在 route 文件里有个 beego.AutoPrefix()函数,然后

func (p *ControllerRegister) AddAutoPrefix(prefix string, c ControllerInterface) {
reflectVal := reflect.ValueOf(c)
rt := reflectVal.Type()
ct := reflect.Indirect(reflectVal).Type()
controllerName := strings.TrimSuffix(ct.Name(), "Controller")
for i := 0; i < rt.NumMethod(); i++ {
if !utils.InSlice(rt.Method(i).Name, exceptMethod) {
route := &ControllerInfo{}
route.routerType = routerTypeBeego
route.methods = map[string]string{"*": rt.Method(i).Name}
route.controllerType = ct
pattern := path.Join(prefix, strings.ToLower(controllerName), strings.ToLower(rt.Method(i).Name), "*")
patternInit := path.Join(prefix, controllerName, rt.Method(i).Name, "*")
patternFix := path.Join(prefix, strings.ToLower(controllerName), strings.ToLower(rt.Method(i).Name))
patternFixInit := path.Join(prefix, controllerName, rt.Method(i).Name)
route.pattern = pattern
for m := range HTTPMETHOD {
p.addToRouter(m, pattern, route)
p.addToRouter(m, patternInit, route)
p.addToRouter(m, patternFix, route)
p.addToRouter(m, patternFixInit, route)
}
}
}
}

patternFix := path.Join(prefix, strings.ToLower(controllerName), strings.ToLower(rt.Method(i).Name))
这句话
