Youtube Data API V3 返回 ssl.SSLWantWriteError: The operation did not complete (write) 错误

Question

我之前问过几乎相同的问题，但由于在尝试解决该问题时出现了一个新错误，这使最初的错误黯然失色，因此未能得到解决方案。问题是，当我尝试使用下面的代码上传 youtube 视频时，标题中出现错误（下面的完整跟踪）并且无法这样做。我对导致错误的原因一无所知，希望能提供任何帮助。

def upload(beatName, mainArtist, keywords, oneLiner):

    CLIENT_SECRET_FILE = 'client_secret.json'
    API_NAME = 'youtube'
    API_VERSION = 'v3'
    SCOPES = ['https://www.googleapis.com/auth/youtube']

    service = Create_Service(CLIENT_SECRET_FILE, API_NAME, API_VERSION, SCOPES)

    upload_date_time = DT.datetime(2020, 9, 3, 12, 30, 0).isoformat() + '.000Z'

    title = "OTOROSHI - "test"
    description = 'Test'

    request_body = {
        'snippet': {
            'categoryI': 10,
            'title': title,
            'description': description,
            'tags': keywords
        },
        'status': {
            'privacyStatus': 'private',
            'publishAt': upload_date_time,
            'selfDeclaredMadeForKids': False,
        },
        'notifySubscribers': True
    }

    mediaFile = MediaFileUpload('E:\Everything.mp4')

    response_upload = service.videos().insert(
        part = 'snippet,status',
        body = request_body,
        media_body = mediaFile
    ).execute()

概要

TLS/SSL 错误是由于以下任一级别可能发生的问题引起的：

1. 客户端应用程序的级别；
2. Google API 客户端库的级别及其相应的要求（请参阅下面列出的）；
3. 标准 Python 的 SSL 实现级别 (TLS/SSL wrapper for socket objects)；
4. 操作系统本身的级别。

针对上述OP的问题，我的建议如下：

在客户端应用程序级别处理 SSL 错误，如果遇到上述错误，不要一次性上传视频文件，请使用@ 987654322@.

对于 Python v2 和 v3，YouTube 数据 API 的可恢复上传功能的使用非常容易，如下所示。

请注意，使用此功能将使应用对网络相关错误更具弹性。

详情

在尝试使用下面引用的 Python 脚本之前，应确保下面列出的所有库（即 Python 包）都是最新的。 （只需在每个命名包上发出pip install --upgrade。）

• Google API Client Library for Python
  google-api-python-client
• Google Authentication Library for Python: oauthlib integration
  google-auth-oauthlib
• Google Authentication Library for Python: httplib2 transport
  google-auth-httplib2
• Google Authentication Library for Python
  google-auth

在修改您的应用之前，请测试 API 的可恢复上传功能（即Resumable Uploading Protocol）确实可以正常工作且不会出现错误（因此也不会出现 SSL 错误）。

首先要做的是下载久经考验的公共 Google 脚本upload_video.py。 （这个脚本也有一个official documentation。要从脚本中获得一个不言自明的使用信息页面，只需使用命令行选项--help发出它。）

如果您运行的是 Python v3，那么您必须修补 upload_video.py，如下所示。在任何情况下，为了测试可恢复上传功能，只需在命令行提示符下发出如下命令：

python upload_video.py --file your_video_file.mp4 --title '...' --description '...' --privacyStatus private

或者，根据情况：

python3 upload_video.py --file your_video_file.mp4 --title '...' --description '...' --privacyStatus private

请注意，您的客户端机密文件 -- client_secret.json -- 必须存在于托管 upload_video.py 的目录中。

在upload_video.py 成功运行后，请在您自己的 YouTube Studio 页面上检查新上传的视频（并最终将其删除）：

https://studio.youtube.com/channel/YOUR_CHANNEL_ID/videos/upload.

如果一切正常——没有 SSL 错误——那么您可以继续重构自己的代码，以便根据您的需要将 Python 代码包含在 upload_video.py 中。

修补upload_video.py

目前由 Google 提供，脚本 upload_video.py 使用 Python v2 语言编码；要使其与 Python v3 一起使用，请对其应用以下更改：

1. 此脚本的第一行：将 python 替换为 python3（这在 Windows 机器上不是必需的）；
2. 将import httplib 替换为import http.client；
3. 将所有出现的httplib. 替换为http.client.（请注意那里的点）；
4. 将所有print EXPRESSION 替换为print(EXPRESSION)；
5. 将所有except IDENTIFIER, e 替换为except IDENTIFIER as e。

或者，否则，请将以下.patch 文件应用于脚本文件：

上面的.patch文件很可能是由Python自己的工具2to3生成的。该工具还能够就地修改upload_video.py。 （安装它只需发出pip install 2to3。）
