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()
