Question

我正在尝试在youtube数据api中获取nextPageToken 下面是我的代码，我希望得到所有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")

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

    json_data = third_r.json()

    nextPageToken = json_data.get("nextPageToken")

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，在循环中，您可能还希望收集您在某些适当的数据结构（列表，字典等）中检索的数据。

我想在python youtube数据api中获取所有nextPageTokens
