HttpClient发送额外的Cookie

问题描述

运行UWP应用*

所以我有一个HttpClient及其关联的处理程序。我正在向网站发出请求，传入指定的标头，并使用指定的CookieContainer，该Cookie在请求开始时为空。

So I have an HttpClient and it's associated handler. I am making a request to a website, passing in specified headers, and using a specified CookieContainer, which is empty at the beginning of the request.

当我发送请求时，Fiddler显示正在发送的其他我尚未添加的cookie。他们来自哪里？

When I send the request, Fiddler shows extra cookies being sent that I have not added. Where are they coming from?

CookieContainer cookieJar = new CookieContainer();
HttpClientHandler handler = new HttpClientHandler( );
handler.UseDefaultCredentials = false;
handler.CookieContainer = cookieJar;
handler.Proxy = null;
using (var client = new HttpClient(handler as HttpClientHandler))
{
    HttpResponseMessage response = new HttpResponseMessage();
    String loginUrl = Const.BUNGIE_LOGIN_URI + (provider == Const.XBOX_PLATFORM ? Const.XBOX_LOGIN : Const.PS_LOGIN);
    client.BaseAddress = new Uri(loginUrl);
    //client.Timeout = new TimeSpan(0, 0, 0, 0, 450);
    client.DefaultRequestHeaders.Add("Referer", "http://www.bungie.net");
    client.DefaultRequestHeaders.Add("User-Agent", Const.USERAGENT);
    client.DefaultRequestHeaders.Add("X-API-Key", Const.X_API_KEY);
    client.DefaultRequestHeaders.Add("Connection", "Keep-Alive");
    client.DefaultRequestHeaders.Add("Accept", "application/json");
    client.DefaultRequestHeaders.Add("Accept-Language", "en-GB,en-US;q=0.8,en;q=0.6");
    handler.AutomaticDecompression = DecompressionMethods.GZip;

    response = client.GetAsync("").Result;
    response.ReadCookies(); //adds cookies to cookieJar
 }

现在，作为关联的 CookieContainer 为空，这些cookie来自何处？他们可以到达吗？如果我想从中获得价值，我将如何获得它们？

Now, as the associated CookieContainer is empty before the request is made, where are these cookies coming from? Are they accessible? If I wanted the values from them, how would I obtain them?

编辑：它们是从哪里添加到我的HttpClient请求中的？ HttpClient是否具有通用的CookieContainer /缓存？我有两个单独的HttpClient实例，当客户端（A）发出请求时，它收到一个 set-cookie标头，并设置了一个乱七八糟的cookie。

Where are they being added to my HttpClient request from? Does HttpClient have a common CookieContainer / cache? I have two separate HttpClient instances, and when Client (A) makes a request, it received a "set-cookie" header back, setting a "bungled" cookie.

稍后，作为HttpClient的一个单独实例，客户端（B）向同一网站发出请求，并发送客户端（A）中设置的cookie。

Later on, a separate instance of HttpClient, Client (B), makes a request to the same website, sending the cookie set within Client (A).

我没有将此Cookie明确附加到客户（B）的请求中，如何添加它？

I did not explicitly append this cookie to Client (B)'s request, so how is it being added?

推荐答案

在Windows 10内部版本10240上， System.Net.Http.HttpClient 是 Windows.Web.Http.HttpClient （），因此，cookies现在的工作方式略有不同。

On Windows 10 build 10240, System.Net.Http.HttpClient is a wrapper on top of Windows.Web.Http.HttpClient (more info here), and so, cookies now work little bit different.

要删除这些多余的cookie，您将需要使用 HttpCookieManager 删除cookie：

To delete those extra cookies, you will need to delete the cookies using a HttpCookieManager:

HttpBaseProtocolFilter filter = new HttpBaseProtocolFilter();
HttpCookieManager cookieManager = filter.CookieManager;
foreach (HttpCookie cookie in cookieManager.GetCookies(uri))
{
    cookieManager.DeleteCookie();
}
