我正在使用Microsoft.Owin.Testing
库集成测试内存中的API。我已经在OWIN JWT中间件中添加了我的身份验证需求,现在我正在尝试传递生成的令牌来测试需要授权的控制器的请求。我可以向您保证JWT中间件设置正确,因为它在正常使用时工作得很好。但是,我观察到TestServer.HttpClient
对象的一些奇怪行为。当我在HttpClient上设置默认授权头以传递令牌时,我的测试永远不会通过,因为无法识别令牌。但是,当我使用TestServer.CreateRequest(...)
时,测试会正确传递并识别令牌。我更喜欢使用HttpClient方法,因为它们使用PostAsJsonAsync
等所提供的所有扩展方法使事情变得更加容易。我开始认为{{1}中有一个错误或者我完全错过了什么。
这是我的测试类(使用NUnit3):
TestServer.HttpClient
我的控制员:
public class DefinitionsControllerTests
{
private TestServer _server;
private string _accessToken;
[SetUp]
public void Setup()
{
_server = TestServer.Create<Startup>();
var credentials = new FormUrlEncodedContent(new[] {
new KeyValuePair<string, string>("grant_type", "password"),
new KeyValuePair<string, string>("username", "john.doe@mail.com"),
new KeyValuePair<string, string>("password", "testing123")
});
// get token from OWIN JWT middleware
dynamic resultBody = JObject.Parse(
_server.HttpClient.PostAsync("/oauth/token", credentials).Result.Content.ReadAsStringAsync().Result);
_accessToken = (string)resultBody.access_token;
// this does not appear to ever work
_server.HttpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", _accessToken);
}
[TearDown]
public void TearDown()
{
_server.Dispose();
}
[Test]
public void GetById_WithExistingId()
{
// 401 Unauthorized response everytime and test fails
var response = _server.HttpClient.GetAsync($"/api/definitions/{expected.Id}").Result;
var actual = response.Content.ReadAsAsync<Definition>().Result;
// 200 Ok every time and test passes
// - these variables aren't part of the test but rather to show alternate request creation method that works
var response2 = _server.CreateRequest($"/api/definitions/{expected.Id}")
.AddHeader("Authorization", "Bearer " + _accessToken)
.GetAsync()
.Result;
var actual2 = response.Content.ReadAsAsync<Definition>().Result;
response.StatusCode.ShouldBe(HttpStatusCode.OK);
actual.ShouldNotBeNull();
}
//...other test methods
}
任何人都知道为什么只有CreateRequest()有效?这有点令人生气。

问题是HttpClient属性每次都返回一个新实例。如果您保存该实例并重新使用它,它将起作用。 https://github.com/aspnet/AspNetKatana/blob/b850cd8b4de61e65bbd7127ce02b5df7c4cb6db5/src/Microsoft.Owin.Testing/TestServer.cs#L48
