从YouTube api复制代码后，我不确定从何处继续

Question

我目前正在阅读本指南，以开始使用youtube api：https://developers.google.com/youtube/v3/quickstart/python在复制他们的示例代码的第2步中，该说明说要复制我的api密钥，并在示例代码中替换YOUR_API_KEY字符串。但是示例代码中没有YOUR_API_KEY

这里是他们提供的示例代码，我找不到api_key部分。我已经有了我的client_secret.json文件，但是当我替换client_secrets_file时，它仍然不会执行

# -*- coding: utf-8 -*-

# Sample Python code for youtube.search.list
# See instructions for running these code samples locally:
# https://developers.google.com/explorer-help/guides/code_samples#python

import os

import google_auth_oauthlib.flow
import googleapiclient.discovery
import googleapiclient.errors

scopes = ["https://www.googleapis.com/auth/youtube.force-ssl"]

def main():
    # Disable OAuthlib's HTTPS verification when running locally.
    # *DO NOT* leave this option enabled in production.
    os.environ["OAUTHLIB_INSECURE_TRANSPORT"] = "1"

    api_service_name = "youtube"
    api_version = "v3"
    client_secrets_file = "YOUR_CLIENT_SECRET_FILE.json"

    # Get credentials and create an API client
    flow = google_auth_oauthlib.flow.InstalledAppFlow.from_client_secrets_file(
        client_secrets_file, scopes)
    credentials = flow.run_console()
    youtube = googleapiclient.discovery.build(
        api_service_name, api_version, credentials=credentials)

    request = youtube.search().list(
        part="snippet",
        maxResults=25,
        q="surfing"
    )
    response = request.execute()

    print(response)

if __name__ == "__main__":
    main()

快速入门指南似乎不是最新的。它说应该有一个“ Credentials”下拉菜单，您应该选择“ API key”来获取使用API​​密钥的代码示例，但没有这种下拉菜单。

相反，在获得示例代码的地方，您需要取消选中“ Google OAuth 2.0”框。 （我还必须编辑和取消编辑“ part”字段，以刷新代码。）这将产生以下不同的示例代码，其具有预期的YOUR_API_KEY占位符：

# -*- coding: utf-8 -*-

# Sample Python code for youtube.channels.list
# See instructions for running these code samples locally:
# https://developers.google.com/explorer-help/guides/code_samples#python

import os

import googleapiclient.discovery

def main():
    # Disable OAuthlib's HTTPS verification when running locally.
    # *DO NOT* leave this option enabled in production.
    os.environ["OAUTHLIB_INSECURE_TRANSPORT"] = "1"

    api_service_name = "youtube"
    api_version = "v3"
    DEVELOPER_KEY = "YOUR_API_KEY"

    youtube = googleapiclient.discovery.build(
        api_service_name, api_version, developerKey = DEVELOPER_KEY)

    request = youtube.channels().list(
        part="snippet,contentDetails,statistics",
        id="UC_x5XG1OV2P6uZZ5FSM9Ttw"
    )
    response = request.execute()

    print(response)

if __name__ == "__main__":
    main()

然后您可以填写自己的API密钥。
