为什么我的 POST 请求会调用我定义的 GET 函数？

Question

我正在使用 ASP.NET Web Api，并且我已经设置了一个应该同时处理 GET 和 POST 的路由。当我尝试进行 POST 调用时，它会返回此错误

Response statuscode:'405'.
Response body: {"Message":"The requested resource does not support http method 'POST'."}

所以它试图调用 GET 函数而不是我设置的 POST 函数，即使我已经单独注册了它们。

这是我的两个函数

public class EmployeeController : ApiController
{
  [System.Web.Http.HttpGet]
  public object GetApplicationFunc([FromUri]EmployeeApplicationDTO request)
  {
   //Do GET specific stuff 
  }

  [System.Web.Http.HttpPost]
  public object PostApplicationFunc([FromBody]EmployeeApplicationDTO request)
  {
   //Do totally different POST stuff
  }
}

然后这是我注册路线的方式

routes.MapHttpRoute(
name: "ApplicationGet",
routeTemplate: "application/apply",
defaults: new { controller = "Employee", action = "GetApplicationFunc"},
constraints: null);

routes.MapHttpRoute(
name: "ApplicationPost",
routeTemplate: "application/apply",
defaults: new { controller = "Employee", action = "PostApplicationFunc"},
constraints: null);

所以我指定了不同的 HTTP 路由，在同一个 'routeTemplate' 下，但只调用了“GetApplication()”，它的行为就像我的“PostApplication()”在发出 POST 请求时不存在。为什么？？？

尝试用这些替换您的路线

            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapMvcAttributeRoutes();

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

动作

public class EmployeeController : ApiController
{
   Route[("{id}"]
  public object GetApplicationFunc( int id)
  {
   //Do GET specific stuff 
  }

  public object PostApplicationFunc( EmployeeApplicationDTO request)
  {
   //Do totally different POST stuff
  }
}

假设员工Id=5 使用Get 你需要的url http//..../employee/GetApplicationFunc/5

发布 http//..../employee/PostApplicationFunc

我强烈推荐的另一种方法是使用路由属性

Route[("/Employee/GetApplication/id})"]
public object GetApplicationFunc( int id)
  {
   //Do GET specific stuff 
  }

Route[("/Employee/PostApplication")]
public object PostApplicationFunc( EmployeeApplicationDTO request)
  {
   //Do totally different POST stuff
  }
