Question

我无法使用此脚本。我将DEVELOPER_KEY替换为我从Google API创建的API密钥。如果有人可以帮助我，我真的很感激。该脚本来自此页面：https://developers.google.com/youtube/v3/code_samples/python#search_by_keyword

#!/usr/bin/python

from apiclient.discovery import build
from apiclient.errors import HttpError
from oauth2client.tools import argparser


# Set DEVELOPER_KEY to the API key value from the APIs & auth > Registered apps
# tab of
#   https://cloud.google.com/console
# Please ensure that you have enabled the YouTube Data API for your project.
DEVELOPER_KEY = "REPLACE_ME"
YOUTUBE_API_SERVICE_NAME = "youtube"
YOUTUBE_API_VERSION = "v3"

youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION, developerKey=DEVELOPER_KEY)

我收到以下错误消息。

Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials.

Answer 1

这是google-api-python-client 1.6版的问题。使用以前的版本（1.5.5）可以解决问题。

Answer 2

如果您想使用google-api-python-client 1.6版，请执行以下操作。转到https://console.developers.google.com/apis/credentials。选择创建凭据，选择服务帐户密钥，选择App Engine默认服务帐户，下载JSON文件并将其放在项目文件夹中。然后将其设置为环境变量GOOGLE_APPLICATION_CREDENTIALS。

os.environ["GOOGLE_APPLICATION_CREDENTIALS"] = "./google_application_credentials.json"
