This article mainly introduces "how to achieve golang timing tasks time.Sleep and time.Tick". In daily operation, I believe many people have doubts about how to achieve golang timing tasks time.Sleep and time.Tick. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "golang timing tasks time.Sleep and time.Tick". Next, please follow the editor to study!

Generally speaking

Sleep uses sleep to complete the timing, and then continues to execute the cycle after the end to achieve the timing task.

The Tick function uses channel to block the current protocol and complete the execution of scheduled tasks.

Now let's take a look at the difference between the two methods.

Here we set the timing length to 5.

Using "Do Something" to simulate scheduled task execution time is divided into 1 s execution and 10 s execution

The code is as follows

Func Test_Sleep (t * testing.T) {for I: = 0; I

< 3; i++ { Debug("begin", time.Now().Format("2006-01-02_15:04:05")) Debug("Do something 1s") time.Sleep(time.Second * 1) Debug("end", time.Now().Format("2006-01-02_15:04:05")) time.Sleep(time.Second * 5) }}func Test_Tick(t *testing.T) { t1 := time.NewTicker(5 * time.Second)(5 * time.Second) for { select { case |Sleep---------->

| | Do- > | Sleep- > | |

16:22:20 on 2019-04-19 | DEBUG | Test_Trick () | 93 | end 2019-04-19 July 16 purl 22 purl 20

Set the task execution time to 1s

The interval between end and the next begin is 4s (fixed time interval-task execution time)

The process is roughly as follows:

(begin) Do- > (end)

| | DO- >-| Do- >-| |

| | Sleep- > | Sleep- > | |

Set the task execution time to 10s

The interval between end and the next begin is 5s (fixed time interval)

The process is roughly as follows:

| | DO- > | Sleep- > | Do- > | Sleep- > | |

Set the task execution time to 10s

The interval between end and the next begin is 0s

At this time, because the execution time of the task is longer than the fixed time interval, when the task is finished, there is no blocking, so you can execute the next time immediately.

The process is roughly as follows:

(begin) Do- > (end)

| | DO- > | Do--- > | |

| | Sleep- >-| Sleep- >-| |

At this point, the study on "how to implement golang timing tasks time.Sleep and time.Tick" is over. I hope to be able to solve your doubts.
