Question

从角度前端调用删除。错误显示：

Http failure response for http://devserver.us/MyApp/api/additive/3: 404 Not Found

角客户端中的删除方法：

  onDelete(additive: Additive) {
    if (confirm("Are you sure you want to delete this additive?")) {
      var id = additive.AdditiveId;
      this._additiveService.delete(id).subscribe(result => {
        var ad = result;
        console.log(id + " has been deleted.");
        this.refresh();
      }, error => console.log(error));
    }
  }

添加服务：

  private url = this.baseUrl + "api/additive/";

  delete(id: number): Observable<Additive> {
    return this.http.delete<Additive>(this.url+id, { withCredentials: true }).catch(this.handleError);
  }

Web Api控制器：

    // DELETE api/<controller>/5
    [HttpDelete("{id}")]
    public IActionResult Delete(int id)
    {
        var deleteid = id;

        return NoContent();
    }

控制器继承自基础api控制器：

public class AdditiveController : BaseApiController
{
    ....

[Route("api/[controller]")]
public class BaseApiController : Controller
{
      ......

它在localhost中工作正常但在部署到开发服务器（IIS 10）之后，所有GET都可以工作，但是DELETE返回404 Not Found。控制器的URL是正确的。

web config允许所有动词：

<handlers>
  <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" />
</handlers>

我检查了stdout日志和事件查看器，但它们不包含任何数据。

我如何1.获取详细的错误消息或2.修复此问题？

原来问题出现在服务器上的applicationHost配置文件中。必须明确允许DELETE，但事实并非如此。

dotnet core web api DELETE在部署到IIS 8.5服务器后调用404错误
