我正在做一个需要网站和移动应用程序的项目，几乎具有相同的功能。因此，为此我正在使用Asp.net Web API构建 API ，它也将用于网站和移动应用程序。
API地址是：api.domain.com 网站地址是：testing.domain.com
问题：
现在在 api.domain.com，我允许用户登录，FormsAuthentication在那里与Cookies一起使用。
当用户通过身份验证时，它会获得200 个 Http Satus以及Set-Cookie Header，其中还提到了允许的域。
这是请求和响应：

现在根据响应，浏览器应该将此 cookie 发送到服务器，并将每个请求发送到此域domain.com或其任何子域。
但这并没有发生，今天早上它对我有用，但我不知道发布后发生了什么。
另外为了更多参考，这里是我用来设置 cookie 并检查用户是否登录的代码。
此处为登录用户，此检查在 API 中执行，位于 api.domain.com。
[AllowAnonymous]
[HttpPost]
public HttpResponseMessage Login(LoginModel model, string returnUrl)
{
if (ModelState.IsValid)
{
Teacher t;
if (Teacher.Login(model.UserName,model.Password,out t))
{
// Roles.AddUserToRole(t.ID.ToString(), "teacher");
FormsAuthentication.SetAuthCookie(t.ID.ToString(), model.RememberMe);
FormsAuthenticationTicket ft = new FormsAuthenticationTicket(
1, // version
t.ID.ToString(), // get username from the form
DateTime.Now, // issue time is now
DateTime.Now.AddMinutes(30), // expires in 10 minutes
true, // cookie is not persistent
"teacher" // role assignment is stored
// in userData
);
string enTicket = FormsAuthentication.Encrypt(ft);
HttpResponseMessage res = Request.CreateResponse(HttpStatusCode.OK);
System.Net.Http.Headers.CookieHeaderValue cokie = new System.Net.Http.Headers.CookieHeaderValue(FormsAuthentication.FormsCookieName, enTicket);
cokie.Domain = "domain.com .domain.com";
IEnumerable<System.Net.Http.Headers.CookieHeaderValue> cookies = new System.Net.Http.Headers.CookieHeaderValue[] { cokie };
res.Headers.AddCookies(cookies);
return res;
}
return Request.CreateResponse(HttpStatusCode.Unauthorized);
}
// If we got this far, something failed, redisplay form
return Request.CreateResponse(HttpStatusCode.Unauthorized);
}
现在在 testing.domain.com，只需在 web.config 中根据其角色检查用户的身份验证。
<location path="TeacherPanel">
<system.web>
<authorization>
<allow roles="teacher" />
<deny users="?" />
</authorization>
</system.web>
</location>
这些是我发现通过这个问题进行研究的细节。随意提出任何建议，每条线索都会有所帮助。
testing.domain.com 的 Web 配置中的身份验证部分
<authentication mode="Forms">
<forms name=".Teacher" loginUrl="Login.aspx" protection="All" path="/" timeout="30" domain=".domain.com" />
</authentication>
api.domain.com 的 Web 配置中的身份验证部分
<authentication mode="Forms">
<forms name=".Teacher"
cookieless="UseCookies"
requireSSL="false"
domain=".domain.com"
/>
</authentication>
添加机器密钥并将过期时间添加到 Cookie 后
通过浏览器发布请求以进行身份验证：

服务器发送的响应：

接下来获取发送到 testing.domain.com 的请求以进行测试（由于浏览器未将 cookie 发送回服务器而失败）：
GET / HTTP/1.1
Host: testing.domain.com
Connection: keep-alive
X-Requested-With: XMLHttpRequest
User-Agent: Mozilla/5.0 (Windows NT 6.2) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1

猜猜为什么浏览器不发回 Cookie？
