Python 3.x 使用Google API客户端defaut credentails创建Blogger API终结点时出错

我试图在谷歌云函数中创建一个BloggerAPI服务对象。我参考了（获取计算引擎、Kubernetes引擎、AppEngine灵活环境和云功能的凭据部分）中的示例

给出的示例是针对Google Starage的。我正在尝试将其转换为博客API的Google API客户端。我找不到有关如何使用此默认凭据创建Blogger API服务对象的文档。我试图重用来自的代码

我尝试了以下代码，但出现了错误。我知道这是错误的，但我没有关于如何使用此凭证的文档

from google.auth import compute_engine
import googleapiclient.discovery

credentials = compute_engine.Credentials()
print(type(credentials))

blogger = googleapiclient.discovery.build('blogger', 'v3', credentials=credentials)
print(blogger)

我得到以下错误：

到目前为止，我看到的问题是，您正在使用Google Compute Engine的客户端库（连接到GCP虚拟机），但您希望连接到Blogger

是一个如何使用正确的客户端库连接到Blogger的示例

管理凭据的方法是使用具有以下结构的credential.json文件：

{
  "web": {
    "client_id": "[[INSERT CLIENT ID HERE]]",
    "client_secret": "[[INSERT CLIENT SECRET HERE]]",
    "redirect_uris": [],
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token"
  }
}

在您的Python代码中，有以下内容：

import sys

from oauth2client import client
from googleapiclient import sample_tools


def main(argv):
  # Authenticate and construct service.
  service, flags = sample_tools.init(
      argv, 'blogger', 'v3', __doc__, __file__,
      scope='https://www.googleapis.com/auth/blogger')
  try:
      users = service.users()
      thisuser = users.get(userId='self').execute()

这个答案假设API调用是通过服务器或桌面进行的。我的问题是通过一个谷歌云函数来使用API，在这个函数中不能存储文件。给出的示例适用于Google存储API。我正试图为Blogger API做同样的事情。您的示例适用于云存储，因为云存储和云功能可以在GCP的同一个项目中。Blogger的不同之处在于，尽管它是Google的一部分，但它不是GCP的一部分，因此它不能成为项目的一部分。因此，通过本地主机或云功能对blogger的身份验证是相同的。要使用多个文件进行部署，您可以压缩所有文件，然后从压缩文件进行部署。
