分页 SendinBlue Api 调用答案

【问题标题】：Pagination SendinBlue Api Call分页 SendinBlue Api 调用

【问题描述】：

我一直在尝试从 SendinBlue API 获取数据。问题是 API 每次调用限制为 100 个寄存器，并且我的 Python 循环无法正常工作。这是我目前所拥有的，通话效果很好。

import requests
import pandas as pd
from pandas import json_normalize
import json

results = []
pagination = 0

url = "https://api.sendinblue.com/v3/smtp/statistics/events"

querystring = {"limit":"100","offset":pagination,"days":"15"}

headers = {
    "Accept": "application/json",
    "api-key": "XXXXXXX"
}

#respuesta de la API
response = requests.request("GET", url, headers=headers, params=querystring) 
#convertir json a diccionario
data = json.loads(response.text)
#convertir diccionario a DataFrame
base = pd.json_normalize(data,record_path='events')

数据结构是这样的：

{'events': [
  {'email': 'chusperu@gmail.com',
   'date': '2020-10-18T17:18:58.000-05:00',
   'subject': 'Diego, ¡Gracias por registrarte! ????',
   'messageId': '<202010181429.12179607081@smtp-relay.mailin.fr>',
   'event': 'opened',
   'tag': '',
   'from': 'ventas01@grupodymperu.com',
  {'email': 'cynthiaapurimac@gmail.com',
   'date': '2020-10-18T17:52:56.000-05:00',
   'subject': 'Alvarado, ¡Gracias por registrarte! ????',
   'messageId': '<202010182252.53640747487@smtp-relay.mailin.fr>',
   'event': 'requests',
   'tag': '',
   'from': 'ventas01@grupodymperu.com'},
   ....

我尝试过的循环是这样的，但它只对前 200 个寄存器进行了分页。我做错了什么？

for i in data['events']:
    results.append(i)
while response.status_code == 200:
    pagination += 100
    querystring ['offset'] = pagination
    response = requests.request("GET", url, headers=headers, params=querystring)
    data = json.loads(response.text)

    for i in data['events']:
        results.append(i)
    else:
        break
print(results)

【问题讨论】：

for-else 循环将在循环之后触发else 部分，因此循环停止。
您介意详细说明一下代码吗？我不能让它工作

【解决方案1】：

终于明白了。

import requests
import pandas as pd
from pandas import json_normalize
import json

# Excel = "C:/Users/User/PycharmProjects/Primero/DataSendin.xlsx"

pagination = 0

url = "https://api.sendinblue.com/v3/smtp/statistics/events"

querystring = {"limit":"100","offset":f"{pagination}","days":"3"}

headers = {
    "Accept": "application/json",
    "api-key": "Your API key"
}

response = requests.request("GET", url, headers=headers, params=querystring) 

#respuesta de la API
try:   
    #convertir json a diccionario
    results = []
    data = json.loads(response.text)
    results.append(data)
    
    if not data:
        print("no hay data")
    
    else:
        while response.status_code == 200:
            pagination += 100
            querystring ['offset'] = pagination
            response = requests.request("GET", url, headers=headers, params=querystring)
            data = json.loads(response.text)
            results.append(data)            

            if not data:
                break          
            
except ValueError:
    "no data"

#convertir diccionario a DataFrame
final = list(filter(None, results))
base = pd.json_normalize(final,record_path='events')
base
