Question

我正在尝试使用以下代码使用youtube的API插入视频。我已生成我的客户端密钥文件，但无法理解如何生成oauth2.json文件。

import httplib2
import os
import sys

from apiclient.discovery import build
from apiclient.errors import HttpError
from oauth2client.client import flow_from_clientsecrets
from oauth2client.file import Storage
from oauth2client.tools import argparser
from oauth2client import tools



# The CLIENT_SECRETS_FILE variable specifies the name of a file that contains
# the OAuth 2.0 information for this application, including its client_id and
# client_secret. You can acquire an OAuth 2.0 client ID and client secret from

CLIENT_SECRETS_FILE = "my_client_secret.json"

# This variable defines a message to display if the CLIENT_SECRETS_FILE is
# missing.
MISSING_CLIENT_SECRETS_MESSAGE = """
WARNING: Please configure OAuth 2.0

To make this sample run you will need to populate the client_secrets.json 
file
found at:

%s

with information from the Cloud Console
https://cloud.google.com/console

""" % os.path.abspath(os.path.join(os.path.dirname(__file__),
                       CLIENT_SECRETS_FILE))

# This OAuth 2.0 access scope allows for full read/write access to the
# authenticated user's account.
YOUTUBE_SCOPE = "https://www.googleapis.com/auth/youtube"
YOUTUBE_API_SERVICE_NAME = "youtube"
YOUTUBE_API_VERSION = "v3"


def get_authenticated_service():
    flow = flow_from_clientsecrets(CLIENT_SECRETS_FILE, scope=YOUTUBE_SCOPE,
    message=MISSING_CLIENT_SECRETS_MESSAGE)
    storage = Storage("%s-oauth2.json" % sys.argv[0])
    credentials = storage.get()

    if credentials is None or credentials.invalid:
        credentials = tools.run_flow(flow, storage)

    return build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION,
        http=credentials.authorize(httplib2.Http()))


def add_video_to_playlist(youtube,videoID,playlistID):
  add_video_request=youtube.playlistItem().insert(
  part="snippet",
  body={
        'snippet': {
        'playlistId': playlistID, 
      'resourceId': {
              'kind': 'youtube#video',
          'videoId': videoID
        }
    #'position': 0
    }
}).execute()




if __name__ == '__main__':
    youtube = get_authenticated_service()
    add_video_to_playlist(youtube,"yszl2oxi8IY","PL2JW1S4IMwYubm06iDKfDsmWVB-J8funQ")

如何生成OATUH2.JSON文件？

Answer 1

文件<yourscript>-oauth2.json用于存储凭据（访问令牌，刷新令牌，ID令牌，令牌到期日期等...）

来自google API client guide：

oauth2client.file.Storage类存储和检索单个凭据对象。该类支持锁定多个进程和线程可以在单个存储上运行。

如果文件不存在或其中的凭据无效，则运行身份验证流程：

if credentials is None or credentials.invalid:
    credentials = tools.run_flow(flow, storage)

因此，如果此文件已存在且包含有效凭据，则无需请求授权代码（通过用户注册和用户接受范围）来获取第一个访问令牌，因为它将使用现有访问令牌/刷新此文件中的令牌以访问Google API。
