ActionFilter只应用于MVC模式,使用UseMvc开启Mvc中间件;在ControllerBuilder中创建Filter. 支持正则表达式与统配符*.
func CreateCustomBuilder() *abstractions.HostBuilder {
return yoyogo.NewWebHostBuilder().
UseFastHttp().
Configure(func(app *yoyogo.WebApplicationBuilder) {
app.UseMvc(func(builder *mvc.ControllerBuilder) {
builder.AddController(contollers.NewUserController)
builder.AddFilter("/v1/user/info", &contollers.TestActionFilter{})
})
})
}
它实现了IActionFilter接口,如下是它的实例定义.
type TestActionFilter struct {
}
func (f *TestActionFilter) OnActionExecuting(context mvc.ActionFilterContext) bool {
fmt.Println("TestActionFilter OnActionExecuting")
return false
}
func (f *TestActionFilter) OnActionExecuted(context mvc.ActionFilterContext) {
fmt.Println("TestActionFilter OnActionExecuted")
}
