Why GetBy can't be accessed, but PostBy can

Hello everyone, we are currently experiencing a strange problem and would like to ask for your help, as follows.

GET, visit http://127.0.0.1:8080/project/1, return 404

POST, visit http://127.0.0.1:8080/project/1, return 200

Only GetBy(id int64) is defined in the controller, not PostBy.

The code is as follows.

iris version:V12

controller:

```
// http://127.0.0.1:8080/project/1
func (p *ProjectController) GetBy(id int64) *proto.RspProject {
p.Ctx.Application().Logger().Infof(`get project info`) //should be prinf
ret := proto.NewRspProject()
return ret
}
```

route defined：

```
//route interface
type router interface {
setup(*mvc.Application)
path() string
}

//router manager:
func (r *routerMgr) Init(app *iris.Application) {
for _, v := range r.routers {
mvc.Configure(app.Party(v.path(), crs).AllowMethods(iris.MethodGet, iris.MethodPost), v.setup)
}
}

func (r *routerMgr) register(route ...router) {
r.routers = append(r.routers, route...)
}
//
//
//
//route define：
type projectRoute int

func (r *projectRoute) path() string {
return `/project`
}

func (r *projectRoute) setup(app *mvc.Application) {
servPro := services.NewProjectService()
sessManager := sessions.New(sessions.Config{
Cookie: "project",
Expires: 60 * time.Minute,
AllowReclaim: true,
})
app.Register(servPro, sessManager.Start)
app.Handle(new(controllers.ProjectController))
}
//
//
//
//somewhere register
NewRouterMgr().register(
new(usersRoute),
new(projectRoute),
)
```
