Question

我试图遍历json-web服务，将每个对象的属性写入数据库。下面是我的代码片段和输出json。我想将每个对象的值写入数据库，即每个项目的值。现在我的代码片段只打印最后一个对象的值，所以＆＃34; 1＆＃34;对于ItemCount。

"ListOfLa311ElectronicWaste": {
                        "La311ElectronicWaste": [
                            {
                                "CollectionLocation": "Gated Community/Multifamily Dw",
                                "DriverFirstName": "",
                                "DriverLastName": "",
                                "ElectronicWestType": "Microwaves",
                                "GatedCommunityMultifamilyDwelling": "Curb",

                                "CollectionLocation": "Gated Community/Multifamily Dw",
                                "DriverFirstName": "",

                                "ServiceDateRendered": "",

                                "IllegalDumpCollectionLoc": "",
                                "LastUpdatedBy": "",
                                "Name": "021720151654176722"
                            },
                            {

                                "DriverFirstName": "",

                                "IllegallyDumped": "N",
                                "ItemCount": "1",

                        ]
                    },

代码：

  f2 = open('C:\Users\Administrator\Desktop\DetailView.json', 'r')

        data2 = jsonpickle.encode( jsonpickle.decode(f2.read()) )

        url2 = "https://myla311.lacity.org/myla311router/mylasrbe/1/QuerySR"
        headers2 = {'Content-type': 'text/plain', 'Accept': '/'}

        r2 = requests.post(url2, data=data2, headers=headers2)

        decoded2 = json.loads(r2.text)

        for sr in decoded2['Response']['ListOfServiceRequest']['ServiceRequest']:
            SRAddress = sr['SRAddress']
            latitude = sr['Latitude']
            longitude = sr['Longitude']

            for ew in sr["ListOfLa311ElectronicWaste"][u"La311ElectronicWaste"]:
                CommodityType = ew['Type']
                ItemType = ew['ElectronicWestType']
                ItemCount = ew['ItemCount']

Answer 1

我试图发现为什么ItemCount正在为LAEwaste311中的最后一个JSON对象打印，其数量为1.

我的初始打印声明为print ItemCount

我能够用`print ew ['ItemCount']来解决这个问题，它按照上面的JSON中的说明返回了每个项目的3,6,1。

Python JSON循环只打印最后一个对象的值
