我正在尝试使用 Google UrlShortener API 通过 OAuth2 和 API 密钥检索历史记录。我收到 200 OK 响应,但是当我尝试使用 pagetoken 或 pageToken 作为查询参数获取后续页面时,我总是得到相同的 nextPageToken 和相同的结果页面。奇怪的是,基于浏览器的 Google API 交互使用 start-token 而不是 pagetoken 或 pageToken 但是当我使用 start-token 时我没有得到 200 OK。
如何使用 UrlShortener API 进行分页?
这是我的代码:
import requests
import json
import time
import settings
from oauth2client.client import OAuth2WebServerFlow
from oauth2client.tools import run_flow
from oauth2client.file import Storage
def history():
"""Look up a user's history"""
flow = OAuth2WebServerFlow(client_id=settings.OAUTH2_CLIENT_ID,
client_secret=settings.CLIENT_SECRET,
scope='https://www.googleapis.com/auth/urlshortener',
redirect_uri='http://127.0.0.1:5000/callback')
storage = Storage('creds.data')
credentials = run_flow(flow, storage)
print("access_token: {}".format(credentials.access_token))
headers = {'Content-Type': 'application/json', 'Authorization': 'Bearer {}'.format(credentials.access_token)}
raw_url = 'https://www.googleapis.com/urlshortener/v1/url/history'
url = raw_url + '?key={}'.format(settings.API_KEY)
r = requests.get(url=url, headers=headers)
if r.ok:
output = "The history is {}.".format(r.json())
print(output)
if 'nextPageToken' in r.json().keys():
morePages = True
npt = r.json()['nextPageToken']
r_paged = None
while morePages:
time.sleep(2)
url = raw_url + '?pagetoken={}&key={}'.format(npt, settings.API_KEY)
r_paged = requests.get(url=url, headers=headers)
if r_paged.ok:
if 'nextPageToken' in r_paged.json().keys():
npt = r_paged.json()['nextPageToken']
morePages = True
else:
morePages = False
break
output = "The history is {}.".format(r_paged.json())
print(output)
else:
output = "Invalid request. Status code = {}, json = {}".format(r_paged.status_code, r_paged.json())
print(output)
else:
output = "Invalid request. Status code = {}, json = {}".format(r.status_code, r.json())
print(output)
