| 1 2 3 | 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：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | 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：
| 1 | data = json.dumps(data, cls = encoder, * * json_dumps_params) |
接下来我们看看json.dumps()的源码：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 | 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}
