python打开文件查询字符串时报UnicodeDecodeError: 'gbk' codec can't decode byte 0xaa in position 19: illegal multibyte sequence错误

 

当这样打开时报错了

lines = open(path).readlines()
open(path).close()

for line in lines:
    idx1 = line.find('检测到的 SN 为：')
    idx1 += len('检测到的 SN 为：')
    idx2 = line.find('  或许与您申请的SN不符，请联系技术提供方',idx1)
    responsetimestr = line[idx1:idx2]
    rts = responsetimestr

UnicodeDecodeError: 'gbk' codec can't decode byte 0xaa in position 19: illegal multibyte sequence

 

改为以下即可

lines = open(path,mode='r',encoding='UTF-8').readlines()
