def master(request): data = {'這是':'主頁'} return JsonResponse(data, json_dumps_params={'ensure_ascii':False})
顯示效果: 前端
首先咱們看JsonResponse()的源碼:python
class JsonResponse(HttpResponse): def __init__(self, data, encoder=DjangoJSONEncoder, safe=True, json_dumps_params=None, **kwargs): if safe and not isinstance(data, dict): raise TypeError( 'In order to allow non-dict objects to be serialized set the ' 'safe parameter to False.' ) if json_dumps_params is None: json_dumps_params = {} kwargs.setdefault('content_type', 'application/json') data = json.dumps(data, cls=encoder, **json_dumps_params) super(JsonResponse, self).__init__(content=data, **kwargs)
這裏咱們從根源開始找它編碼錯誤的緣由:json
JsonResponse()在初始化的時候使用了json.dumps()把字典轉換成了json格式,具體方法以下:app
data = json.dumps(data, cls=encoder, **json_dumps_params)
接下來咱們看看json.dumps()的源碼:編碼
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): 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)
源碼註釋原文: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.spa
也就是說ensure_ascii是false的時候,能夠返回非ASCII碼的值,不然就會被JSON轉義。
3d
因此含有中文的字典轉json字符串時,使用 json.dumps() 方法要把ensure_ascii參數改爲false,即 json.dumps(dict,ensure_ascii=False)。code
JsonResponse()接收參數有關鍵詞參數,json_dumps_params=None ,用來給 json.dumps() 傳參,因此 要在關鍵字參數後面拼個字典來傳另外一組關鍵字參數 ensure_ascii=False,即:blog
json_dumps_params={'ensure_ascii':False}ip
