十二. golang其他

1. 执行脚本

如下golang可以执行python脚本

package main

import (
	"fmt"
	"os/exec"
)

func main() {
	cmd := exec.Command("/usr/local/bin/python3.9", "/Users/haha/GolandProjects/awesomeProject5/test.py")
	// 命令的错误输出和标准输出都连接到同一个管道
	stdout, err := cmd.StdoutPipe()
	cmd.Stderr = cmd.Stdout

	if err != nil {
		return
	}
	err = cmd.Start()
	if err != nil {
		return
	}
	// 从管道中实时获取输出并打印到终端
	for {
		tmp := make([]byte, 1024)
		_, err := stdout.Read(tmp)
		fmt.Print(string(tmp))
		if err != nil {
			break
		}
	}
	if err = cmd.Wait(); err != nil {
		return
	}
}

python脚本如下：

#!usr/bin/python3
assert 3 == 4

执行结果：

Traceback (most recent call last):
  File "/Users/haha/GolandProjects/awesomeProject5/test.py", line 2, in <module>
    assert 3 == 4
AssertionError
err =  exit status 1
