python - 从 API 到 CSV 的数据框

Question

我在 python 并尝试将数据从 API 导出到 csv

import requests
import pandas as pd


url = "https://api.bexio.com/2.0/article"
#r = requests.get('https://api.bexio.com/2.0/article')
headers = {
'Accept': "application/json",
'Content-Type': "application/json",
'Authorization': "Bearer xxx}

这很好用。

  [{"id":34,"user_id":1,"article_type_id":1,"contact_id":null,"deliverer_code":"","deliverer_name":"","deliverer_description":"","intern_code":"TEXLINE-SOLD","intern_name":"TEXLINE Sold out","intern_description":"","purchase_price":"0.900000","sale_price":"2.450000","purchase_total":null,"sale_total":null,"currency_id":1,"tax_income_id":16,"tax_id":16,"tax_expense_id":22,"unit_id":1,"is_stock":true,"stock_id":null,"stock_place_id":null,"stock_nr":0,"stock_min_nr":0,"stock_reserved_nr":0,"stock_available_nr":0,"stock_picked_nr":0,"stock_disposed_nr":0,"stock_ordered_nr":0,"width":null,"height":null,"weight":null,"volume":null,"html_text":null,"remarks":"

这里的问题是，我想将此数据导出到 csv，然后在表格中很好地列出。我试过

from pandas.io.json import json_normalize
dic = response.json()
df = pandas.DataFrame(dic)
df.to_csv('detections.csv', index=False, sep="\t")

或者用 Pandas 作为 pd。但这行不通。

Answer 1

试试 read_json如果您将 JSON 作为字符串:

df = pd.read_json(json_string)

或者，或者，使用 .json() 将 API 响应转换为 python 列表并直接创建一个 DataFrame从该列表中:

r = requests.get('https://jsonplaceholder.typicode.com/posts')
df = pd.DataFrame(r.json())

如果响应不是列表( [{..}, .., {..}] )，而是单个对象( {..} ):

r = requests.get('https://jsonplaceholder.typicode.com/posts/1')
df = pd.DataFrame(r.json(), index=[0])
