調用腳本 init.py：
import json
host_name_list = ["172.28.0.2"]
args = {"a":1}
...
cmd = "python /usr/local/bin/ansible_engine/src/ansible_utils.py -t playbook -i '%s' -u '%s' -p '%s' " \
      "-n '%s' -r '%s' -a '%s' -k '%s' -o '%s'" \
      % (json.dumps(host_name_list),host_user,host_passwd,playbook,result_file,json.dumps(args),private_file,json.dumps(port))
status,output = commands.getstatusoutput(cmd)
