【GoLang】golang context channel 详解

本文内容纲要：

代码示例：

packagemain import( "fmt" "time" "golang.org/x/net/context" ) funcmain(){ //ctx,cancelFunc:=context.WithDeadline(context.Background(),time.Now().Add(time.Second*5)) ctx,cancelFunc:=context.WithTimeout(context.Background(),time.Second*5) ctx=context.WithValue(ctx,"Test","123456") //defercancelFunc() ift,ok:=ctx.Deadline();ok{ fmt.Println(time.Now()) fmt.Println(t.String()) } gofunc(ctxcontext.Context){ fmt.Println(ctx.Value("Test")) for{ select{ case<-ctx.Done(): fmt.Println(ctx.Err()) return //default: //continue } } }(ctx) //ifctx.Err()==nil{ //fmt.Println("Sleep10seconds...") //time.Sleep(time.Second*10) //} //ifctx.Err()!=nil{ //fmt.Println("Alredyexit...") //} time.Sleep(time.Second*3) cancelFunc() //for{ //ifctx.Err()!=nil{ //fmt.Println("gracefullyexit...") //break //} //} }
