如何捕获python中遇到的unicodedecode错误并打印出有问题的字符串

args=('utf8', '\xfeFEF', 0, 1, 'invalid start byte')
encoding='utf8'
end=1
message=''

“…无法解码第8位的字节XXXX:无效的开始字节”

这应该可以让您开始：

try:
    s = '\xFEFEF'
    u = s.decode('utf8')
except UnicodeDecodeError as e:
    for p in dir(e):
        if not p.startswith('_'):
            print '%s=%r' % (p, getattr(e, p))

args=('utf8', '\xfeFEF', 0, 1, 'invalid start byte')
encoding='utf8'
end=1
message=''
object='\xfeFEF'
reason='invalid start byte'
start=0

结果:

args=('utf8', '\xfeFEF', 0, 1, 'invalid start byte')
encoding='utf8'
end=1
message=''
object='\xfeFEF'
reason='invalid start byte'
start=0
