总有一些程序在windows平台表现不稳定，动不动一段时间就无响应，但又不得不用，每次都是发现问题了手动重启，现在写个脚本定时检测进程是否正常，自动重启。
涉及知识点
代码分解
脚本主入口
if __name__ == '__main__':
#每5秒执行检查任务
schedule.every(5).seconds.do(check_job)
#此处固定写法，意思是每秒钟schedule看下是否有pending的任务，有就执行
while True:
schedule.run_pending()
time.sleep(1)
schedule的其它示例
import schedule
import time
def job(message='stuff'):
print("I'm working on:", message)
#每10分钟
schedule.every(10).minutes.do(job)
#每小时
schedule.every().hour.do(job, message='things')
#每天10点30分
schedule.every().day.at("10:30").do(job)
while True:
schedule.run_pending()
time.sleep(1)
检查无响应进程并重启
def check_job():
process_name = "xx.exe"
not_respond_list = list_not_response(process_name)
if len(not_respond_list) <= 0:
return
pid_params = " ".join(["/PID " + pid for pid in not_respond_list])
os.popen("taskkill /F " + pid_params)
if len(list_process(process_name)) <= 0:
start_program(r'E:\xx\xx.exe')
｝
查找符合条件的进程列表
def list_process(process_name, not_respond=False):
cmd = 'tasklist /FI "IMAGENAME eq %s"'
if not_respond:
cmd = cmd + ' /FI "STATUS eq Not Responding"'
output = os.popen(cmd % process_name)
return parse_output(output.read())
def list_not_response(process_name):
return list_process(process_name, True)
解析命令执行结果
def parse_output(output):
print(output)
pid_list = []
lines = output.strip().split("\n")
if len(lines) > 2:
for line in lines[2:]:
pid_list.append(line.split()[1])
return pid_list
tasklist示例输出

os.popen("taskkill /F " + pid_params)
if len(list_process(process_name)) <= 0:
start_program(r'E:\xxx\xx.exe')
if __name__ == '__main__':
schedule.every(5).seconds.do(check_job)
while True:
schedule.run_pending()
time.sleep(1)
