C# IHttpHandler将cookie发送回呼叫网站

我有一个订购网站，需要在供应商网站上提出设置请求。 为此，我使用一个WebHanlder（ashx文件）来读取cXML中的安装请求，使用HttpContext对象，该对象工作正常

其中一个要求是，我们返回一个名为“买方Cookie”的Cookie以及一个CXML200OK响应

我遇到的问题是，当我在context.Response中创建cookie时，当我执行

Response.Output.Write（）。

我尝试在写入后使用

response.Flush（）

，但仍然不起作用

如何将cookie发送回呼叫站点

这是我的密码：

订购网站

Stream stream = null;
byte[] bytes = Encoding.ASCII.GetBytes(File.ReadAllText(@"D:\Prototypes\HTTPPost\cXMLFiles\PunchOutSetupRequest.xml"));
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://localhost:45454/PunchOutRequest.ashx");

webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
webRequest.ContentLength = bytes.Length;

try
{
    stream = webRequest.GetRequestStream();
    stream.Write(bytes, 0, bytes.Length);
}
catch (Exception)
{
    throw;
}
finally
{
    if (stream != null)
        stream.Close();
}

HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader responseReader = new StreamReader(responseStream);

string r = responseReader.ReadToEnd();
var buy = webRequest.CookieContainer;
var buyer = response.Cookies["BuyerCookie"]; // This is always null

var request = context.Request;
StreamReader reader = new StreamReader(request.InputStream);

string text = reader.ReadToEnd();

POSetup setup = new POSetup();

if (setup.IsSetupRequestValid(text))
{
    HttpCookie cookie = new HttpCookie("BuyerCookie", "100");

    context.Response.Cookies.Add(cookie);
    context.Response.Output.Write(setup.GetOKResponse());
}

供应商站点

Stream stream = null;
byte[] bytes = Encoding.ASCII.GetBytes(File.ReadAllText(@"D:\Prototypes\HTTPPost\cXMLFiles\PunchOutSetupRequest.xml"));
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://localhost:45454/PunchOutRequest.ashx");

webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
webRequest.ContentLength = bytes.Length;

try
{
    stream = webRequest.GetRequestStream();
    stream.Write(bytes, 0, bytes.Length);
}
catch (Exception)
{
    throw;
}
finally
{
    if (stream != null)
        stream.Close();
}

HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader responseReader = new StreamReader(responseStream);

string r = responseReader.ReadToEnd();
var buy = webRequest.CookieContainer;
var buyer = response.Cookies["BuyerCookie"]; // This is always null

var request = context.Request;
StreamReader reader = new StreamReader(request.InputStream);

string text = reader.ReadToEnd();

POSetup setup = new POSetup();

if (setup.IsSetupRequestValid(text))
{
    HttpCookie cookie = new HttpCookie("BuyerCookie", "100");

    context.Response.Cookies.Add(cookie);
    context.Response.Output.Write(setup.GetOKResponse());
}

尝试添加以下行：

webRequest.CookieContainer = new CookieContainer();

紧接着

webRequest.ContentLength = bytes.Length;
