漂亮的json如何运作？

Question

我是django-tastypie的新手。 当我尝试使用以下代码创建API时，

class PrettyJSONSerializer(Serializer):
    json_indent = 4

        def to_json(self, data, options=None):
            print '.................'
            options = options or {}
            data = self.to_simple(data, options)
            return simplejson.dumps(data, cls=json.DjangoJSONEncoder,
                                    sort_keys=True, ensure_ascii=False, indent=self.json_indent)


    class ShipmentResource(ModelResource):
        class Meta:
            queryset = Shipment.objects.all()
            serializer = PrettyJSONSerializer()

它给出了如下所示的输出，

{"shipments": [{"awb_bol": "AWB#6", "carrier": "Yellow", "etd_eta": "2013-04-14", "from_to": "KKD-HYD", "id": 1, "mode": "Transport", "pieces": "10.00", "po": "PO-123", "resource_uri": "/api/shipment/1/", "status": "W", "weight": "25.00", "wr": "WR-123"}, {"awb_bol": "BWAB", "carrier": "Green", "etd_eta": "2013-04-23", "from_to": "AMP-HYD", "id": 3, "mode": "Transport", "pieces": "1.30", "po": "OP-123", "resource_uri": "/api/shipment/3/", "status": "O", "weight": "1.40", "wr": "RW 45"}]}

但是我只需要上面输出这个甲壳虫，

{
    "shipments": [
        {
            "awb_bol": "AWB#6",
            "carrier": "Yellow",
            "etd_eta": "2013-04-14",
            "from_to": "KKD-HYD",
            "id": 1,
            "mode": "Transport",
            "pieces": "10.00",
            "po": "PO-123",
            "resource_uri": "/api/shipment/1/",
            "status": "W",
            "weight": "25.00",
            "wr": "WR-123"
        },
        {
            "awb_bol": "BWAB",
            "carrier": "Green",
            "etd_eta": "2013-04-23",
            "from_to": "AMP-HYD",
            "id": 3,
            "mode": "Transport",
            "pieces": "1.30",
            "po": "OP-123",
            "resource_uri": "/api/shipment/3/",
            "status": "O",
            "weight": "1.40",
            "wr": "RW 45"
        }
    ]
}

django-tastypie中是否提供任何默认功能。 请解决我的问题。 谢谢..

Answer 1

向simplejson.dumps添加分隔符= ['，'，'：']参数

return simplejson.dumps(data, cls=json.DjangoJSONEncoder, sort_keys=True, ensure_ascii=False, indent=self.json_indent, separators=[',',': '])                                   

这可以与标准的python json库一起很好地工作，但是由于它们的相似性，我认为它是相同的。

为了避免对页面的错误响应，我建议您将content_type ='application / json'添加到页面响应中。
