Question

我有两个项目，一个是客户端，另一个是API提供者。当我向api提供商发送请求时，请求.Headers.GetCookies（）＆＃39;在客户端部分有值，但在

public class AuthorizationServerProvider : OAuthAuthorizationServerProvider
{
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        var test1 = context.Request.Headers.ToList().FirstOrDefault(h => h.Key == "Cookie");

test1为空并且在

中

public class CustomAuthorizeAttribute : AuthorizeAttribute
{

    public override void OnAuthorization(HttpActionContext actionContext)
    {
          var test2 = actionContext.Request.Headers.GetCookies();

test2为null，这是我发送请求的方式：

[HttpPost]
public ActionResult PostToApiProvider(RequestViewModel requestModel)
{
    var request = new HttpResponseMessage();
    // Here I add cookie header in request for authentification
    if (HttpContext.Request.Cookies.Count != 0)
        {
            var cookieList = new List<string>();
            for (var i = 0; i < Request.Cookies.Count; i++)
            {
                cookieList.Add(Request.Cookies[i].Value);
            }

            request.Headers.Add("Cookie", cookieList);
        }
    var response = client.SendAsync(request).Result;
    var testRequestCookies = request.Headers.GetCookies();
return View("SomeView", model)

request和testRequestCookies（调用api提供程序之前和之后）将有cookie值，请参阅屏幕截图：

CookieObject

如果我可以提供更多代码，请询问。谢谢:)）

这是获取Cookie值的方法

private async Task<string> GetCookieValue(string url, string cookieName)
{
    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);
            var cookie = cookieContainer.GetCookies(uri).Cast<Cookie>().FirstOrDefault(x => x.Name == cookieName);
            return cookie?.Value;
        }
    }
}

GetCookies（）在WebApi Controller中返回null
