Question

我正在使用Python YouTube API从一些视频ID中检索信息。我有时碰到了

gdata.service.RequestError：{'status'： 403，'body'：'私人视频'， 'reason'：'禁止'}

但是，我希望我的程序忽略错误并继续。 PFB的一些代码片段：

@contextlib.contextmanager 
def exception_ignore_handler():
    try:
        yield
    except Exception:
        pass

''' Get Video details ''' 
def WriteStatEntryDetails(entry_video_id,data_file):             
    entry = yt_service.GetYouTubeVideoEntry(video_id = entry_video_id)

    with exception_ignore_handler():
        author = entry.author[0].name.text    
        data_file.write(author)
        data_file.write(",")

    with exception_ignore_handler():        
        time = entry.published.text
        data_file.write(time)
        data_file.write(",")

    with exception_ignore_handler():
        category = entry.media.category[0].label
        data_file.write(category)
        data_file.write(",") 

    with exception_ignore_handler():
        duration = entry.media.duration.seconds
        data_file.write(duration)
        data_file.write(",")


    with exception_ignore_handler():
        view_count = entry.statistics.view_count
        data_file.write(view_count.rstrip())
        data_file.write(",")

    with exception_ignore_handler():
        rating = entry.rating.average   
        data_file.write(rating.rstrip())
        data_file.write(",")

''' Get the comment feed of a video given a entry_video_id'''         
def WriteStatCommentFeed(entry_video_id, data_file):  
    url = comment_feed_url % entry_video_id
    comment_feed = yt_service.GetYouTubeVideoCommentFeed(uri=url)

    try :
        numComments = comment_feed.total_results.text
        data_file.write(numComments)
    except:
        pass       

''' Populate data statistics '''  
def populate_data_stats(positive_video_id_list):
    data_file = open(data_statistics_file, "w")

    for entry_video_id in positive_video_id_list :
        data_file.write(entry_video_id)
        data_file.write(",")
        WriteStatEntryDetails(entry_video_id, data_file)
        WriteStatCommentFeed(entry_video_id, data_file)
        data_file.write("\n")
    data_file.close()

Answer 1

例外情况如下：

entry = yt_service.GetYouTubeVideoEntry(video_id = entry_video_id)

和

comment_feed = yt_service.GetYouTubeVideoCommentFeed(uri=url)

我添加了exception_ignore_handler，程序现在通过忽略异常来运行。

使用YouTube API时忽略Python中的异常/错误
