處理不同格式的Python請求API

我會盡量直截了當，如何格式化這個輸出？

import requests
import pandas as pd
from bs4 import BeautifulSoup
import json

headers = {
    'access-control-allow-credentials': 'true',
    'access-control-allow-headers': 'Content-Type',
    'content-type': 'application/json; charset=utf-8',
    'referer': 'https://www.giga.com.vc/padaria?initialMap=c&initialQuery=padaria&map=category-1&page=2',
    'accept': '*/*',
    'accept-encoding': 'gzip, deflate, br',
    'x-request-id': '24af6e1c94114c5488296d68ef93daf2',
    'x-vtex-cache-status': 'EXPIRED',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.84 Safari/537.36'
}

req = requests.get(f'https://www.giga.com.vc/padaria?initialMap=c&initialQuery=padaria&map=category-1&page=1', headers=headers)
#     print(req)
soup = BeautifulSoup(req.content, 'lxml')

soup_script = soup.find_all('script')[14].text
print(soup_script)

收到的輸出：

{"Product:sp-139989":{"cacheId":"sp-139989","productId":"139989","description":"Bolinho sabor Duplo Chocolate Bauducco é irresistível. Sua Fórmula é enriquecida com vitaminas e cálcio, ótimo para ser levado na lancheira dos pequenos, na bolsa ou na mochila.

期望的輸出：productId、productName、description、ean、price、specificationGroups 以及我可以通過代碼輕松檢索到的東西。

謝謝。

可能的解決方案如下：

import requests
import pandas as pd
from bs4 import BeautifulSoup
import json
import re

# set to show all columns
pd.set_option('display.max_columns', None)

headers = {
    'access-control-allow-credentials': 'true',
    'access-control-allow-headers': 'Content-Type',
    'content-type': 'application/json; charset=utf-8',
    'referer': 'https://www.giga.com.vc/padaria?initialMap=c&initialQuery=padaria&map=category-1&page=2',
    'accept': '*/*',
    'accept-encoding': 'gzip, deflate, br',
    'x-request-id': '24af6e1c94114c5488296d68ef93daf2',
    'x-vtex-cache-status': 'EXPIRED',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.84 Safari/537.36'
}

req = requests.get(f'https://www.giga.com.vc/padaria?initialMap=c&initialQuery=padaria&map=category-1&page=1', headers=headers)
soup = BeautifulSoup(req.content, 'lxml')

soup_script = soup.find_all('script')[14].text
data = json.loads(soup_script)

# save raw data to file
with open("data.json", "w", encoding="utf-8") as file:
    file.write(json.dumps(data))

# filter out trash data and cleanup keys in dictionary
raw_target_data = [(re.sub(re_pattern_key_rename, r'\2', key), value) for key, value in data.items() if re.search(re_pattern_key_filter, key)]

# merge data to product_id nested dict
raw_product_id_data = {}
for key, value in raw_target_data:
    raw_product_id_data.setdefault(key, []).append(value)

# merge data to product_id dict
product_data = {}
for key, value in raw_product_id_data.items():
    product_data[key] = [{k: v for d in value for k, v in d.items()}]

# create dataframe for each product and add to list
all_dfs = []
for k, v in  product_data.items():
    df = pd.json_normalize(v)
    all_dfs.append(df)

# merge product dataframes into one
df = pd.concat(all_dfs).reset_index(drop=True)

df.head()
