python-3.x - 更改视频标题时出现 Youtube 数据 api 错误

问题描述

为什么我在下面给出的脚本上收到此错误：

Traceback (most recent call last):
  File "C:\Path\YoutubeApi\main.py", line 54, in <module>
    main()
  File "C:\Path\YoutubeApi\main.py", line 49, in main
    response = request.execute()

import os

def main():
    credentials = None
    # token.pickle stores the user's credentials from previously successful logins
    if os.path.exists('token.pickle'):
        print('Loading Credentials From File...')
        with open('token.pickle', 'rb') as token:
            credentials = pickle.load(token)

    if not credentials or not credentials.valid:
        if credentials and credentials.expired and credentials.refresh_token:
            print('Refreshing Access Token...')
            credentials.refresh(Request())
        else:
            print('Fetching New Tokens...')
            flow = InstalledAppFlow.from_client_secrets_file(
                'client_secrets.json',
                scopes=[
                    'https://www.googleapis.com/auth/youtube.force-ssl'
                ]
            )

            flow.run_local_server(port=8080, prompt='consent',
                                authorization_prompt_message='')
            credentials = flow.credentials

            # Save the credentials for the next run
            with open('token.pickle', 'wb') as f:
                print('Saving Credentials for Future Use...')
                pickle.dump(credentials, f)

    youtube = build('youtube','v3',credentials=credentials)

    request = youtube.videos().update(
        part = 'snippet',
        body={
            "id": "OSxK-tscmVA",
            "snippet":{
                "title":"It's changed",
            }
        }
    )
    

    response = request.execute()

    print(response)

if __name__ == '__main__':
    main()

脚本说明：

该脚本的作用是，如果没有名为 token.pickle 的文件，它将要求用户授权应用程序，并且脚本会将用户凭据存储在 token.pickle 文件中，这样用户就不必在每个单次运行，脚本的第 2 部分更改了我的 YouTube 视频的标题。

解决方案

不幸的是，您似乎不倾向于使用Videos.updateAPI 端点的官方规范：

您对端点的调用的请求正文也需要指定视频类别 ID才能被 API 后端接受。

请注意，update_video.py来自 Google 的示例代码（我在您的系列文章开头指出您作为有价值的信息来源）包含所有这些必需的东西。

再次，请承认您必须吸收（即理解）该代码。除了仔细阅读官方文档之外别无他法。
