Python 如何使用凭据初始化Google云存储

我可以从文件中执行以下操作：

from google.cloud import storage
self.client = storage.Client.from_service_account_json('/Users/david/file-163219.json')

但是，如果我尝试直接传递凭据，则会出现错误：

credentials_dict = {
      "type": "service_account",
      "project_id": "asdf-163219",
      "private_key_id": "asdf2938492837498234",
}
credentials = service_account.Credentials.from_service_account_info(credentials_dict)
self.client = storage.Client(credentials=credentials)

但是我得到了一个错误：

credentials_dict = {
      "type": "service_account",
      "project_id": "asdf-163219",
      "private_key_id": "asdf2938492837498234",
}
credentials = service_account.Credentials.from_service_account_info(credentials_dict)
self.client = storage.Client(credentials=credentials)

google.auth.exceptions.DefaultCredentialsError:无法自动确定凭据。请设置GOOGLE_应用程序_凭据或显式创建凭据并重新运行应用程序。有关更多信息，请参阅

传递凭证dict的正确方法是什么？

由于来自\u服务\u帐户\u文件的方法

需要路径，因此可以使用临时文件。例如：

#!/usr/bin/env python
from google.cloud import storage
from google.oauth2 import service_account
import json
import os
import tempfile
if __name__ == '__main__':
    jsonfile = u"""<HERE GOES THE CONTENT OF YOUR KEY JSON FILE.
    CONSIDER THAT THERE ARE BACKSLASHES WITHIN THE PRIVATE KEY
    THEREFORE USE AN EXTRA BACKSLASH. FOR INSTANCE: 
    -----BEGIN PRIVATE KEY-----\\nSomeRandomText
    INSTEAD OF: 
    -----BEGIN PRIVATE KEY-----\nSomeRandomText"""
    fd, path = tempfile.mkstemp()
    try:
        with os.fdopen(fd, 'w') as tmp:
            tmp.write(jsonfile)
        credentials = service_account.Credentials.from_service_account_file(path)
        storage_client = storage.Client(credentials=credentials)
        bucket = storage_client.get_bucket("your-bucket")
        blobs = bucket.list_blobs()
        for blob in blobs:
            print(blob.name)
    finally:
        os.remove(path)

#/usr/bin/env python
从google.cloud导入存储
从google.oauth2导入服务_帐户
导入json
导入操作系统
导入临时文件
如果uuuu name uuuuuu='\uuuuuuu main\uuuuuuu'：
jsonfile=u”“”在显式设置客户端凭据时，它要求在创建存储客户端时传递客户端所代表的project。如果未传递，则返回到从环境推断的默认值

from google.cloud import storage
from google.oauth2 import service_account

credentials = service_account.Credentials.from_service_account_info(credentials_dict)
client = storage.Client(project='project_id', credentials=credentials)

你关注这个链接了吗？@KlausD.yes——它提供了两个选项（我都成功地做到了这一点），导出一个变量并从凭据文件路径加载它，但我想直接从python/json dict中执行。对，这是可以理解的。我的问题是如何不从文件而是从dict本身执行。检查此注释以获得另一个答案-看起来您可以为
