Get cookies from httpwebrequest
提问by Peter
I'm trying to get all cookies from a website using this code
我正在尝试使用此代码从网站获取所有 cookie
CookieContainer cookieJar = new CookieContainer();
var request = (HttpWebRequest)HttpWebRequest.Create("http://www.foetex.dk/ugenstilbud/Pages/Zmags.aspx");
request.CookieContainer = cookieJar;
var response = request.GetResponse();
foreach (Cookie c in cookieJar.GetCookies(request.RequestUri))
{
Console.WriteLine("Cookie['" + c.Name + "']: " + c.Value);
}
Console.ReadLine();
The only thing i want is to display with console.writeline, but im not getting a single of them.
我唯一想要的是用console.writeline 显示，但我没有得到其中的一个。

The following example uses the HttpCookie class and its properties to read a cookie with a specific name.
以下示例使用 HttpCookie 类及其属性读取具有特定名称的 cookie。
HttpCookie myCookie = new HttpCookie("MyTestCookie");
myCookie = Request.Cookies["MyTestCookie"];
// Read the cookie information and display it.
if (myCookie != null)
Response.Write("<p>"+ myCookie.Name + "<p>"+ myCookie.Value);
else
Response.Write("not found");
Retrieve the values in the HttpWebResponse.Cookiesproperty of HttpWebResponse. In this example, the cookies are retrieved and saved to isolated storage:
检索的值HttpWebResponse.Cookies财产HttpWebResponse。在此示例中，cookie 被检索并保存到独立存储中：
private void ReadCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse response = (HttpWebResponse)
request.EndGetResponse(asynchronousResult);
using (IsolatedStorageFile isf =
IsolatedStorageFile.GetUserStoreForSite())
{
using (IsolatedStorageFileStream isfs = isf.OpenFile("CookieExCookies",
FileMode.OpenOrCreate, FileAccess.Write))
{
using (StreamWriter sw = new StreamWriter(isfs))
{
foreach (Cookie cookieValue in response.Cookies)
{
sw.WriteLine("Cookie: " + cookieValue.ToString());
}
sw.Close();
}
}
}
}

//Please use this,
HttpWebRequest request = null;
request = HttpWebRequest.Create(StringURL) as HttpWebRequest;
HttpWebResponse TheRespone = (HttpWebResponse)request.GetResponse();
String setCookieHeader = TheRespone.Headers[HttpResponseHeader.SetCookie];

To get the list of cookies, you can use the below method;
要获取 cookie 列表，您可以使用以下方法；
private async Task<List<Cookie>> GetCookies(string url)
{
var cookieContainer = new CookieContainer();
var uri = new Uri(url);
using (var httpClientHandler = new HttpClientHandler
{
CookieContainer = cookieContainer
})
{
using (var httpClient = new HttpClient(httpClientHandler))
{
await httpClient.GetAsync(uri);
return cookieContainer.GetCookies(uri).Cast<Cookie>().ToList();
}
}
}
