如何Mock一个HttpClient

MockHttpClient.cs

var httpClientMock = new Mock<HttpClient>();
// Set up the SendAsync method to return a desired response
httpClientMock
    .Setup(x => x.SendAsync(It.IsAny<HttpRequestMessage>(), CancellationToken.None))
    .ReturnsAsync(new HttpResponseMessage(HttpStatusCode.OK));
            
// Set up the SendAsync method to match a specific URL and return a desired response
httpClientMock
    .Setup(x => x.SendAsync(It.Is<HttpRequestMessage>(req => req.RequestUri.AbsoluteUri == "https://example.com/api/data"), CancellationToken.None))
    .ReturnsAsync(new HttpResponseMessage(HttpStatusCode.OK) { Content = new StringContent("Mocked response") });
