尝试在 python 中解析时出现 JSON 键错误

Question

我提出了一个 API 请求：

# set up the request parameters
params = {
  'api_key': 'XXXXXXXXXXXXXXXXXXXXXXXXX',
  'type': 'product',
  'item_id': 'XXXXXXXXX',
  'url': 'https://www.somestore.com',
  'output': 'json'
}

# make the http GET request to the API
api_result = requests.get('https://api.shopperapi.com/request', params)

product_data = json.loads(api_result.text)


if ((product_data["product.buybox_winner.seller.name"]=="MyStore.com") and (product_data["product.buybox_winner.availability.in_stock"]=="False")):
      my_Mailer("Its out of stock")

JSON 格式为：

{
  "request_info": {},
  "request_metadata": {},
  "request_parameters": {},
  "product": {
    "brand": "XXX",
    "title": "MyProductName",
    "upc": "XXXXXXXX",
    "item_id": "XXXXXXXXXX",
    "product_id": "XXXXXXXXXX",
    "item_number": "XXXXXXXXX",
    
    "model": "85888",
    "ratings_total": 45,
    "rating": 4.6,
    "type": "Housewares",
    "buybox_winner": {
      "price": 100.0,
      "was_price": 199.95,
      "currency_symbol": "$",
      "id": "XXXXXXXXXXXXXXXXXXXXXXXX",
      "": {
        "name": "MyStore.com",
        "id_secondary": "XXXXXXXXXXXXXXXXXXXXXXXXXX",
        "id": "XXXXXXXXXXXXXXXXXXXXXXXXXX"
      },
      "availability": {
        "raw": "OUT_OF_STOCK",
        "in_stock": false,
        "preorder": false
      }
}

我的错误是 KeyError: 'product.buybox_winner.seller.name'

我似乎无法解析这个 JSON 文件，因为我不知道如何正确引用密钥来检查它。

Answer 1

尝试以下方法：

product_data['product']['buybox_winner']['seller']['name']

您需要以这种方式使用键值访问 JSON。
