使用 Python 访问 JSON 元素

如何解决使用 Python 访问 JSON 元素

我想访问“vin”、“make”、“year”等的个人数据并导出到 csv。我尝试通过

访问它

response = requests.request("POST",url,headers=headers,data=payload,timeout=15)

response_json = response.json()
#print(response_json)

for item in response_json['data']['hits']['hits']:
    
      active_year = item['year']
      active_make = item['make']
      active_model = item['model']
      active_trim = item['trim']
      active_vin = item['vin']
      active_mileage = item['mileage']
      active_basePrice = item['price']
                    
    
      print(str(active_year) + " " + active_vin + " " + active_make)

我收到一个 KeyError: 'year'

这是我正在使用的 JSON 树的一部分

`{
    "data": {
        "took": 31,"timed_out": false,"hits": {
            "total": 15786,"hits": [
                {
                    "_source": {
                        "vin": "JTHBW1GG0H2142332","stockNumber": "","bodyType": "Sedan","interiorPhotoUrl": "https://cdn.spincar.com/swipetospin-viewers/vroomadesaatlanta/jthbw1gg0h2142332/20201203212657.Z81AZWJL/closeups/cu-10.jpg","diesel": 0,"leadFlagPhotoUrl": "https://cdn.spincar.com/swipetospin-viewers/vroomadesaatlanta/jthbw1gg0h2142332/20201203212657.Z81AZWJL/closeups/cu-0.jpg","listingPrice": 26980,"color": "Black","year": 2017,`

我只是对语法有点困惑，因为我可以以同样的方式访问二维数组中的数据。

解决方法

您跳过了 json 的“_source”部分。这应该可以解决它。

response = requests.request("POST",url,headers=headers,data=payload,timeout=15)

response_json = response.json()
#print(response_json)

for item in response_json['data']['hits']['hits']:
      source = item['_source'] # THIS WAS MISSING
    
      active_year = source['year']
      active_make = source['make']
      active_model = source['model']
      active_trim = source['trim']
      active_vin = source['vin']
      active_mileage = source['mileage']
      active_basePrice = source['price']
                    
    
      print(str(active_year) + " " + active_vin + " " + active_make)
