问题描述
我在项目中使用新的Web API位，并且发现我无法使用普通的HttpMessageRequest，因为我需要向请求中添加客户端证书.结果，我正在使用HttpClient(所以我可以使用WebRequestHandler).这一切都很好，除非它对存根/模拟不友好，至少对于Rhino Mocks而言.
I am using the new Web API bits in a project, and I have found that I cannot use the normal HttpMessageRequest, as I need to add client certificates to the request. As a result, I am using the HttpClient (so I can use WebRequestHandler). This all works well, except that it isn't stub/mock friendly, at least for Rhino Mocks.
我通常会在HttpClient周围创建一个包装服务，但我想尽可能避免这种情况，因为有很多方法需要包装.我希望我缺少有关如何存根HttpClient的任何建议?
I would normally create a wrapper service around HttpClient that I would use instead, but I would like to avoid this if possible, as there are a lot of methods that I would need to wrap. I am hoping that I have missing something—any suggestions on how to stub HttpClient?
推荐答案
我使用Moq，可以存根HttpClient.我认为Rhino Mock也是一样(我自己没有尝试过).如果只想对HttpClient存根，则下面的代码应该可以工作:
I use Moq and I can stub out the HttpClient. I think this the same for Rhino Mock (I haven’t tried by myself).If you just want to stub the HttpClient the below code should work:
var stubHttpClient = new Mock<HttpClient>();
ValuesController controller = new ValuesController(stubHttpClient.Object);
如果我错了，请纠正我.我猜您在这里指的是在HttpClient中存根成员.
Please correct me if I’m wrong. I guess you are referring to here is that stubbing out members within HttpClient.
大多数流行的隔离/模拟对象框架不允许您对非虚拟成员进行存根/设置例如，下面的代码引发异常
Most popular isolation/mock object frameworks won’t allow you to stub/setup on non- virtual membersFor example the below code throws an exception
stubHttpClient.Setup(x => x.BaseAddress).Returns(new Uri("some_uri");
您还提到要避免创建包装器，因为您将包装许多HttpClient成员.不清楚为什么需要包装许多方法，但是您可以轻松地仅包装所需的方法.
You also mentioned that you would like to avoid creating a wrapper because you would wrap lot of HttpClient members. Not clear why you need to wrap lots of methods but you can easily wrap only the methods you need.
例如:
public interface IHttpClientWrapper { Uri BaseAddress { get; } }
public class HttpClientWrapper : IHttpClientWrapper
{
readonly HttpClient client;
public HttpClientWrapper() {
client = new HttpClient();
}
public Uri BaseAddress {
get
{
return client.BaseAddress;
}
}
}
