python - 我想在python youtube数据api中获取所有nextPageTokens

我正在尝试在YouTube数据API中获取nextPageToken下面是我的代码，我想获取所有nextpageToken。
在循环中，我想重新分配nextPageToken

def get_next_videos():
  while True:
    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")

    second_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 = second_r.json()
    nextPageToken = json_data.get("nextPageToken")

    third_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 = third_r.json()
    nextPageToken = json_data.get("nextPageToken")

    fourth_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 = third_r.json()
    nextPageToken = json_data.get("nextPageToken")

最佳答案

假设在最后一页时不返回nextPageToken，则可以执行以下操作:

# 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)收集要检索的数据。
