如何从跨越多个页面的GET请求中提取所有结果？

Question

我已经成功地编写了调用API然后将结果转换为数据帧的代码

wax_wallet = "zqsfm.wam"

# Get Assets from AtomicHub API
response1 = requests.get(
    "https://wax.api.atomicassets.io/atomicassets/v1/assets?"
    f"owner={wax_wallet}"
    "&collection_whitelist=nftdraft2121"
    "&page=1"
    "&limit=1000"
    "&order=asc"
    "&sort=name")

# Save Response as JSON
json_assets = response1.json()

# Convert JSON to DataFrame
df = pd.json_normalize(json_assets['data'])

这个API每页最多返回1000个项目，因此我需要让它根据需要在尽可能多的页面中循环，并最终将结果存储到数据帧中

我试图用下面的代码解决它，但没有成功

asset_count = 2500
pages = int(math.ceil(asset_count / 1000))

# Get Assets from AtomicHub API
all_assets = []
for page in range(1, pages):
    url = f'https://wax.api.atomicassets.io/atomicassets/v1/assets?owner={wax_wallet}' \
          f'&collection_whitelist=nftdraft2121&page={page}&limit=1000&order=asc&sort=name'
    response = rq.get(url)
    all_assets.append(json.loads(response.text))["response"]

提前感谢您的帮助

我认为这会有帮助：

import requests

all_assets = []
URL = 'https://wax.api.atomicassets.io/atomicassets/v1/assets'
params = {
    'owner': 'zqsfm.wam',
    'collection_whitelist': 'nftdraft2121',
    'page': 1,
    'order': 'asc',
    'sort': 'name',
    'limit': 1000
}
with requests.Session() as session:
    while True:
        print(f"Getting page {params['page']}")
        response = session.get(URL, params=params)
        response.raise_for_status()
        _j = response.json()
        data = _j['data']
        if len(data) > 0:
            all_assets.append(data)
            params['page'] += 1
        else:
            break
print('Done')
