Asp.net mvc Request.GetOwinContext在单元测试中返回null-如何在单元测试中测试OWIN身份验证?
我目前正在尝试对一个新的WebAPI项目的身份验证进行单元测试,我正在编写一个使用OWIN进行身份验证的项目,但在单元测试上下文中运行它时遇到问题 这是我的测试方法:Asp.net mvc Request.GetOwinContext在单元测试中返回null-如何在单元测试中测试OWIN身份验证?,asp.net-mvc,unit-testing,authentication,asp.net-web-api,owin,Asp.net Mvc,Unit Testing,Authentication,Asp.net Web Api,Owin,我目前正在尝试对一个新的WebAPI项目的身份验证进行单元测试,我正在编写一个使用OWIN进行身份验证的项目,但在单元测试上下文中运行它时遇到问题 这是我的测试方法: [TestMethod] public void TestRegister() { using (WebApp.Start<Startup>("localhost/myAPI")) using (AccountController ac = new AccountController()
[TestMethod]
public void TestRegister()
{
using (WebApp.Start<Startup>("localhost/myAPI"))
using (AccountController ac = new AccountController()
{
Request = new System.Net.Http.HttpRequestMessage
(HttpMethod.Post, "http://localhost/myAPI/api/Account/Register")
})
{
var result = ac.Register(new Models.RegisterBindingModel()
{
Email = "testemail@testemail.com",
Password = "Pass@word1",
ConfirmPassword = "Pass@word1"
}).Result;
Assert.IsNotNull(result);
}
}
我已通过调试确认正在调用我的Startup
方法,调用ConfigurAuth
:
public void ConfigureAuth(IAppBuilder app)
{
HttpConfiguration config = new HttpConfiguration();
config.MapHttpAttributeRoutes();
app.UseWebApi(config);
// Configure the db context and user manager to use a single
// instance per request
app.CreatePerOwinContext(ApplicationDbContext.Create);
app.CreatePerOwinContext<ApplicationUserManager>
(ApplicationUserManager.Create);
// Enable the application to use a cookie to store information for
// the signed in user
// and to use a cookie to temporarily store information about a
// user logging in with a third party login provider
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
// Configure the application for OAuth based flow
PublicClientId = "self";
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/Token"),
Provider = new ApplicationOAuthProvider(PublicClientId),
AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
AllowInsecureHttp = true
};
// Enable the application to use bearer tokens to authenticate users
app.UseOAuthBearerTokens(OAuthOptions);
}
它在以下情况下失败:
return _userManager ?? Request.GetOwinContext()
.GetUserManager<ApplicationUserManager>();
return\u userManager??Request.GetOwinContext()
.GetUserManager();
使用NullReferenceException
-请求。GetOwinContext
正在返回null
所以我的问题是:我是不是走错路了?我应该只是测试JSON响应吗?或者是否有一种“内部”测试OWIN身份验证的好方法?您可以在AccountController的构造函数中传入UserManager,这样它就不会试图在OWIN文本中找到它。默认构造函数对单元测试不友好。我倾向于使用用户管理器工厂注入AccountController。这样,您就可以轻松地交换测试中使用的用户管理器实例。默认工厂可以在构造函数中接受请求,以继续提供用户管理器的每个请求实例。您的测试工厂只返回您希望为测试提供的用户管理器的实例,我通常选择一个实例,它获取一个IUserStore的存根实例,这样就不会对用于存储身份信息的后端产生硬依赖 工厂接口和类:
public interface IUserManagerFactory<TUser>
where TUser : class, global::Microsoft.AspNet.Identity.IUser<string>
{
UserManager<TUser> Create();
}
public class UserManagerFactory : IUserManagerFactory<AppUser>
{
private HttpRequestMessage request;
public UserManagerFactory(HttpRequestMessage request)
{
if (request == null)
{
throw new ArgumentNullException("request");
}
this.request = request;
}
public UserManager<AppUser, string> Create()
{
return request.GetOwinContext().GetUserManager<UserManager<AppUser>>();
}
}
公共接口IUserManagerFactory
其中TUser:class,global::Microsoft.AspNet.Identity.IUser
{
UserManager创建();
}
公共类UserManagerFactory:IUserManagerFactory
{
私有HttpRequestMessage请求;
公共用户管理器工厂(HttpRequestMessage请求)
{
if(请求==null)
{

