我有一个控制器，我在一个Restful API中使用作为.NET Core 2 MVC应用程序的一部分。下面我粘贴了控制器的代码。核心2控制器 - HTTP动词不允许
除了最后一种方法之外，一切都很好。 [HttpDelete("Race/{raceid}")]。当我尝试从Postman或Swagger发出DELETE时，我得到“用于访问此页面的HTTP动词是不允许的”
我不明白为什么。我的标准删除方法工作正常。这只是第二个删除方法。我有GET方法遵循类似的模式，他们工作正常。
任何想法？

请求的外观如何？ 'DELETE/api/Timing/Race/1234'？ –
是的，这是正确的。这里是一个示例卷曲curl -X DELETE - 标头授权：承载' - 标头'接受：text/html''https://www.techsportise.com/api/Timing/Race/1'--header'接受：text/html''https://www.techsportise.com/api/Timing/Race/1' –
尝试将'Race/{raceid}'删除放在{id}删除之上。首先有特殊的端点总是更好。我最好的猜测是'Race/1'与{id}匹配，然后不能绑定。我总是喜欢在我的端点上使用{id：int}，只要我知道它总是一个整数。 – NathanS
