【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
//}
//}
}
