創(chuàng)新互聯(lián)IRIS教程：iris中間件
使用空白中間件替換默認中間件
app := iris.New()替換為
目前成都創(chuàng)新互聯(lián)已為上千余家的企業(yè)提供了網(wǎng)站建設、域名、網(wǎng)頁空間、網(wǎng)站托管、服務器租用、企業(yè)網(wǎng)站設計、虎丘網(wǎng)站維護等服務，公司將堅持客戶導向、應用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長，共同發(fā)展。
app := iris.Default()使用中間件
package main
import (
"github.com/kataras/iris/v12"
"github.com/kataras/iris/v12/middleware/recover"
)
func main() {
// Creates an iris application without any middleware by default
app := iris.New()
// Global middleware using `UseRouter`.
//
// Recovery middleware recovers from any panics and writes a 500 if there was one.
app.UseRouter(recover.New())
// Per route middleware, you can add as many as you desire.
app.Get("/benchmark", MyBenchLogger(), benchEndpoint)
// Authorization group
// authorized := app.Party("/", AuthRequired())
// exactly the same as:
authorized := app.Party("/")
// per group middleware! in this case we use the custom created
// AuthRequired() middleware just in the "authorized" group.
authorized.Use(AuthRequired())
{
authorized.Post("/login", loginEndpoint)
authorized.Post("/submit", submitEndpoint)
authorized.Post("/read", readEndpoint)
// nested group
testing := authorized.Party("testing")
testing.Get("/analytics", analyticsEndpoint)
}
// Listen and serve on 0.0.0.0:8080
app.Listen(":8080")
}
中間件中的GOroutine
在中間件或處理程序中啟動新的 Goroutines 時，您不應該使用其中的原始上下文，您必須使用只讀副本。
func main() {
app := iris.Default()
app.Get("/long_async", func(ctx iris.Context) {
// create a clone to be used inside the goroutine
ctxCopy := ctx.Clone()
go func() {
// simulate a long task with time.Sleep(). 5 seconds
time.Sleep(5 * time.Second)
// note that you are using the copied context "ctxCopy", IMPORTANT
log.Printf("Done! in path: %s", ctxCopy.Path())
}()
})
app.Get("/long_sync", func(ctx iris.Context) {
// simulate a long task with time.Sleep(). 5 seconds
time.Sleep(5 * time.Second)
// since we are NOT using a goroutine, we do not have to copy the context
log.Printf("Done! in path: %s", ctx.Path())
})
app.Listen(":8080")
}
