[英]End API Pagination Loop in Python
I am trying to build a Python script where I retrieve all the invoices from Chargebee through their API. I am, however, coming up a bit short as I do not know how to properly end the loop once it has reached the last page.我正在尝试构建一个 Python 脚本,在其中我通过 API 从 Chargebee 检索所有发票。但是,我有点短,因为我不知道如何在循环到达最后一页后正确结束循环。 My current solution consists of inserting a break when the URL is the same as the last page.
我当前的解决方案包括在 URL 与最后一页相同时插入一个中断。 Unfortunately, this is not very sustainable as I have to update it every time the last next_offset value changes.
不幸的是,这不是很可持续,因为每次最后一个 next_offset 值更改时我都必须更新它。
My current code looks like this:我当前的代码如下所示:
import requests
import json
import pandas as pd
from requests.auth import HTTPBasicAuth
from pandas import json_normalize
invoices = []
customers = []
def GetInvoices():
url = 'https://company.chargebee.com/api/v2/invoices?limit=100&offset='
url1 = 'https://company.chargebee.com/api/v2/invoices?limit=100&offset='
while url:
print('----')
print('Requesting', url)
response = requests.get(url, auth=HTTPBasicAuth('APIKEY','pass'))
data = response.json()
invoices.extend(data['list'])
if url == 'https://company.chargebee.com/api/v2/invoices?limit=100&offset=["1507705200000","78206775"]':
df = json_normalize(invoices)
df.to_csv('InvoicesUS.csv')
print('----')
print('Invoice list has been exported!')
break
else:
url = url1 + data['next_offset']
I am very new to Python, so there might be a lot of unnecessary things in the script.我对 Python 很陌生,所以脚本中可能有很多不必要的东西。 It is working, but I would like to find a way to page through the API and close the loop once the last page has been appended.
它正在工作,但我想找到一种方法来翻阅 API 并在附加最后一页后关闭循环。
Thank you!谢谢!
Found a solution to the problem by using try/except.通过使用 try/except 找到了问题的解决方案。 The code now looks like this:
代码现在看起来像这样:
import requests
import json
import pandas as pd
from requests.auth import HTTPBasicAuth
from pandas import json_normalize
invoices = []
url = 'https://company.chargebee.com/api/v2/invoices?limit=100&offset='
url1 = 'https://company.chargebee.com/api/v2/invoices?limit=100&offset='
while url:
try:
print('----')
print('Requesting', url)
response = requests.get(url, auth=HTTPBasicAuth('APIKEY','pass'))
data = response.json()
invoices.extend(data['list'])
url = url1 + data['next_offset']
except KeyError:
df = json_normalize(invoicesUS)
print('----')
print('Invoice list has been exported!')
break
