爲什麼Response.Cookies是空的？

Question

當我運行這個python腳本

import requests 

main_page_request = requests.get("http://carkit.kg/") 
cookie = main_page_request.cookies.get("csrftoken", "") 

我得到正確的結果，但是當我運行在C＃這樣的代碼：

string url = @"http://carkit.kg"; 

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 

HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 

Debug.Log(response.Cookies["csrftoken"]); // prints "Null" 

它說，response.Cookies是空的。問題是什麼？

Answer 1

您必須向請求添加一個cookie容器。然後它返回cookie：

CookieContainer c = new CookieContainer(); 
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
request.CookieContainer = c; 

HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 

Console.WriteLine(response.Cookies["csrftoken"]); 
// prints "csrftoken=E1iRIi7cQvxvJcnSgOgaEP3XPxTHRUfT"