}

}
公共用户管理器创建()
{
返回请求.GetOwinContext().GetUserManager();
}
}
会计控制员:
public AccountController(IUserManagerFactory<AppUser> userManagerFactory)
{
this.userManagerFactory = userManagerFactory;
}
private UserManager<AppUser> userManager;
public UserManager<AppUser> UserManager
{
get
{
if (this.userManager == null)
{
this.userManager = this.userManagerFactory.Create();
}
return this.userManager;
}
}

公共用户管理器用户管理器

{
if(this.userManager==null)
{
this.userManager=this.userManagerFactory.Create();
}
返回这个.userManager;
}
}
测试工厂:
public class TestUserManagerFactory : IUserManagerFactory<AppUser>
{
private IUserStore<AppUser> userStore;
public TestUserManagerFactory()
{
this.userStore = new MockUserStore();
}
public UserManager<AppUser> Create()
{
return new UserManager<AppUser>(new MockUserStore());
}
}

}
公共用户管理器创建()
{
返回新的UserManager(newmockuserstore());
}
}
要确保在测试期间OWIN上下文可用(即,在调用Request.GetOwinContext()
时修复空引用异常),您需要在测试项目中安装Microsoft.AspNet.WebApi.OWIN
NuGet包。安装后,您可以根据请求使用SetOwinContext
扩展方法
例如:
var controller = new MyController();
controller.Request = new HttpRequestMessage(HttpMethod.Post,
new Uri("api/data/validate", UriKind.Relative)
);
controller.Request.SetOwinContext(new OwinContext());
看
话虽如此,我同意针对特定用例的其他答案——在构造函数中提供AppApplicationUserManager实例或工厂。如果您需要直接与测试将使用的上下文进行交互,则必须执行上面的
SetOwinContext
步骤。GetOwinContext调用context.getowinconvironment();
那是
私有静态IDictionary GetowinenEnvironment(此HttpContextBase上下文)
{
返回(IDictionary)context.Items[HttpContextItemKeys.OwinEnvironmentKey];
}
HttpContextItemKeys.owinenEnvironmentKey是一个常量“owin.Environment”
因此,如果您将其添加到httpcontext的项中,它将起作用
var request = new HttpRequest("", "http://google.com", "rUrl=http://www.google.com")
{
ContentEncoding = Encoding.UTF8 //UrlDecode needs this to be set
};
var ctx = new HttpContext(request, new HttpResponse(new StringWriter()));
//Session need to be set
var sessionContainer = new HttpSessionStateContainer("id", new SessionStateItemCollection(),
new HttpStaticObjectsCollection(), 10, true,
HttpCookieMode.AutoDetect,
SessionStateMode.InProc, false);
//this adds aspnet session
ctx.Items["AspSession"] = typeof(HttpSessionState).GetConstructor(
BindingFlags.NonPublic | BindingFlags.Instance,
null, CallingConventions.Standard,
new[] { typeof(HttpSessionStateContainer) },
null)
.Invoke(new object[] { sessionContainer });
var data = new Dictionary<string, object>()
{
{"a", "b"} // fake whatever you need here.
};
ctx.Items["owin.Environment"] = data;
var请求=新的HttpRequest(“,”http://google.com“,”鲁尔=http://www.google.com")
{
ContentEncoding=Encoding.UTF8//UrlDecode需要设置此选项
};
var ctx=新的HttpContext(请求,新的HttpResponse(新的StringWriter());
//需要设置会话
var sessionContainer=new HttpSessionStateContainer(“id”,new SessionStateItemCollection(),
新的HttpStaticObjectsCollection(),10,true,
HttpCookieMode.AutoDetect,
SessionStateMode.InProc,false);
//这将添加aspnet会话
