解析从node.js收到的JSON对象时，json.loads（）给出了UnicodeEncodeError

我试图从我的node.js服务器发送一些json对象到python脚本。但是，当尝试使用json.loads将json对象转换为字典时，对于许多输入，存在UnicodeEncodeErrors。我需要做什么才能正确解码js对象。

您在Windows上运行python，默认编码为cp1252。 json编码为utf-8，因此出错。

>>> with open('blob.json', encoding='cp1252') as f:
...     j = json.load(f)
... 
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "/usr/local/lib/python3.6/json/__init__.py", line 296, in load
    return loads(fp.read(),
  File "/usr/local/lib/python3.6/encodings/cp1252.py", line 23, in decode
    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x9d in position 2795: character maps to <undefined>

请改用utf-8：

>>> with open('blob.json', encoding='utf-8') as f:
...     j = json.load(f)
... 
>>> print(len(j))
