7.6. 全局请求中间件
package main
/*
AddMiddleware 方法如果第一个参数为字符串"global",则作为全局请求中间件添加给App(使用DefaultHandlerExtend创建请求处理函数),否则等同于调用app.Rputer.AddMiddleware方法。
func (app *App) AddMiddleware(hs ...interface{}) error {
if len(hs) > 1 {
name, ok := hs[0].(string)
if ok && name == "global" {
handler := DefaultHandlerExtend.NewHandlerFuncs("", hs[1:])
app.Info("Register app global middleware:", handler)
app.HandlerFuncs = HandlerFuncsCombine(app.HandlerFuncs[0:len(app.HandlerFuncs)-1], handler)
app.HandlerFuncs = HandlerFuncsCombine(app.HandlerFuncs, HandlerFuncs{app.serveContext})
return nil
}
}
return app.Router.AddMiddleware(hs...)
}
