简单的goroutine在Windows上不起作用

Question

I'm doing some tests with goroutines just to learn how they work, however it seems they are not running at all. I've done a very simple test:

package main

import (
    "fmt"
)

func test() {
    fmt.Println("test")
}

func main() {
    go test()
}

I would expect this to print "test" however it simply doesn't do anything, no message but no error either. I've also tried adding a for {} at the end of the program to give the goroutine time to print something but that didn't help.

Any idea what could be the issue?

Answer 1

program execution does not wait for the invoked function to complete

Go statements

Wait a while. For example,

package main

import (
    "fmt"
    "time"
)

func test() {
    fmt.Println("test")
}

func main() {
    go test()
    time.Sleep(10 * time.Second)
}

Output:

test
