使用 Python 通过 YouTube API V3 上传视频文件时卡在 0%（可恢复上传）

Question

我正在使用 YouTube API V3 在 YouTube 上上传可恢复的视频。执行代码时，响应的 status_code 为 200（但根据官方文档，如果 API 工作正常，则需要 201）。 当我打开 YouTube 频道时，那里的视频显示“0% 处理”。 此外，一段时间后，会出现一条消息“处理已放弃”（如所附屏幕截图所示）。 我试图在脚本中包含所需的参数，但没有任何方法可以改变 YouTube 频道上视频的处理级别。 这里的代码如下：

import requests
import json
import httplib2
import sys

class youtube:
    #Access token obtained from OAuth 2.0 Playground
    token = 'ya29.a0Af................................'

    def resumable_uploads(self):
    
        token = self.token
        url = 'https://www.googleapis.com/upload/youtube/v3/videos?uploadType=resumable&part=snippet,status,contentDetails'
        headers = {'Authorization': 'Bearer {}'.format(token), 'host': 'www.googleapis.com', 'content-type': 'application/json; charset=UTF-8', 'X-Upload-Content-Type': 'video/*'}
    
        body = {
                "snippet": {
                    "title": "Video 2 by Sidra ",
                    "description": "This is a description of my video",
                    "tags": ["cool", "video", "more keywords"],
                    "categoryId": 22
                },
                "status": {
                    "privacyStatus": "public",
                    "embeddable": True,
                    "license": "youtube",
                    "selfDeclaredMadeForKids" : True
                }
            }
        response = requests.request('POST', url, headers=headers, data=json.dumps(body))
        print("status_code: ", response.status_code)
    
        if response.status_code == 200: 
        
            location = response.headers['location']
            headers = {'Authorization': 'Bearer {}'.format(token),'content-type': 'video/*'}
        
            #converting file into Bytes
            video_file= open("testVideo.mp4", "rb")
            file_content = video_file.read()
            video_file.close()

            body = {
                "videoFile" : file_content
            }
        
            response = requests.request('PUT', location, headers=headers, data=body)
            print(response.text)
            print("status_code: ", response.status_code)

obj = youtube()
obj.resumable_uploads()

控制台的响应如下：

status_code:  200

我个人不建议您使用纯 HTTP 请求方法实现可恢复视频上传。要做到这一点非常棘手。

从fully working example 开始并修改它以满足您的需求更可行。

无论如何，这里是Resumable Upload Protocol 的官方（相当重的）文档。

只看一眼你的代码，我就注意到你错过了传递给第一个 HTTP 请求方法调用——POST——标头X-Upload-Content-Length。 （请注意，我没有完整地分析您的代码；请遵循我上面的建议。）
