我正在使用一個對請求結果進行分頁的 API，該 API 還方便地生成一些包含分頁信息的“超媒體”值；這些值之一是'next_page'。我正在嘗試創建一個接受請求的循環，記錄此“next_page”值，然后使用“next_page”的值運行另一個請求，并記錄下一頁，依此類推，直到“next_page”的值=“無”。到目前為止，這是我的功能，但這只是填充列表中的一項，而應該有 3 項。pages = []def build_requests(request): request = 'https://api.performancehorizon.com'+request job = requests.get(request, headers=headers, params=params) req = job.json() hypermedia_np = req['hypermedia']['pagination']['next_page'] if hypermedia_np != 'None': next_page = req['hypermedia']['pagination']['next_page'] pages.append(next_page) job = requests.get('https://api.performancehorizon.com'+next_page, headers=headers, params=params) req = job.json() else: print("Done!")如何更改我的代碼以循環此作業，直到“next_page”的值為“None”？

您可以使用以下修改后的代碼
pages = []
def build_requests(request):
request = 'https://api.performancehorizon.com' + request
job = requests.get(request, headers=headers, params=params)
req = job.json()
hypermedia_np = req['hypermedia']['pagination']['next_page']
while hypermedia_np is not None or hypermedia_np != 'None':
next_page = req['hypermedia']['pagination']['next_page']
if next_page is not None or next_page != 'None':
pages.append(next_page)
job = requests.get('https://api.performancehorizon.com' + next_page, headers=headers, params=params)
req = job.json()
hypermedia_np = req['hypermedia']['pagination']['next_page']
else:
hypermedia_np = None
print("Done!")
或者您可以使用此簡化版本，這也適用于您的情況
pages = []
def build_requests(request):
request = 'https://api.performancehorizon.com' + request
job = requests.get(request, headers=headers, params=params)
req = job.json()
hypermedia_np = req['hypermedia']['pagination']['next_page']
while hypermedia_np is not None or hypermedia_np != 'None':
pages.append(hypermedia_np)
job = requests.get('https://api.performancehorizon.com' + hypermedia_np, headers=headers, params=params)
req = job.json()
hypermedia_np = req['hypermedia']['pagination']['next_page']
print("Done!")
