Pinterest API“书签”总是返回相同的字符串和数据

Question

我尝试按照 Pinterest API 文档中指示的方式使用分页，将“书签”作为参数传递给下一个 GET 请求，以便获取下一批数据。

但是，返回的数据与我收到的初始数据完全相同（没有传递“书签”），并且“书签”的值也相同！

由于存在此问题，我不断地一遍又一遍地接收相同的数据，并且无法获取完整的数据。就我而言，我试图列出所有活动。

这是我的Python代码：

url = f'https://api.pinterest.com/v5/ad_accounts/{ad_account_id}/campaigns'
payload = f"page_size=25"
headers = {
    "Accept": "text/plain",
    "Content-Type": "application/x-www-form-urlencoded",
    "Authorization": f"Bearer {access_token}"
}
response = requests.request("GET", url, data=payload, headers=headers)
print(response)
feed = response.json()
print(feed)
bookmark=''
if 'bookmark' in feed:
    bookmark = feed['bookmark']

print(bookmark)

while(bookmark != '' and bookmark != None and bookmark != 'null'):
    url = f'https://api.pinterest.com/v5/ad_accounts/{ad_account_id}/{level}s'
    payload = f"page_size=25&bookmark={bookmark}"
    headers = {
        "Accept": "text/plain",
        "Content-Type": "application/x-www-form-urlencoded",
        "Authorization": f"Bearer {access_token}"
    }
    response = requests.request("GET", url, data=payload, headers=headers)
    print(response)
    feed = response.json()
    print(feed)
    bookmark = feed['bookmark']
    print(bookmark)

我认为您在 while 中的条件是错误的，因此您最终会陷入相同的循环。我目前也在使用 Pinterest API，下面是我修改后的实现，如何获取广告帐户列表。

基本上，您正在测试书签是否为None。如果是，则可以返回结果，否则将书签附加到查询参数中并再次调用端点。

from app.api.http_client import HttpClient


class PinterestAccountsClient():

    def get_accounts(self, credentials) -> list[dict]:
        headers = {
            'Authorization': f"Bearer {credentials('access_token')}"
        }
        params = {
            'page_size': 25
        }

        accounts = []
        found_last_page = False
        while not found_last_page:
            try:
                response = HttpClient.get(self.listing_url, headers=headers, params=params)
                items = response.get('items', [])
                bookmark = response.get('bookmark')

                if bookmark is None:
                    found_last_page = True
                else:
                    params['bookmark'] = bookmark

                accounts.extend([{
                    'id': account['id'],
                    'name': account['name']
                } for account in items])

        return accounts
