AspNet 核心集成测试 - MethodNotAllowed 响应

Question

我创建了一个带有 GET、POST、PUT 路由的 webapi 项目，这些路由在邮递员中运行良好。但是当我进行集成测试时，只有 GET 和 POST 路由通过。在集成测试中发出 PUT 请求时，它会抛出 MethodNotAllowed Error (405 - Method not allowed)。

系统：Ubuntu 18.10 dotnet 版本：2.2.100

任何建议/方向将不胜感激。

namespace TestingMvc.Tests {

public class JsonContent : StringContent {

    public JsonContent (object obj):

        base (JsonConvert.SerializeObject (obj), Encoding.UTF8, "application/json") { }

}

public class MyTest : IClassFixture<WebApplicationFactory<WebApi.Startup>> {

    private readonly WebApplicationFactory<WebApi.Startup> _factory;

    public MyTest (WebApplicationFactory<WebApi.Startup> factory) {

        _factory = factory;

    }

    // This is Ok -> Returns 200

    [Fact]

    public async Task Get_Attachments () {

        var client = _factory.CreateClient ();

        var response = await client.GetAsync ("/attachments");

        Assert.Equal (HttpStatusCode.OK, response.StatusCode);

    }

    // This is Ok -> returns 200

    [Fact]

    public async Task Post_Attachments () {

        var client = _factory.CreateClient ();

        var response = await client.PostAsync ("/attachments", new JsonContent(new { a = "foobaz" }));

        Assert.Equal (HttpStatusCode.OK, response.StatusCode);

    }

    // This is not ok -> returns 405 Method not allowed

    [Fact]

    public async Task Put_Attachments () {

        var client = _factory.CreateClient ();

        var response = await client.PutAsync ("/attachments", new JsonContent(new { a = "foobaz" }));

        Assert.Equal (HttpStatusCode.OK, response.StatusCode);

    }

}

}

Answer 1

我忘了发布我的控制器。&nbsp; &nbsp; // PUT Attachments/someguid&nbsp; &nbsp; [HttpPut ("{id}")]&nbsp; &nbsp; public ActionResult<AttachmentDto> Put (Guid id, [FromBody] AttachmentDto attachment) {&nbsp; &nbsp; &nbsp; &nbsp; return Ok (_attachmentService.CreateOrUpdate (id, attachment));&nbsp; &nbsp; }因此，为该操作定义了一个 ID 参数，但在集成测试中它丢失了。它应该是：var response = await client.PutAsync ("/attachments/01D7ACA3-575C-4E60-859F-DB95B70F8190", ...这解决了我的问题。

您是否将 Postman 通过的 Header 与您的测试构建的 Header 进行了比较？我可以看到的一件事可能是问题是您没有发送内容类型。ContentType = "文本/json"
