python3.5中
无法反序列化bytes数据必须decode成str才可以
>>> import json >>> a = b‘{"username": "xxx"}‘ >>> c = json.loads(a) ‘‘‘ Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/json/__init__.py", line 312, in loads s.__class__.__name__)) TypeError: the JSON object must be str, not ‘bytes‘ ‘‘‘
3.5解决办法:
>>> a = b‘123‘ >>> c = json.loads(a) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/json/__init__.py", line 312, in loads s.__class__.__name__)) TypeError: the JSON object must be str, not ‘bytes‘ >>> c = json.loads(a.decode(‘utf-8‘)) >>> c 123
python3.6中
无论bytes类型或者str类型都可以反序列化
>>> import json >>> a = b‘{"username": "xxx"}‘ >>> c = json.loads(a) >>> g = b‘{"username": "xxx"}‘ >>> h = json.loads(g.decode("utf-8"))
