我正在尝试在 youtube 数据 api 中获取 nextPageToken 下面是我的代码，我想得到所有nextpageTokens。在循环中，我想重新分配nextPageToken

【解决方案1】：

假设您在最后一页时不会返回nextPageToken，那么您可以这样做：

# First request
r = requests.get("https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=50&channelId="+CHANNELID+"&order=date&key="+DEVELOPER_KEY)
json_data = r.json()                                                                                                
nextPageToken = json_data.get("nextPageToken")

# Retrieve all the rest of the pages
while nextPageToken:
    r = requests.get("https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=50&channelId="+CHANNELID+"&order=date&key="+DEVELOPER_KEY+"&pageToken="+nextPageToken)
    json_data = r.json()
    nextPageToken = json_data.get("nextPageToken")

当然，在循环内部，您可能还希望以某种适当的数据结构（列表、字典等）收集正在检索的数据。
