需要在HttpContext的是什么，让FormsAuthentication.SignOut（）来执行？ [英] What is needed in the HttpContext to allow FormsAuthentication.SignOut() to execute?

问题描述

我想写我们注销方法的单元测试。除此之外它 FormsAuthentication.SignOut（）。然而，它抛出一个 System.NullReferenceException 。

I am trying to write a unit test for our log out method. Among other things it FormsAuthentication.SignOut(). However, it throws a System.NullReferenceException.

我创建了一个模拟; 的HttpContext （使用MOQ），但它显然是失去了一些东西。

I've created a mock; HttpContext (using Moq), but it is obviously missing something.

我的模拟上下文包含：

• 接着嘲笑的Htt prequestBase 在请求


• 接着嘲笑的Htt presponseBase 在响应

在 Request.Cookies时
• 使用 HttpCookieCollection ，另一个是关于 Response.Cookies


• 接着嘲笑的IPrincipal 在用户

• A mocked HttpRequestBase on Request
• A mocked HttpResponseBase on Response
• With a HttpCookieCollection on Request.Cookies and another on Response.Cookies
• A mocked IPrincipal on User

的我知道我可以去包装路线，并注入空 FormsAuth 包装对象，在它的地方，但我真的想避免3其他文件只是为了解决code的一条线。这一点，我还是好奇的答案的

I am aware I could go the wrapper route and inject an empty FormsAuth wrapper object in it's place, but I would really like to avoid the 3 additional files just to fix one line of code. That and I am still curious for an answer

所以我的问题是需要在什么的HttpContext 允许 FormsAuthentication.SignOut（）来执行。

So my question is "What is needed in the HttpContext to allow FormsAuthentication.SignOut() to execute."

推荐答案

这里的code为signout。

Here's the code for signout.

public static void SignOut()
{
    Initialize();
    HttpContext current = HttpContext.Current;
    bool flag = current.CookielessHelper.DoesCookieValueExistInOriginal('F');
    current.CookielessHelper.SetCookieValue('F', null);
    if (!CookielessHelperClass.UseCookieless(current, false, CookieMode) || current.Request.Browser.Cookies)
    {
        string str = string.Empty;
        if (current.Request.Browser["supportsEmptyStringInCookieValue"] == "false")
        {
            str = "NoCookie";
        }
        HttpCookie cookie = new HttpCookie(FormsCookieName, str);
        cookie.HttpOnly = true;
        cookie.Path = _FormsCookiePath;
        cookie.Expires = new DateTime(0x7cf, 10, 12);
        cookie.Secure = _RequireSSL;
        if (_CookieDomain != null)
        {
            cookie.Domain = _CookieDomain;
        }
        current.Response.Cookies.RemoveCookie(FormsCookieName);
        current.Response.Cookies.Add(cookie);
    }
    if (flag)
    {
        current.Response.Redirect(GetLoginPage(null), false);
    }
}

看起来像你需要一个CookielessHelperClass实例。太遗憾了，内部的密封 - 有没有办法，除非你使用TypeMock嘲笑它。 +1包装建议：）

Looks like you need a CookielessHelperClass instance. Too bad it's internal and sealed - there's no way to mock it unless you're using TypeMock. +1 for wrapper suggestions :)
