代码如下: ```go package main import ( "fmt" ) type Task struct { f func(i interface{}) } func NewTask(h func(interface{})) (t *Task) { t = &Task{ f: h, } return } func (t *Task) Run() { fmt.Println("Runing...") } func test1(i *int) error { fmt.Println("test1", i) // do something here // ... return nil } func test2(s *string) (err error) { fmt.Println("test2", s) // do otherthing here // ... return } func main() { t1 := NewTask(test1) t2 := NewTask(test2) t1.Run() t2.Run() } ``` 报错: .\main.go:33:15: cannot use test1 (type func(*int) error) as type func(interface {}) in argument to NewTask .\main.go:34:15: cannot use test2 (type func(*string) error) as type func(interface {}) in argument to NewTask 请教诸位如何修改?谢谢
