I have 2 pages I created in ASP.net(C#). The first one(called shoppingcart.asp) has a buy it now button. The second one(called processpay.asp) just waits for google checkout to send an HTTP request to it to process the payment. What I would like to do send a post statement to google checkout with a couple of variables that I want passed back to processpay.asp(ie clientid=3&itemid=10), but I don't know how to format the POST HTTP statement or what settings I have to change in google checkout to make it work.
任何意见将大大AP preciated。
Any ideas would be greatly appreciated.
推荐答案
谷歌Checkout的样品具有code,以及如何将它与任何.NET应用程序集成的教程:
Google Checkout has sample code and a tutorial on how to integrate it with any .NET application:
- Google Checkout API - Google Checkout Sample Code for .NET
请一定要检查标题为:<一个href=\"http://$c$c.google.com/apis/checkout/samples/Google%5FCheckout%5FSample%5F$c$c%5FNET.html#googleCheckoutSample$c$cStepsToIntegrate\"相对=nofollow>集成示例code到你的Web应用程序。
Make sure to check the section titled: "Integrating the Sample Code into your Web Application".
然而,如果你preFER使用服务器端的POST,您可能要检查下列方法,提交一个HTTP POST和返回响应作为一个字符串:
However, if you prefer to use a server-side POST, you may want to check the following method which submits an HTTP post and returns the response as a string:
using System.Net;
string HttpPost (string parameters)
{
WebRequest webRequest = WebRequest.Create("http://checkout.google.com/buttons/checkout.gif?merchant_id=1234567890");
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(parameters);
Stream os = null;
try
{
webRequest.ContentLength = bytes.Length;
os = webRequest.GetRequestStream();
os.Write(bytes, 0, bytes.Length);
}
catch (WebException e)
{
// handle e.Message
}
finally
{
if (os != null)
{
os.Close();
}
}
try
{
// get the response
WebResponse webResponse = webRequest.GetResponse();
if (webResponse == null)
{
return null;
}
StreamReader sr = new StreamReader(webResponse.GetResponseStream());
return sr.ReadToEnd().Trim();
}
catch (WebException e)
{
// handle e.Message
}
return null;
}
参数需要的形式来传递:名1 =值1&放大器; 2 =值2
