删除返回错误405（方法不允许）我正在使用React和ASP.Net Core

Question

我正在尝试使用行上的 id 来删除该行。当我在本地服务器上执行它时，它工作正常，但在 plesk 服务器上有错误。 请求 CREATE 和 GET 工作正常，但 DELETE 和 UPDATE 不起作用。

功能删除：

onDeleteConfirmation(e) {
    e.preventDefault();
    const { id } = this.props.match.params;

    axios.delete("api/Trips/DeleteTrip/" + id).then(result => {
        this.props.history.push('/Trips')
    });
}

功能更新：

onUpdateConfirmation(e) {
    e.preventDefault();
    const { id } = this.props.match.params;
    let tripObject = {
        name: this.state.name,
        description: this.state.description,
        dateStarted: this.state.dateStarted,
        dateComplated: this.state.dateComplated
    }
    axios.put("api/Trips/UpdateTrip/"+id, tripObject).then(result => {
        this.props.history.push('/Trips')
    });
}

控制器服务：

[HttpDelete("DeleteTrip/{id}")]
    public IActionResult DeleteTrip(int id)
    {
        _service.DeleteTrip(id);
        return Ok();
    }

。 我在 Visual Stdio 中使用 ASP.Net Core 3 和 React。 当我尝试在在线服务器 Plesk 上执行时，我的问题就解决了。

这是完整的控制器：

    [ApiController]
    public class TripsController : ControllerBase
    {
        public ITripService _service { get; set; }

        public TripsController(ITripService service)
        {
            _service = service;
        }

        [EnableCors("AnotherPolicy")]
        [HttpGet("GetTrips")]
        public IActionResult GetTrips()
        {
            try
            {
                //throw new Exception();
                var allTrips = _service.GetAllTrips();
                return Ok(allTrips);
            }
            catch (Exception ex)
            {
                return BadRequest(ex.Message);
            }

        }

        [EnableCors("AnotherPolicy")]
        [HttpGet("SingleTrip/{id}")]
        public IActionResult GetTripById(int id)
        {
            var trip = _service.GetTripById(id);
            return Ok(trip);
        }

        [EnableCors("AnotherPolicy")]
        [HttpPost("AddTrip")]
        public IActionResult AddTrip([FromBody] Trip trip)
        {
            if (trip != null)
            {
                _service.AddTrip(trip);
            }
            return Ok();
        }

        [EnableCors("AnotherPolicy")]
        [HttpPut("UpdateTrip/{id}")]
        public IActionResult UpdateTrip(int id, [FromBody] Trip trip)
        {
            _service.UpdateTrip(id, trip);
            return Ok(trip);
        }

        [EnableCors("AnotherPolicy")]
        [HttpDelete("DeleteTrip/{id}")]
        public IActionResult DeleteTrip(int id)
        {
            _service.DeleteTrip(id);
            return Ok();
        }

    }
}

根据 Plesk 的说法，这是因为 WebDAV 和 .NET Core IIS 处理程序冲突，建议从网站配置中禁用 WebDAV 模块及其标头。

https://support.plesk.com/hc/en-us/articles/360008566053-HTTP-Error-405-Method-Not-Allowed-when-using-PUT-method-in-ASP-NET-or- NET-Core-应用程序与 Web-API

将以下代码添加到您的 web.config 文件中。

<system.webServer>
   <modules>
      <!-- Remove WebDAV module so that we can make DELETE requests -->
      <remove name="WebDAVModule" />
   </modules>

   <handlers>
      <!-- Remove WebDAV module so that we can make DELETE requests -->
      <remove name="WebDAV" />

      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
   </handlers>
    
   other configs here...
    
</system.webServer>

每次将应用程序文件上传到 Plesk 面板之前，您可能都必须执行此操作。

为了防止在发布应用程序时执行此操作，请将更新的 web.config 包含在项目的根目录中。一旦您构建，它将包含在您的构建中。

干杯！

您需要在响应中添加 CORS 标头以启用跨源 DELETE 请求。

https://learn.microsoft.com/en-us/aspnet/core/security/cors?view=aspnetcore-5.0

在你的

Startup.cs

：

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(options => { // <--- define a policy
        options.AddDefaultPolicy(builder => {
            builder.WithOrigins(
                "http://example.com",
                "http://www.contoso.com"
            )
            .AllowAnyHeader()
            .AllowAnyMethod();
        });
    });
    // ...
}


public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // ...
    app.UseRouting();

    app.UseCors(); // <--- enable the middleware

    // ...
    app.UseEndpoints(endpoints => { endpoints.MapControllers(); });
}

进行此更改后，响应应包含

Access-Control-Allow-...

 标头。
