asp.net-mvc – 为什么这两个API方法会产生冲突

API控制器有两种方法：

[AllowAnonymous]
    [AcceptVerbs("Post","Get")]
    public ArtifactContent Post(string userName,string password,string id) ...

和

[AllowAnonymous]
    [AcceptVerbs("Get")]
    public HttpResponseMessage Get(string userName,string id,EnumType contentType) ...

虽然这两种方法显然有不同的方法签名,但我们收到以下错误消息：

{“Message”:”An error has occurred.”,”ExceptionMessage”:”Multiple
actions were found that match the request:
[XXX].Models.ArtifactContent Post(System.String,System.String,
System.String) on type
[XXX].API.ArtifactContentControllerrnSystem.Net.Http.HttpResponseMessage
Get(System.String,ArtifactContentTypes) on type
[XXX].API.ArtifactContentController”,”ExceptionType”:”System.InvalidOperationException”,”StackTrace”:”

System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsyncInternal(HttpRequestMessage
request,CancellationToken cancellationToken)rn at
System.Web.Http.Dispatcher.HttpControllerDispatcher.SendAsync(HttpRequestMessage
request,CancellationToken cancellationToken)”}

我们可以通过进行这两个更改中的一个来解决错误,但我真的想知道为什么.NET在两个签名明显不同时抛出错误：

>从Post方法中删除Get AcceptVerbs属性
>更改Get方法的签名以将Enum接受为整数
