Python调用Graylog APi 分析401错误登录日志

ret_lst处理完成后是一个list，内容如下：

[{'c_ip': '10.10.202.139', 'uname': 'ee'}, {'c_ip': '10.10.202.139', 'uname': 'tt'}, {'c_ip': '192.168.195.131', 'uname': 'ee'}, {'c_ip': '192.168.195.131', 'uname': 'aa'}, {'c_ip': '192.168.195.131', 'uname': 'bb'}, {'c_ip': '10.10.202.139', 'uname': 'liuyana'}, {'c_ip': '192.168.195.131', 'uname': 'bb'}, {'c_ip': '192.168.195.131', 'uname': 'eee'}, {'c_ip': '192.168.195.131', 'uname': 'bb'}, {'c_ip': '192.168.195.131', 'uname': 'cc'}, {'c_ip': '192.168.195.131', 'uname': 'ee'}, {'c_ip': '192.168.195.131', 'uname': 'ee'}, {'c_ip': '10.10.202.139', 'uname': 'tt'}, {'c_ip': '192.168.195.131', 'uname': 'aa'}, {'c_ip': '192.168.195.131', 'uname': 'eee'}, {'c_ip': '192.168.195.131', 'uname': 'aa'}, {'c_ip': '10.10.202.139', 'uname': 'lb'}, {'c_ip': '192.168.195.131', 'uname': 'ee'}, {'c_ip': '10.10.202.139', 'uname': 'lc'}, {'c_ip': '10.10.202.139', 'uname': 'la'}, {'c_ip': '10.10.202.139', 'uname': 'l'}, {'c_ip': '10.10.202.139', 'uname': 'la'}]
