def master(request): data = {‘这是‘:‘主页‘} return JsonResponse(data, json_dumps_params={‘ensure_ascii‘:False}) |
显示效果：
首先我们看JsonResponse()的源码：

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) |
这里我们从根源开始找它编码错误的原因：
JsonResponse()在初始化的时候使用了json.dumps()把字典转换成了json格式，具体方法如下：

data = json.dumps(data, cls=encoder, **json_dumps_params) |

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) |
源码注释原文：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.
也就是说ensure_ascii是false的时候，可以返回非ASCII码的值，否则就会被JSON转义。
所以含有中文的字典转json字符串时，使用 json.dumps() 方法要把ensure_ascii参数改成false，即 json.dumps(dict，ensure_ascii=False)。
JsonResponse()接收参数有关键词参数，json_dumps_params=None ，用来给 json.dumps() 传参，所以 要在关键字参数后面拼个字典来传另一组关键字参数 ensure_ascii=False，即：
json_dumps_params={‘ensure_ascii‘:False}
解决方案：JsonResponse(data, json_dumps_params={'ensure_ascii':False})
