- 筆記
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] Init Outer: StkID:20206 Label:9802 Name:982 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 filepath = /home/level2/ib/datacollect.log exepath = /home/level2/ib exefile = dcib.exe failmsg = IB init fail! day_of_week = 0-4 hour = 06 minute = 30
python如下：
