【问题描述】:
我正在尝试运行 Python 代码以使用为 YouTube 生成的 API 密钥下载 YouTube 数据。我的问题是每当我尝试运行代码时,我都会收到警告和错误。该代码在我从 Coursera 下载时运行过一次,但现在在它停止运行后得到结果。
此代码的输出是一个 CSV 文件,其中包含视频数据,例如计数、观看计数、评论计数、不喜欢计数、收藏计数等。我稍后将使用这些数据对 R 或 Python 进行一些统计分析,作为我的一部分Coursera 上的课程。
PFB 我使用的代码:xxxxx 是我从 Google YouTube 数据 API v3 生成的 API 密钥
Enter code here

def youtube_search(options):
youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION, developerKey=DEVELOPER_KEY)
# Call the search.list method to retrieve results matching the specified
# Query term.
search_response = youtube.search().list(q=options.q, part="id,snippet", maxResults=options.max_results).execute()
videos = []

csvWriter.writerow(["title","videoId","viewCount","likeCount","dislikeCount","commentCount","favoriteCount"])
# Add each result to the appropriate list, and then display the lists of

for search_result in search_response.get("items", []):
if search_result["id"]["kind"] == "youtube#video":
#videos.append("%s (%s)" % (search_result["snippet"]["title"],search_result["id"]["videoId"]))
title = search_result["snippet"]["title"]
title = unidecode.unidecode(title) # Dongho 08/10/16
videoId = search_result["id"]["videoId"]
video_response = youtube.videos().list(id=videoId,part="statistics").execute()

args = parser.parse_args()
#try:
youtube_search(args)
#except HttpError, e:
# print ("An HTTP error %d occurred:\n%s" % (e.resp.status, e.content))
每当我运行代码时,都会出现以下错误:
-
viewCount = video_result[u'statistics']["viewCount"]
KeyError: '统计'
-
警告:googleapiclient.discovery_cache:file_cache 在使用 oauth2client >= 4.0.0 时不可用 回溯(最近一次通话最后): 自动检测中的文件“C:\Anaconda3\Anaconda3 4.2.0\lib\site-packages\googleapiclient\discovery_cache__init__.py”,第 36 行 从 google.appengine.api 导入内存缓存 ImportError:没有名为“google”的模块
在处理上述异常的过程中,又发生了一个异常:
Traceback(最近一次调用最后一次): 文件“C:\Anaconda3\Anaconda3 4.2.0\lib\site-packages\googleapiclient\discovery_cache\file_cache.py”,第 33 行,在 从 oauth2client.contrib.locked_file 导入 LockedFile ImportError:没有名为“oauth2client.contrib.locked_file”的模块
我该如何克服这个错误?
