处理 Oauth2.0 将视频添加到 YouTube 播放列表，不断添加视频的问题答案

【问题描述】：

我正在用 Python 编写代码来自动将视频添加到 YouTube 播放列表。该代码确实成功地将视频添加到播放列表，但是对于我添加的每个视频，都会提示我登录同意屏幕。对于我添加的每个视频，身份验证流程都会重复。我希望只做一次。

def insertPlaylistItem(playlistId, videoID):   
    api_service_name = "youtube"
    api_version = "v3"
    client_secrets_file = "client_secret.json"

    flow = google_auth_oauthlib.flow.InstalledAppFlow.from_client_secrets_file(client_secrets_file, scopes)
    credentials = flow.run_console() # Save these credentials
    youtube = googleapiclient.discovery.build(api_service_name, api_version, credentials=credentials)

    request = youtube.playlistItems().insert(
            part="snippet",
            body={
                "snippet": {
                    "playlistId": playlistId,
                    "position": 0,
                  "resourceId": {
                    "kind": "youtube#video",
                    "videoId": videoID
                }
                }
            }
        )
    response = request.execute()

    print(response)

client_secret.json 是这种形式：

{
    "installed":{
        "client_id":"XXXXXXXXXXXXXXXXXXXXXXXXXXX.apps.googleusercontent.com",
        "project_id":"XXXXXX",
        "auth_uri":"https://accounts.google.com/o/oauth2/auth",
        "token_uri":"https://oauth2.googleapis.com/token",
        "auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs",
        "client_secret":"XXXXXXXXXXXXXXXXXXXXXXX",
        "redirect_uris":[
            "urn:ietf:wg:oauth:2.0:oob",
            "http://localhost"
            ]
    }
}

有没有办法存储身份验证流程提供的这些凭据，以便以后使用？我已经通读了https://developers.google.com/youtube/v3/docs/playlists/insert，在那里我让它适用于javascript，但我只是不太明白Python的方式。我是不是对 Oauth2.0 流程理解有误？

使用 javascript，我能够以如下形式获得 token.json：

{
    "access_token":"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    "refresh_token":"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
    "scope":"https://www.googleapis.com/auth/youtube.force-ssl",
    "token_type":"Bearer",
    "expiry_date":1564674820338
}

【解决方案1】：

解决了！

我最终使用了 Python 的 oauth2client 模块。由于 oauth2.json 文件的存储方式不同，我还必须使用该模块的流程而不是 Google 的流程。使用 Google 的流程，我不断收到：KeyError: '_module'。

解决办法是：

import googleapiclient.discovery
import googleapiclient.errors
from oauth2client.client import flow_from_clientsecrets
from oauth2client.file import Storage
from oauth2client.tools import run_flow

def insertPlaylistItem(playlistId, videoID):
    api_service_name = "youtube"
    api_version = "v3"
    client_secrets_file = "client_secret.json"

    flow = flow_from_clientsecrets(client_secrets_file, scopes)
    storage = Storage("oauth2.json")
    credentials = storage.get()
    if credentials is None or credentials.invalid:
        credentials = run_flow(flow, storage)
        storage.put(credentials)

    youtube = googleapiclient.discovery.build(api_service_name, api_version, credentials=credentials)

    request = youtube.playlistItems().insert(
        part="snippet",
        body={
            "snippet": {
                "playlistId": playlistId,
                "position": 0,
                "resourceId": {
                    "kind": "youtube#video",
                    "videoId": videoID
                }
            }
        }
    )
    response = request.execute()
    print(response)
