Python 调用dll

Python 调用dll

为了方便python调用main.go种的Sum函数,需要先将main.go打包为dll文件,利用python调用dll文件

GO代码

main.go

package main

import "C"
import "fmt"

//export PrintBye
func PrintBye() {
    fmt.Println("From DLL: Bye!")
}

//export Sum
func Sum(a int, b int) int {
    return a + b;
}

func main() {
    // Need a main function to make CGO compile package as C shared library
}

将main.go打包为dll文件(需要gcc环境,下载地址)

go build -ldflags "-s -w" -buildmode=c-shared -o main.dll main.go

python调用main.dll

import ctypes
dll = ctypes.WinDLL(r'D:\Go_project\src\hello\a.dll')
print(dll.Sum(1,2))
