關(guān)于Python dict存中文字符dumps()的問(wèn)題
Background
之前數(shù)據(jù)庫(kù)只區(qū)分了Android,IOS兩個(gè)平臺(tái),游戲上線后現(xiàn)在PM想要區(qū)分國(guó)服,海外服,港臺(tái)服。這幾個(gè)字段從前端那里的接口獲得,code過(guò)程中發(fā)現(xiàn)無(wú)論如何把中文的value丟到dict中存到數(shù)據(jù)庫(kù)中就變成類似這樣**"\u56fd\u670d"**
Solution
1.首先懷疑數(shù)據(jù)庫(kù)編碼問(wèn)題,但看了一下數(shù)據(jù)庫(kù)其他字段有中文格式的,所以要先check數(shù)據(jù)庫(kù)(MySQL)的字符編碼。
可以看到明明就TMD是utf-8啊,所以一定不是數(shù)據(jù)庫(kù)層出現(xiàn)的問(wèn)題,回到代碼debug
2.Google一下
這個(gè)問(wèn)題好多都是Python2的解決方案,找到了一個(gè)感覺(jué)靠譜點(diǎn)的
dict1 = {'name':'張三'} print(json.dumps(dict1,encoding='utf-8',ensure_ascii=False))
博客中的解法,但是我的Python版本是3.9,就會(huì)報(bào)Error如下
Exception in thread Thread-1: Traceback (most recent call last): File "/usr/local/python3/lib/python3.9/threading.py", line 950, in _bootstrap_inner self.run() File "/usr/local/python3/lib/python3.9/threading.py", line 888, in run self._target(*self._args, **self._kwargs) File "/home/dapan_ext/project_table.py", line 91, in http_request self.get_data(project_response_data) File "/home/dapan_ext/project_table.py", line 115, in get_data json.dumps(dict_1, encoding='utf-8', ensure_ascii=False) File "/usr/local/python3/lib/python3.9/json/__init__.py", line 234, in dumps return cls( TypeError: __init__() got an unexpected keyword argument 'encoding'
意思就是:在__init__json這個(gè)東東的時(shí)候它不認(rèn)識(shí)'encoding'這個(gè)argument。
那就翻閱源碼康康->->:
def dumps(obj, *, skipkeys=False, ensure_ascii=True, check_circular=True, allow_nan=True, cls=None, indent=None, separators=None, default=None, sort_keys=False, **kw): """Serialize ``obj`` to a JSON formatted ``str``. If ``skipkeys`` is true then ``dict`` keys that are not basic types (``str``, ``int``, ``float``, ``bool``, ``None``) will be skipped instead of raising a ``TypeError``. If ``ensure_ascii`` is false, then the return value can contain non-ASCII characters if they appear in strings contained in ``obj``. Otherwise, all such characters are escaped in JSON strings. If ``check_circular`` is false, then the circular reference check for container types will be skipped and a circular reference will result in an ``OverflowError`` (or worse). If ``allow_nan`` is false, then it will be a ``ValueError`` to serialize out of range ``float`` values (``nan``, ``inf``, ``-inf``) in strict compliance of the JSON specification, instead of using the JavaScript equivalents (``NaN``, ``Infinity``, ``-Infinity``). If ``indent`` is a non-negative integer, then JSON array elements and object members will be pretty-printed with that indent level. An indent level of 0 will only insert newlines. ``None`` is the most compact representation. If specified, ``separators`` should be an ``(item_separator, key_separator)`` tuple. The default is ``(', ', ': ')`` if *indent* is ``None`` and ``(',', ': ')`` otherwise. To get the most compact JSON representation, you should specify ``(',', ':')`` to eliminate whitespace. ``default(obj)`` is a function that should return a serializable version of obj or raise TypeError. The default simply raises TypeError. If *sort_keys* is true (default: ``False``), then the output of dictionaries will be sorted by key. To use a custom ``JSONEncoder`` subclass (e.g. one that overrides the ``.default()`` method to serialize additional types), specify it with the ``cls`` kwarg; otherwise ``JSONEncoder`` is used. """ # cached encoder if (not skipkeys and ensure_ascii and check_circular and allow_nan and cls is None and indent is None and separators is None and default is None and not sort_keys and not kw): return _default_encoder.encode(obj) if cls is None: cls = JSONEncoder return cls( skipkeys=skipkeys, ensure_ascii=ensure_ascii, check_circular=check_circular, allow_nan=allow_nan, indent=indent, separators=separators, default=default, sort_keys=sort_keys, **kw).encode(obj)
注意到這里:
If ``ensure_ascii`` is false, then the return value can contain non-ASCII
characters if they appear in strings contained in ``obj``. Otherwise, all
such characters are escaped in JSON strings.
意思就是:
ensure_ascii置為false時(shí),返回值就可以返回非ASCII編碼的字符,這豈不正是我們需要的,Got it!
回去改代碼:
server_name = str(related['name']) # print(server_name) dict_1 = {'appKey': related['appKey'], 'client': related['client'], 'name': server_name} crasheye.append(dict_1) crasheyes = json.dumps(crasheye, ensure_ascii=False)
