我要做的

使用PATCH动词

在我的Web API中针对控制器方法运行集成测试

mycontroller.cs

namespace FluidIT.API.Controllers
{
    [Route("api/v1/[controller]")]
    [ApiController]
    public class MyController : ControllerBase
    {
        private readonly IMediator _mediator;
        private readonly IMyQueries _myQueries;
        public JobsController(IMediator mediator, IMyQueries myQueries)
        {
            _mediator = mediator ?? throw new ArgumentNullException(nameof(mediator));
            _myQueries = myQueries ?? throw new ArgumentNullException(nameof(myQueries));
        }
        // PATCH: api/v1/my/{id}
        [Route("id:int")]
        [HttpPatch]
        public async Task<IActionResult> RemoveMeAsync(int id)
        {
            bool commandResult = false;
            try
            {
                commandResult = await _mediator.Send(new RemoveMeCommand(id));
                return NoContent();
            }
            catch (NotFoundException)
            {
                return NotFound(id);
            }
        }
    }
}

myIntegrationTest.cs

[Fact]
async Task Patch_MyAsync_WhenIdNotFound_ReturnsNotFoundStatusCode()
{
    // Arrange
    var request = new HttpRequestMessage()
    {
        RequestUri = new Uri($"{_fixture.Client.BaseAddress}{_baseRoute}/1"),
        Method = HttpMethod.Patch,
        Headers =
        {
            { HttpRequestHeader.ContentEncoding.ToString(), Encoding.UTF8.ToString() },
            { HttpRequestHeader.ContentType.ToString(), "application/json" }
        }
    };
    // Act
    var response = await _fixture.Client.SendAsync(request);
    // Assert
    Assert.Equal(HttpStatusCode.NotFound, response.StatusCode);
}

我到目前为止所做的

我已经看到，当尝试使用PUT，PATCH或DELETE HTTP动词时，这是一个相当普遍的事件。我还看到，将以下内容添加到web.config文件中以从IIS中删除webDAV模块是建议的解决方案

博客文章

web.config

<?xml version="1.0" encoding="utf-8"?>
    <configuration>
      <system.webServer>
          <modules runAllManagedModulesForAllRequests="false">
            <remove name="WebDAVModule" />
          </modules>
    </system.webServer>
</configuration>

但是，正如您可能猜到的那样，此解决方案对我不起作用。我的测试返回405 MethodNotAllowed响应。

有关此主题的大多数信息似乎是从一段时间开始的，所以我想我在这里专门提出ASP.NET核心API。

要解决问题，请更正路由约束语法，将参数和datatype封闭在卷曲括号内[Route("{id:int}")]

[Route("{id:int}")]
[HttpPatch]
public async Task<IActionResult> RemoveMeAsync(int id)
{
    bool commandResult = false;
    try
    {
        commandResult = await _mediator.Send(new RemoveMeCommand(id));
        return NoContent();
    }
    catch (NotFoundException)
    {
        return NotFound(id);
    }
}
