UnicodeDecodeError:'utf8'编解码器无法解码位置0的字节0xa5:无效的起始字节 [英] UnicodeDecodeError: 'utf8' codec can't decode byte 0xa5 in position 0: invalid start byte

问题描述

我正在使用Python-2.6 CGI脚本，但是在执行json.dumps()时在服务器日志中发现了此错误，

I am using Python-2.6 CGI scripts but found this error in server log while doing json.dumps(),

Traceback (most recent call last):
  File "/etc/mongodb/server/cgi-bin/getstats.py", line 135, in <module>
    print json.dumps(​​__get​data())
  File "/usr/lib/python2.7/json/__init__.py", line 231, in dumps
    return _default_encoder.encode(obj)
  File "/usr/lib/python2.7/json/encoder.py", line 201, in encode
    chunks = self.iterencode(o, _one_shot=True)
  File "/usr/lib/python2.7/json/encoder.py", line 264, in iterencode
    return _iterencode(o, 0)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xa5 in position 0: invalid start byte

在这里，

​__get​data()函数返回dictionary {}.

在发布此问题之前，我已提及

Before posting this question I have referred this of question os SO.

下面的代码行伤害了JSON编码器，

Following line is hurting JSON encoder,

now = datetime.datetime.now()
now = datetime.datetime.strftime(now, '%Y-%m-%dT%H:%M:%S.%fZ')
print json.dumps({'current_time': now}) // this is the culprit

我得到了一个临时解决方案

I got a temporary fix for it

print json.dumps( {'old_time': now.encode('ISO-8859-1').strip() })

但是我不确定这样做是否正确.

But I am not sure is it correct way to do it.

推荐答案

该错误是因为字典中存在一些非ASCII字符，并且无法对其进行编码/解码.避免此错误的一种简单方法是使用encode()函数对此类字符串进行编码(如下所示)(如果a是具有非ascii字符的字符串):

The error is because there is some non-ascii character in the dictionary and it can't be encoded/decoded. One simple way to avoid this error is to encode such strings with encode() function as follows (if a is the string with non-ascii character):

a.encode('utf-8').strip()
