话不多说,直接上代码:
c4 = ser.read(ser.in_waiting).decode(encoding='gbk',errors='ignore')#errors="ignore") 忽略其中有异常的编码，仅显示有效的编码,errors="replace") 替换其中异常的编码，这个相对来可能一眼就知道那些字符编码出问题了。添加个这玩意即可解决,
当时试过,抛出异常啊,跳过啊,都有点问题, 一行代码搞定,
以下附我最近项目的一个用例,自行删减啊,我可不给你们删:
def Serial_com4_Ping_lj(self):
try:
# print('连接串口成功')
portx = STA_Serial
bps = 115200
timex = 5
ser = serial.Serial(portx, bps, timeout=timex)
# print("衔接串口成功:详情参数：", ser)
ser.write(chr(0x03).encode())
ser.write('\r'.encode("utf-8"))
ser.write('tail -f /var/log/iscm.log &\r'.encode("utf-8"))
ser.write('\r'.encode("utf-8"))
ser.write('tail -f /var/log/iscm_iot.log &\r'.encode("utf-8"))
ser.write('\r'.encode("utf-8"))
ser.write('tail -f /var/log/libqtrans.log &\r'.encode("utf-8"))
while True:

c4 = ser.read(ser.in_waiting).decode(encoding='gbk',errors='ignore')
if(c4=="exit"):#退出标志
break
else:
