Question

我在主题中得到了Exception：

System.ArgumentException ：执行此操作需要HttpContext 操作。检查Web中是否正在执行此操作请求。

每次我都试图测试一种方法。我创建了一个HttpContext：

[TestInitialize]
public void Initialize()
{
    #region declarations
    Mock<IUnitOfWork> mock = new Mock<IUnitOfWork>();
    Mock<IAntiForgeryValidator> antiForgeryMock = new Mock<IAntiForgeryValidator>();
    var context = new Mock<HttpContextBase>();
    #endregion

    #region repository mock setups
    mock.Setup(m => m.deviceRepository.Get(
        It.IsAny<List<Expression<Func<Device, bool>>>>(),
        It.IsAny<Func<IQueryable<Device>, IOrderedQueryable<Device>>>(),
        null))
        .Returns(new[] { new Device { Id = 1, Manufacturer = "a", Name = "b", CatalogNo = "x" } });
    mock.Setup(m => m.deviceRepository.Get()).Returns(new[] { new Device { Id = 1, Manufacturer = "a", Name = "b", CatalogNo = "z" } });
    mock.Setup(m => m.deviceRepository.GetByID(It.IsAny<int>())).Returns(new Device { Id = 1, Manufacturer = "a", Name = "b", CatalogNo = "15" });
    mock.Setup(m => m.deviceRepository.GetByID(It.IsInRange(-1, 1, Range.Exclusive))).Returns(default(Device));
    #endregion

    #region Mocking Request in purpose of testing Post Methods 
    Mock<HttpRequestBase> Request = new Mock<HttpRequestBase>();
    WebHeaderCollection Headers = new WebHeaderCollection();
    Headers.Add("Connection", "keep-alive");
    Headers.Add("Content-Length", "82");
    Headers.Add("RequestVerificationToken", "AAAAAAAAAAAAAAAAAAAAAAA:BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB");
    Request.SetupGet(x => x.Headers).Returns(Headers);
    context.SetupGet(x => x.Request).Returns(Request.Object);
    #endregion

    #region Mocking Validation 
     antiForgeryMock.Setup(m => m.Validate(
        It.IsAny<string>(),
        It.IsAny<string>()))
        .Callback((string cookieToken, string formToken) =>
        {
            // call back
        });
    #endregion

    DC = new DeviceController(fakeRepo);
    DC.ControllerContext = new ControllerContext(context.Object,new RouteData(),DC);
}

但是在尝试执行以下代码时：

[TestMethod]
public void EditPost()
{
    var data = default(Device);
    var result = DC.Edit(data);
    Assert.IsNotNull(result);
}

我不知道为什么我得到一个例外，告诉我没有HttpContext。我创建它并将其绑定到控制器对象。

我正在测试代码：

 [HttpPost]
    //[ValidateAntiForgeryToken]
    public ActionResult Edit([Bind(Include="Id,Name,Manufacturer,CatalogNo")] Device device)
    {
        ValidateRequestHeader(Request);
        if (String.IsNullOrWhiteSpace(device.Name) || String.IsNullOrWhiteSpace(device.Manufacturer) || String.IsNullOrWhiteSpace(device.CatalogNo))
        {
            ModelState.AddModelError("", "Niepoprawne dane");
            return PartialView(device);
        }
        unitOfWork.deviceRepository.Update(device);
        unitOfWork.Save();
        return Json(new { ok = true, newurl = Url.Action("Index") });
    }
AntiForgeryValidator a = new AntiForgeryValidator();

public void ValidateRequestHeader(HttpRequestBase request) 
{
    string cookieToken = "";
    string formToken = "";

    if (request.Headers["RequestVerificationToken"] != null)
    {
        string[] tokens = request.Headers["RequestVerificationToken"].Split(':');
        if (tokens.Length == 2)
        {
            cookieToken = tokens[0].Trim();
            formToken = tokens[1].Trim();
        }
    }
    a.Validate(cookieToken, formToken);
    //AntiForgery.Validate(cookieToken, formToken);
}
public interface IAntiForgeryValidator
{
    //void ValidateRequestHeader(HttpRequestBase request);
    void Validate(string cookieToken, string formToken);
}
public class AntiForgeryValidator : IAntiForgeryValidator
{
    public void Validate(string cookieToken, string formToken)
    {
        AntiForgery.Validate(cookieToken, formToken);
    }
}

@Update StackTrace指向此方法导致异常：AntiForgery.Validate(cookieToken, formToken);

就像你在unitOfWork中嘲笑Edit()变量一样，设置IAntiForgeryValidator。现在你明确地创建了一个真实的＆＃34; AntiForgeryValidator在Edit()之外使用该构造函数调用。只需将a切换为与unitOfWork相同的变量（假设您以某种方式注入unitOfWork），并a为IAntiForgeryValidator，不是明确AntiForgeryValidator，然后它应该工作。我假设您对unitOfWork的模拟调用工作正常，我无法在您显示控制器中声明/实例化unitOfWork变量的情况下提供更多详细信息。
