Question

在我的web api应用程序中，我想让客户端使用相同的路径发出请求，但是传递不同类型的参数。

例如：

container.Register<HttpContextBase>(() =>
    new HttpContextWrapper(HttpContext.Current), 
    Lifestyle.Scoped);

container.Register<DataSource>(() =>
    {
        var httpContext = container.GetInstance<HttpContextBase>();
        return MasterDataSource.WithUser(httpContext?.User?.Identity?.Name);
    }, 
    Lifestyle.Scoped);

我希望每个方法的网址都相似，例如：

public class MyController : ApiController
{
   [HttpDelete]
   public IHttpActionResult Delete(int id) {..}

   [HttpDelete]
   public IHttpActionResult Delete2(Guid id) {..}

   [HttpDelete]
   public IHttpActionResult Delete3(string id) {..}

}

这可能吗？我尝试了很多具有api/MyController/1 api/MyController/abc etc..属性和路由配置的组合，但似乎没有任何效果。

谢谢

您可以使用attribute routing。例如：

[RoutePrefix("MyController")]
public class MyController : ApiController
{
   [HttpDelete]
   [Route("delete/{id:int}")]
   public IHttpActionResult Delete(int id) {..}

   [HttpDelete]
   [Route("delete/{id:guid}")]
   public IHttpActionResult Delete2(Guid id) {..}

   [HttpDelete]
   [Route("delete/{id:alpha}")]
   public IHttpActionResult       Delete3(string id) {..}

}

如果您这样做，那么请求网址将是：

http://yoursever/mycontroller/delete/123
http://yoursever/mycontroller/delete/abc
http://yoursever/mycontroller/delete/91c74f8f-d981-4ee1-ba36-3e9416bba202

您需要为每个方法提供具有不同参数类型的Route：

[RoutePrefix("api/MyController")]
public class MyController : ApiController
{
   [HttpDelete]
   [Route("{id:int}", Order = 1)]
   public IHttpActionResult Delete(int id) {..}

   [HttpDelete]
   [Route("{id:guid}", Order = 2)]
   public IHttpActionResult Delete2(Guid id) {..}

   [HttpDelete]
   [Route("{id}", Order = 3)]
   public IHttpActionResult Delete3(string id) {..}

}

当然，如果你还没有，你必须enable attribute routing Order属性的Route属性可确保以正确的顺序检查路由模板，以使int值与字符串路由不匹配。

是的，这是可能的。尝试将路线设为decoration。

示例：

        [Route("DeleteThis/{id}")]
        [HttpDelete]
        public IHttpActionResult DeleteThis(int id)
        {
            return Ok();
        }

        [Route("NowDeleteThis/{name}")]
        [HttpDelete]
        public IHttpActionResult DeleteThis(string name)
        {
            return Ok();
        }

用于重载控制器方法的相同URL
