¿Cómo puedo obtener las cookies de HttpClientHandler.CookieContainer

Question

Aquí está el código:

public static async Task<string> DownloadPageWithCookiesAsync(string url) 
{ 
    HttpClientHandler handler = new HttpClientHandler(); 
    handler.UseDefaultCredentials = true; 
    handler.AllowAutoRedirect = true; 
    handler.UseCookies = true; 
    handler.CookieContainer = new CookieContainer(); 
    HttpClient client = new HttpClient(handler); 
    HttpResponseMessage response = await client.GetAsync(url); 
    response.EnsureSuccessStatusCode(); 

    string responseBody = response.Content.ReadAsString(); 
    return responseBody; 
} 

después de las carreras client.GetAsync(url);, la handler.CookieContainer contiene 7 cookies. ¿Cómo puedo acceder a ellos?

Answer 1

int loop1, loop2; 
HttpCookieCollection MyCookieColl; 
HttpCookie MyCookie; 

MyCookieColl = Request.Cookies; 

// Capture all cookie names into a string array. 
String[] arr1 = MyCookieColl.AllKeys; 

// Grab individual cookie objects by cookie name. 
for (loop1 = 0; loop1 < arr1.Length; loop1++) 
{ 
    MyCookie = MyCookieColl[arr1[loop1]]; 
    Response.Write("Cookie: " + MyCookie.Name + "<br>"); 
    Response.Write ("Secure:" + MyCookie.Secure + "<br>"); 

    //Grab all values for single cookie into an object array. 
    String[] arr2 = MyCookie.Values.AllKeys; 

    //Loop through cookie Value collection and print all values. 
    for (loop2 = 0; loop2 < arr2.Length; loop2++) 
    { 
     Response.Write("Value" + loop2 + ": " + Server.HtmlEncode(arr2[loop2]) + "<br>"); 
    } 
} 

Answer 2

Utilice el método GetCookies de CookieContainer, especificando el URI para el que desea las cookies. Devuelve una CookieCollection que puede enumerar.

Answer 3

Probar:

CookieCollection cookies = handler.CookieContainer.GetCookies(new Uri(/*Uri that the cookies are associated with*/)); 
for(int i = 0; i < cookies.Count; i++) 
{ 
    Cookie c = cookies[i]; 
    //Do stuff with the cookie. 
} 

También se pueden recorrer la CookieCollection con un bucle foreach, creo.

Answer 4

CookieCollection cookies = handler.CookieContainer.GetCookies(/*blah-blah*/); 
foreach (var cookie in cookies.OfType<System.Net.Cookie>()) 
{ 
    // process cookies 
}
