python读取日志

发布时间：2019-09-16 07:20:18编辑：auto阅读（2080）

场景：周一到周五早上6点半检查日志中的关键字，并发送相应的成功或者失败短信

用python27版本实现

日志内容如下：

[16-08-04 06:30:39] Init Outer: StkID:20205 Label:7110 Name:02ͨ Type:3 PriceDigit:4 VolUnit:0 FloatIssued:                                                               0 TotalIssued:                                                               0 LastClose:0 AdvStop:0 DecStop:0

[16-08-04 06:30:39] IB Recv DCT_STKSTATIC, Stock Total = 20207 Day=20160804, Ver=1470283608

配置文件如下：

[MobileNo]
user1 = num1
user2 = num2
user3 = num3

[code_IB]
keys = Stock Total

exepath = /home/level2/ib

failmsg = IB init fail!
day_of_week = 0-4
hour = 06
minute = 30
