Python：JSONDecodeError：期望用双引号括起来的属性名称

Question

需要一些专家的帮助来解决这个问题并在缺失的地方强制使用双引号，这样我才能得到成功的响应。它在这里抛出错误 df = pd.io.json.json_normalize(rt.json(), record_path='offers')。 josn 看起来不错，我已经上演到 csv，所以不确定问题出在哪里

我的代码

import requests
import csv
import json
import pandas as pd
from pandas.io.json import json_normalize

url = "https://authentication.skiapi.com/access_token"

payload = {
    "client_id": "00c7fcf******",
    "client_secret": "7676cd5a********",
    "grant_type": "client_credentials"
}
headers = {"Content-Type": "application/json"}

response = requests.post(url, json=payload, headers=headers)
r = response.json() 
access_token = r.get('access_token') 
print(response.json()['access_token'])

   uri = "https://private-anon-73f9ac5d87-slinksmerchantapi.apiary-mock.com/v4/publisher/12633/offers?country=US"
headers = {'Authorization': access_token,'Content-Type': "application/json"}
rt = requests.get(uri, headers=headers)
      
df = pd.io.json.json_normalize(rt.json(), record_path='offers') ###problem is here 
#print(df)
df.to_csv(r"C:\\Users\ral\Downloads\\offers.csv", index=False)

我的 JSON 示例

    "has_more": true
    "offers": [{
        "coupon_code": null
        "terms": null

Answer 1

JSON 不正确 - 根据 cmets 缺少逗号加上 true 应该是 True 并且 null 应该是 None在python中

此外，您正在使用已弃用的接口 json_normalize

json.dumps(rt.json(), indent=2) 返回什么？有效的json？

已修补的 json

json = {
    "has_more": True,
    "offers": [{
        "coupon_code": None,
        "terms": None,
        "description": "40% Off Comforters & Other Cool Bedding Stuff Online at BoxLunch! Stock up on select blankets and bedding online only for a limited time -- See site for details. Valid 3/3-3/5",
        "offer_starts": "2017-03-03 08:00:00",
        "title": "40% Off Comforters & Other Cool Bedding Stuff Online at BoxLunch!",
        "url": "http://www.boxlunch.com/home/bedroom/?soffer=152034",
        "merchant_details": {
            "domain": "boxlunchgifts.com",
            "verticals": [],
            "country_code": None,
            "id": 393756,
            "metadata": {},
            "favourite": False,
            "partner_type": None,
            "merchant_id": 383288,
            "advertiser_id": 123456,
            "name": "BoxLunch",
            "countries": [],
            "domains": [
                "boxlunchgifts.com",
                "boxlunch.com"
            ]
        },
        "offer_type": "sale",
        "id": 152034,
        "offer_ends": "2017-03-05 08:00:00"
    }],
    "last_val": 152034,
    "next_val": 152032,
    "num_returned": 1
}
pd.json_normalize(json, record_path="offers")