ctx.Items[“AspSession”]=typeof(HttpSessionState).GetConstructor(
BindingFlags.NonPublic | BindingFlags.Instance,
空,调用约定。标准,
新[]{typeof(HttpSessionStateContainer)},
空)
.Invoke(新对象[]{sessionContainer});
var data=newdictionary()
{
{“a”,“b”}//在这里伪造你需要的任何东西。
};
ctx.Items[“owin.Environment”]=数据;
var data=new Dictionary()
{
{“a”,“b”}//在这里伪造你需要的任何东西。
};
ctx.Items[“owin.Environment”]=数据;
使用这段代码并将其添加到HttpContext而不是ctx,单元测试非常有效。这里的答案很有帮助,但并没有让我完全理解,下面是一个完整的示例:
var userStore = new Mock<IUserStore<User>>();
var appUserMgrMock = new Mock<ApplicationUserManager>(userStore.Object);
var owin = new OwinContext();
owin.Set(appUserMgrMock.Object);
HttpContext.Current = new HttpContext(new HttpRequest(null, "http://test.com", null), new HttpResponse(null));
HttpContext.Current.Items["owin.Environment"] = owin.Environment;
var userStore=new Mock();
var appUserMgrMock=new Mock(userStore.Object);
var owin=new OwinContext();
Set(appUserMgrMock.Object);
当前=新的HttpContext(新的HttpRequest(null)http://test.com“,null),新的HttpResponse(null));
HttpContext.Current.Items[“owin.Environment”]=owin.Environment;
请记住安装所有必需的nuget软件包 为文字墙道歉-我想提供尽可能多的上下文:遗憾的是,没有一个答案是真正的答案,而不是解决办法。我不想嘲笑它,我想实际测试它。哦,好吧。你觉得用户经理怎么样?在本单元的上下文中,您是如何发现这一点的
var controller = new MyController();
controller.Request = new HttpRequestMessage(HttpMethod.Post,
new Uri("api/data/validate", UriKind.Relative)
);
controller.Request.SetOwinContext(new OwinContext());
private static IDictionary<string, object> GetOwinEnvironment(this HttpContextBase context)
{
return (IDictionary<string, object>) context.Items[HttpContextItemKeys.OwinEnvironmentKey];
}
var request = new HttpRequest("", "http://google.com", "rUrl=http://www.google.com")
{
ContentEncoding = Encoding.UTF8 //UrlDecode needs this to be set
};
var ctx = new HttpContext(request, new HttpResponse(new StringWriter()));
//Session need to be set
var sessionContainer = new HttpSessionStateContainer("id", new SessionStateItemCollection(),
new HttpStaticObjectsCollection(), 10, true,

//this adds aspnet session
ctx.Items["AspSession"] = typeof(HttpSessionState).GetConstructor(
BindingFlags.NonPublic | BindingFlags.Instance,
null, CallingConventions.Standard,
new[] { typeof(HttpSessionStateContainer) },
null)
.Invoke(new object[] { sessionContainer });
var data = new Dictionary<string, object>()
{
{"a", "b"} // fake whatever you need here.
};
ctx.Items["owin.Environment"] = data;
var data = new Dictionary<string, object>()
{

};
ctx.Items["owin.Environment"] = data;
var userStore = new Mock<IUserStore<User>>();
var appUserMgrMock = new Mock<ApplicationUserManager>(userStore.Object);
var owin = new OwinContext();
owin.Set(appUserMgrMock.Object);
HttpContext.Current = new HttpContext(new HttpRequest(null, "http://test.com", null), new HttpResponse(null));
HttpContext.Current.Items["owin.Environment"] = owin.Environment;
