sent back the html markup of the page I should be redirecting to, below is the html that I get back in the result string:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>

How can I make it so that I get redirected to the page, instead of getting its markup, or could I use this markup to get to the page?

I was using a form post to achieve this in testing, paypal supplies 'Buy Now' buttons, but IE does not allow nested forms, and I have a form in my master page which must stay, so I have to somehow submit this post without using a form on my page.

Hope this all makes sense

Cheers for any help

Off the top of my head, I don't see anything in the code that would redirect you. It looks like it's doing what it should: executing a post on a remote server and giving you back the results. I think it's effectively screen scraping.

Er, the program works perfectly. The HTML you're getting back is the page. I'm not quite sure what environment you're running this in- if it's some kind of IDE or the command line, just add some more code to save the html to a file and then open that file with a web browser.
EDIT: As Eoin said, this program isn't designed to redirect you, it executes the post and then gives back the html response, which you can use to verify things went smoothly by saving and opening it with a browser.

No, I think he is expecting the browser to go to the page he is getting back - not just render it locally.

He needs to find a way to submit the data from his own form to Paypal.

Try this google search for starters:
http://www.google.ie/search?hl=en&safe=off&client=firefox-a&rls=org.mozilla%3Aen-GB%3Aofficial&hs=PYo&q=aspx+submit+form+to+page+on+different+site&btnG=Search&meta=

You might be able to use JavaScript to change the form action on the client side, but that's not really the most robust method.

Thanks for the replies guys, I have come up with a simpler solution though. My problem was I couldn't have the PayPal 'Buy Now' form on the same page as my master page.

So I added the form to a blank html page, added some script to submit the form on page load. Then on my purchase page I just redirect to this html page and the form is posted and I get redirected. Seems to work ok.

Thanks again

That's pretty much what I suggested last, you're just adding an extra page in the process.

I know it's because of the lifecycle of an ASP.net page, but it would be great if you could just do something like this:

form1.action = "customurl";

You could use Server.Transfer as well, but I think it won't change the address in the title bar.

Redirect to a PageA using PageA's html?
