Python 过滤错误log并导出的实例

人气:0

前言:

测试过程中获取App相关log后,如何快速找出crash的部分,并导出到新的文件呢?

感兴趣的话,继续往下看吧~

思路:遍历多个日志文件,找出含有Error和Crash的日志,并把该行日志输出到另一个文件result.txt中。

def find_log(path):
  file_list = os.listdir(path)
  for file in file_list:
    file_name = file
    log_path = os.path.join(path, file)
    with open(log_path, 'rb') as f:
      lines = f.readlines()
      index = 0
      for line in lines:
        index += 1
        if 'Crash' in line.decode("utf8", "ignore") or 'Error' in line.decode("utf8", "ignore"):
          ss = re.findall(r'(.*Crash.*)', line.decode("utf8", "ignore"))
          zz = re.findall(r'(.*Error.*)', line.decode("utf8", "ignore"))
          if len(zz) > 0:
            with open('result.txt', 'a') as ff:
              ff.write('文件名:'+file_name + ' 第' + str(index) + '行: ' + zz[0] + '\n')
          elif len(ss) > 0:
            with open('result.txt', 'a') as ff:
              ff.write('文件名:'+file_name + ' 第' + str(index) + '行: ' + ss[0] + '\n')
          else:
            break

result.txt文件展示如下:
