我正在尝试使用C#和HttpClient类在Spotify登录页面上获取cookie。但是,当我知道正在设置cookie时,CookieContainer始终为空。我没有发送任何标头,但是它仍然应该给我cookie,因为当我使用python(请求模块)发送不带任何标头的GET请求时,我得到了csrf令牌。这是我的代码:
using System;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;
using System.Reflection;
using System.Runtime.InteropServices;
using System.Collections;
using System.Web;
class Program
{
static void Main()
{
Task t = new Task(MakeRequest);
t.Start();
Console.WriteLine("Getting cookies!");
Console.ReadLine();
}
static async void MakeRequest()
{
CookieContainer cookies = new CookieContainer();
HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = cookies;
Uri uri = new Uri("https://accounts.spotify.com/en/login/?_locale=en-US&continue=https:%2F%2Fwww.spotify.com%2Fus%2Faccount%2Foverview%2F");
HttpClient client = new HttpClient(handler);
var response = await client.GetAsync(uri);
string res = await response.Content.ReadAsStringAsync();
Console.WriteLine(cookies.Count);
foreach (var cookie in cookies.GetCookies(uri)) {
Console.WriteLine(cookie.ToString());
}
}
}
对我来说,这似乎很简单,但是该程序始终说有0个cookie。有人知道怎么回事吗?

您需要使用HttpClientHandler.UseCookies
Property
public bool UseCookies { get; set; }
获取或设置一个值,该值指示处理程序是否使用CookieContainer属性存储服务器cookie,并在发送请求时使用这些cookie。
//...
CookieContainer cookies = new CookieContainer();
HttpClientHandler handler = new HttpClientHandler();
handler.CookieContainer = cookies;
handler.UseCookies = true; //<-- Enable the use of cookies.
//...

我尝试使用Console.WriteLine(response.Headers)将响应标头写入控制台,并将带有csrf令牌的Set-Cookie标头打印到控制台。因此,看来HttpClient不会将此标头中的cookie视为实际cookie,因此不会将这些cookie添加到CookieContainer中。
