大家对go语言陌生吗？大家有没有了解过关于go的协成呢，这里没有废话，直接上
使用go get 可以设置这个变量go env -w GOPROXY=https://goproxy.io,direct
会使go get 更加快

package test_2import ("fmt""testing"
)func workers(id int, taskCh chan int, resultCh chan int) {for task := range taskCh {fmt.Printf("worker %d start\n", id)resultCh <- task * 2}
}func getTaskData(a []int, taskCh chan int) {for i := 0; i < len(a); i++ {taskCh <- a[i]}close(taskCh)
}func TestExecuteAllTask(t *testing.T) {albums := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20}tasksCh := make(chan int, len(albums))resultCh := make(chan int, len(albums))for i := 0; i < 3; i++ {go workers(i, tasksCh, resultCh)}getTaskData(albums, tasksCh)for a := 0; a < len(albums); a++ {result := <-resultChfmt.Printf("结果为:%d \n", result)}
}
