Go lang - Get current mouse cursor position with RobotGo
问题
我是一个Go语言的初学者，我想解决一个小任务：将鼠标光标的当前坐标打印到控制台，并在鼠标移动时更新坐标。为此，我使用了robotgo库，通过以下命令下载它："go get github.com/go-vgo/robotgo"，然后使用"go get -u github.com/go-vgo/robotgo"进行更新，并使用import "github.com/go-vgo/robotgo"导入它。以下是我编写的代码：
package main
import (
"fmt"
"github.com/go-vgo/robotgo"
)
func main() {
for {
x, y := robotgo.GetMousePos()
fmt.Printf("当前位置 X=%d, Y=%d", x, y)
if x == 540 && y == 960 {
fmt.Println("光标在中心位置")
}
robotgo.Move(x, y)
}
}
但是我遇到了错误：

更新 2023年3月16日 问题已通过完全删除库及其依赖项，然后重新安装解决。
英文:
I'm a beginner in Go and I want to solve a small task: to print the current coordinates of the mouse cursor to the console and update them if the mouse moves. For this, I took the library robotgo, downloaded it using "go get github.com/go-vgo/robotgo", then "go get -u github.com/go-vgo/robotgo", and imported it using import "github.com/go-vgo/robotgo". Here's the code I wrote:
package main
import (
"fmt"
"github.com/go-vgo/robotgo"
)
func main() {
for {
x, y := robotgo.GetMousePos()
fmt.Printf("Current position X=%d, Y=%d", x, y)
if x == 540 && y == 960 {
fmt.Println("Cursor @center")
}
robotgo.Move(x, y)
}
}
But I'm getting errors:

UPD 16.03.2023 problem was solved by completely removing the library and its dependencies, and then reinstalling it.

对于Windows系统，可以使用系统API：GetCursorPos
//go:build windows
package main
import (
"fmt"
"syscall"
"unsafe"
)
func main() {
userDll := syscall.NewLazyDLL("user32.dll")
getCursorPosProc := userDll.NewProc("GetCursorPos")
type POINT struct {
X, Y int32
}
var pt POINT
_, _, eno := syscall.Syscall(getCursorPosProc.Addr(), 1, uintptr(unsafe.Pointer(&pt)), 0, 0)
if eno != 0 {
fmt.Println(eno)
}
fmt.Printf("[cursor.Pos] X:%d Y:%d\n", pt.X, pt.Y)
}
请注意，这是一个使用Go语言编写的示例代码，用于获取鼠标光标的位置。它使用了Windows系统的user32.dll库中的GetCursorPos函数。
英文:
For windows, use the system API :GetCursorPos
//go:build windows
package main
import (
"fmt"
"syscall"
"unsafe"
)
func main() {
userDll := syscall.NewLazyDLL("user32.dll")
getWindowRectProc := userDll.NewProc("GetCursorPos")
type POINT struct {
X, Y int32
}
var pt POINT
_, _, eno := syscall.SyscallN(getWindowRectProc.Addr(), uintptr(unsafe.Pointer(&pt)))
if eno != 0 {
fmt.Println(eno)
}
fmt.Printf("[cursor.Pos] X:%d Y:%d\n", pt.X, pt.Y)
}
