scrape ASIN from amazon URL using javascript

Question

Assuming I have an Amazon product URL like so

http://www.amazon.com/Kindle-Wireless-Reading-Display-Generation/dp/B0015T963C/ref=amb_link_86123711_2?pf_rd_m=ATVP         


        

Answer 1

This may be a simplistic approach, but I have yet to find an error in it using any of the URL's provided in this thread that people say is an issue.

Simply, I take the URL, split it on the "/" to get the discrete parts. Then loop through the contents of the array and bounce them off of the regex. In my case the variable i represents an object that has a property called RawURL to contain the raw url that I am working with and a property called VendorSKU that I am populating.

try
            {
                string[] urlParts = i.RawURL.Split('/');
                Regex regex = new Regex(@"^[A-Z0-9]{10}");

                foreach (string part in urlParts)
                {
                    Match m = regex.Match(part);
                    if (m.Success)
                    {
                        i.VendorSKU = m.Value;
                    }
                }
            }
            catch (Exception) { }

So far, this has worked perfectly.
