googleurl Shortener API总是返回带有pagetoken的相同页面

Question

我正试图使用googleurlshortener API检索OAuth2和API密钥的历史记录。我得到了一个200ok的响应，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。奇怪的是，基于浏览器的googleapi交互使用的是start token而不是pagetoken或pagetoken，但是当我使用start token时，我没有得到200的OK。在

如何使分页与urlshortenerAPI一起工作？在

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)

固定代码如下：

# New import:
import urllib.parse

# // snip
                time.sleep(2)
                f = {'start-token':npt, 'key': settings.API_KEY}
                formatted = '?' + urllib.parse.urlencode(f)
                url = raw_url + formatted
                r_paged = requests.get(url=url, headers=headers)
# // snip

基本上，忽略文档。不要使用pageToken，使用start token。此外，您需要使用适合python3的url解析器进行url编码。在
