如何在“模拟”BaseHttpContext上设置IP（UserHostAddress）？

我正在尝试创建一个虚拟的BaseHttpContext来进行一些（模拟）测试而无需执行实际请求。 我想在我的虚拟上下文中添加一个IP地址。

 string url = "http://www.google.com"; //wrap in uri Uri uri = new Uri(url); //create request var request = new HttpRequest("", uri.GetLeftPart(UriPartial.Path), uri.Query); request.ServerVariables.Add("REMOTE_ADDR", ip); //dummy context HttpContext context = new HttpContext( new HttpRequest("", uri.GetLeftPart(UriPartial.Path), uri.Query), new HttpResponse(new StringWriter(System.Text.Encoding.UTF8)) ); //wrap context var contextWrapper = new HttpContextWrapper(context); 

IP应该反映在BaseHttpContext.Request.UserHostAddress 。 像这样添加IP： request.ServerVariables.Add("REMOTE_ADDR", ip); ，导致以下exception：

不支持指定的方法。

伪装一个HttpContext看起来并不那么容易，需要做很多工作。 使用模拟框架可以使事情变得更容易。 以下是使用Moq的示例：

 /// 
 /// Fakes the HTTP context. /// 
 /// The URL. /// The ip. /// The referrer. /// A HTTP context. public static HttpContextBase FakeHttpContext(string url, string ip, string referrer) { Uri uri = new Uri(url); var context = new Mock(); var files = new Mock(); var request = new Mock(); var response = new Mock(); var session = new Mock(); var server = new Mock(); var user = new Mock(); var identity = new Mock(); request.Setup(req => req.ApplicationPath).Returns("~/"); request.Setup(req => req.AppRelativeCurrentExecutionFilePath).Returns("~/"); request.Setup(req => req.PathInfo).Returns(string.Empty); request.Setup(req => req.Form).Returns(new NameValueCollection()); request.Setup(req => req.QueryString).Returns(HttpUtility.ParseQueryString(uri.Query)); request.Setup(req => req.Files).Returns(files.Object); request.Setup(req => req.UserHostAddress).Returns(ip); request.Setup(req => req.UrlReferrer).Returns(new Uri(referrer)); request.Setup(req => req.Url).Returns(uri); request.Setup(req => req.RawUrl).Returns(url); response.Setup(res => res.ApplyAppPathModifier(It.IsAny())).Returns((string virtualPath) => virtualPath); user.Setup(usr => usr.Identity).Returns(identity.Object); identity.SetupGet(ident => ident.IsAuthenticated).Returns(true); context.Setup(ctx => ctx.Request).Returns(request.Object); context.Setup(ctx => ctx.Response).Returns(response.Object); context.Setup(ctx => ctx.Session).Returns(session.Object); context.Setup(ctx => ctx.Server).Returns(server.Object); context.Setup(ctx => ctx.User).Returns(user.Object); return context.Object; } 

灵感来自这个gitpost 。

这篇文章非常有帮助。 要解决您的问题，您只需要从post中实现HttpRequestExtensions和NameValueCollectionExtensions类。

你可以像这样使用它：

 string url = "http://127.0.0.1"; var request = new HttpRequest(string.Empty, url, string.Empty); request.AddServerVariable("REMOTE_ADDR", "127.0.0.1");
