对于pDetails()中的项:
TypeError:“Popen”对象不可调用
看起来您希望收集子流程的标准输出。您必须使用pDetails.stdout
。以下是一个帮助您入门的示例:
import subprocess
p = subprocess.Popen("ls -la", shell=True, stdout=subprocess.PIPE)
output = b''.join(p.stdout).decode('utf-8')
print(output)
基于此,您的代码应该是这样的:
import subprocess, codecs
def serviceStatus(RadiaService):
cmd = 'sc query ' + RadiaService
pDetails = subprocess.Popen(cmd, shell = True, stdout = subprocess.PIPE)
return b''.join(pDetails.stdout).decode('utf-8')
def main():
print(serviceStatus('RCA'))
if __name__ == '__main__':
main()
注意:您不必收集列表中的输出,您可以直接将iterable馈送到join。如果您需要一个列表,您仍然不必使用for循环,您只需编写
status=list(pDetails.stdout)
尝试从pDetails()中的“for item in pDetails():”行中的pDetails()中删除括号,使其变为“for item in pDetails:”
