python - 如何为 json.load 设置正确的编码

Question

我一直在尝试以这种方式加载 json:

data = json.load(f)

由于某些原因，JSON 采用 windows1251 编码。因此尝试打开它会导致错误:

File "./labelme2voc.py", line 252, in main
    data = json.load(f)
  File "/home/dex/anaconda3/lib/python3.6/json/__init__.py", line 296, in load
    return loads(fp.read(),
  File "/home/dex/anaconda3/lib/python3.6/codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe1 in position 81: invalid continuation byte

我该如何解决这个问题？ JSON 加载没有这样的选项来指定编码

试试这个:

import json

filename = ...  # specify filename here

with open(filename, encoding='cp1252') as f:
    data = json.loads(f.read())
