先说的让人兴奋的吧,“GO的库开发在windwos上尽然是一摸一样的啊”
C:\go-pro\go-self-package>go build gin-main.go
2017/09/20 14:39 1,936,384 gin-main.exe
2017/09/20 14:35 89 gin-main.go
2 个文件 1,936,473 字节
2 个目录 261,820,047,360 可用字节
C:\go-pro\go-self-package>gin-main.exe
1 is ok
2 is ok
这就是我为什么坚持GO的原因,名厂名牌,就是不一样啊,比那个WebAssembly强啊!!!!
为什么这么说呢,因为,我们伟大的GO尽然可以调用win32系统函数啊!!!!!
哇,哈哈哈,这不是强一点儿,是上了天啊!!!!!!
windows前端的兄弟姐妹们,我们开GO吧
一 DEMO
//win.go 显示磁盘剩余空间,win32系统函数"Kernel32.dll"=>"GetDiskFreeSpaceExW"
import (
"syscall"
"unsafe"
"log"
)
func main() {
kernel32, _ := syscall.LoadLibrary("Kernel32.dll")
defer syscall.FreeLibrary(kernel32)
GetDiskFreeSpaceEx, _ := syscall.GetProcAddress(syscall.Handle(kernel32), "GetDiskFreeSpaceExW")
lpFreeBytesAvailable := int64(0)
lpTotalNumberOfBytes := int64(0)
lpTotalNumberOfFreeBytes := int64(0)
r, _, _ := syscall.Syscall6(uintptr(GetDiskFreeSpaceEx), 4,
uintptr(unsafe.Pointer(syscall.StringToUTF16Ptr("F:"))),
uintptr(unsafe.Pointer(&lpFreeBytesAvailable)),
uintptr(unsafe.Pointer(&lpTotalNumberOfBytes)),
uintptr(unsafe.Pointer(&lpTotalNumberOfFreeBytes)), 0, 0)
if 0!=r {
log.Printf("Free %dmb", lpTotalNumberOfFreeBytes/1024/1024)
}
}
//运行
go build win.go
C:\go-pro\go-win32>win.exe

看到没有,无与伦比啊,哈哈哈
Finally:
如此美妙,大家真的可以认真考虑一下,把GO跑到windows下了。
前途无量!!!!
