[InlineData(HttpStatusCode.OK)]
[InlineData(HttpStatusCode.BadRequest)]
[InlineData(HttpStatusCode.Unauthorized)]
[InlineData(HttpStatusCode.Forbidden)]
[InlineData(HttpStatusCode.NotFound)]
[InlineData(HttpStatusCode.InternalServerError)]
public async Task HttpStatusTest(HttpStatusCode httpStatusCode)
{var httpHandler new MockHttpHandler(req new HttpResponseMessage(httpStatusCode));using var httpClient new HttpClient(httpHandler);using var response await httpClient.GetAsync(http://localhost:32123/api/values);Assert.Equal(httpStatusCode, response.StatusCode);
}如果有需要在测试的过程中修改模拟的行为可以通过 SetResponseFactory 方法来[Fact]
public async Task SetResponseFactoryTest()
{var httpHandler new MockHttpHandler();using var httpClient new HttpClient(httpHandler);var response await httpClient.GetAsync(http://localhost:32123/api/values);Assert.Equal(HttpStatusCode.OK, response.StatusCode);httpHandler.SetResponseFactory(req new HttpResponseMessage(HttpStatusCode.BadRequest));response await httpClient.GetAsync(http://localhost:32123/api/values);Assert.Equal(HttpStatusCode.BadRequest, response.StatusCode);
}上面的方式都是直接指定了 response我们也可以根据请求信息动态地返回 response[Fact]
public async Task DynamicResponseTest()
{var httpHandler new MockHttpHandler(req new HttpResponseMessage(HttpStatusCode.OK){Content new StringContent(req.Method.Method)});using var httpClient new HttpClient(httpHandler);var response await httpClient.GetStringAsync(http://localhost:32123/api/values);Assert.Equal(HttpMethod.Get.Method, response);using var httpResponse await httpClient.PostAsync(http://localhost:32123/api/values, new StringContent());response await httpResponse.Content.ReadAsStringAsync();Assert.Equal(HttpMethod.Post.Method, response);
}Implement实现代码很简单大致如下根据自定义的逻辑去返回 response 即可public sealed class MockHttpHandler : HttpMessageHandler
{private FuncHttpRequestMessage, TaskHttpResponseMessage _responseFactory;public MockHttpHandler() : this(_ Task.FromResult(new HttpResponseMessage(HttpStatusCode.OK))){}public MockHttpHandler(FuncHttpRequestMessage, HttpResponseMessage responseFactory){Guard.NotNull(responseFactory);_responseFactory req Task.FromResult(responseFactory(req));}public MockHttpHandler(FuncHttpRequestMessage, TaskHttpResponseMessage responseFactory){Guard.NotNull(responseFactory);_responseFactory responseFactory;}public void SetResponseFactory(FuncHttpRequestMessage, HttpResponseMessage responseFactory){Guard.NotNull(responseFactory);_responseFactory req Task.FromResult(responseFactory(req));}public void SetResponseFactory(FuncHttpRequestMessage, TaskHttpResponseMessage responseFactory){Guard.NotNull(responseFactory);_responseFactory responseFactory;}protected override TaskHttpResponseMessage SendAsync(HttpRequestMessage request, CancellationToken cancellationToken){return _responseFactory(request);}
}More在需要模拟 Http API 的响应时可以考虑使用这种方式希望对你有帮助最近有几位小伙伴希望建一个微信交流群于是建了一个微信群有需要的小伙伴可以扫描下面的二维码加群如果二维码失效也可以加我微信来加群Referenceshttps://github.com/WeihanLi/WeihanLi.Common/blob/dev/src/WeihanLi.Common/Http/MockHttpHandler.cshttps://github.com/WeihanLi/WeihanLi.Common/blob/dev/test/WeihanLi.Common.Test/HttpTest/MockHttpHandlerTest.cs
