Background
之前数据库只区分了Android，IOS两个平台，游戏上线后现在PM想要区分国服，海外服，港台服。这几个字段从前端那里的接口获得，code过程中发现无论如何把中文的value丢到dict中存到数据库中就变成类似这样**"\u56fd\u670d"**
Solution
1.首先怀疑数据库编码问题，但看了一下数据库其他字段有中文格式的，所以要先check数据库（MySQL）的字符编码。
可以看到明明就TMD是utf-8啊，所以一定不是数据库层出现的问题，回到代码debug
2.Google一下
这个问题好多都是Python2的解决方案，找到了一个感觉靠谱点的
dict1 = {'name':'张三'}
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，就会报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这个东东的时候它不认识'encoding'这个argument。
那就翻阅源码康康->->：
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)
注意到这里：
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置为false时，返回值就可以返回非ASCII编码的字符，这岂不正是我们需要的，Got it！
回去改代码：
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)
完美解决问题(●ˇ∀ˇ●)
