我正在做一个项目，需要一个网站和一个移动应用程序，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，这也将用于网站和移动应用程序。多个子域FormsAuthentication无法使用，使用Web API MVC 4
API的地址是：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在那里使用Cookies。
当用户得到验证它得到200的Http萨特斯与的Set-Cookie头，其中允许域也提到了一起。
这里是请求和响应：

现在根据回应，浏览器应该这个cookie发送到服务器的每个请求到该域domain.com或其任何子域。
但是，这并没有发生，今天早上它怎么会为我工作，但我不知道我做了一个发布后发生了什么。
而且这里更refrence是我使用的设置cookie，并检查用户登录的代码。
这里以用户身份登录，该检查执行中的API，在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，只需根据其角色检查用户身份验证，在web.config中。
<location path="TeacherPanel">
<system.web>
<authorization>
<allow roles="teacher" />
<deny users="?" />
</authorization>
</system.web>
</location>
这些是我发现要检查通过这个问题研究的细节。随意提出任何事情，每一条线索都会有所帮助。在api.domain的web配置
<authentication mode="Forms">
<forms name=".Teacher" loginUrl="Login.aspx" protection="All" path="/" timeout="30" domain=".domain.com" />
</authentication>
验证部分testing.domain.com的web配置
验证部分。

响应由服务器发送：

添加机键和添加到期时间的cookie
进行身份验证POST请求通过浏览器后

任何猜测为什么浏览器不发送Cookie传回？
您还可以发布web.config的部分吗？ API和测试都有web.config吗？如果是这样，你确定机器钥匙匹配吗？ –
explunit
刚刚添加了部分，但不知道machinekey在哪里可以找到以及在哪里插入？ –
添加机器键以回答 – explunit
