GA管理API和Python错误，带有client_secrets.json文件

我最近提出了一个关于GA管理API的问题，我解释说示例脚本对我不起作用。因此，看看这个例子，我发现了一个完全不同的例子，它也不起作用，但我有一个不同的错误：

The client secrets were invalid: 
Missing property "client_secret" in a client type of "installed".
WARNING: Please configure OAuth 2.0

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

   client_secrets.json

with information from the APIs Console <https://code.google.com/apis/console>.

---

client_secrets.json是Oauth2身份验证，首先提示用户访问其帐户

P12文件是服务帐户身份验证。服务帐户就像虚拟用户一样，它们是预授权的，这意味着不会提示用户同意。要向Google Analytics预授权服务帐户，必须在Google Analytics网站的“管理”部分以帐户级别的用户身份添加服务帐户电子邮件地址。是的，服务帐户使用管理API

注意：Oauth2凭据和服务帐户凭据是在注册应用程序时在google开发者控制台上创建的。现在可以为服务帐户获取.json文件，而不仅仅是p12。但是，用于验证服务帐户和Oauth2的代码不同，这两个.json文件不能互换。（希望有道理）

"""Reference command-line example for Google Analytics Management API v3.
This application demonstrates how to use the python client library to access
all the pieces of data returned by the Google Analytics Management API v3.
The application manages autorization by saving an OAuth2.0 token in a local
file and reusing the token for subsequent requests. It then traverses the
Google Analytics Management hiearchy. It first retrieves and prints all the
authorized user's accounts, next it prints all the web properties for the
first account, then all the profiles for the first web property and finally
all the goals for the first profile. The sample then prints all the
user's advanced segments.
Before You Begin:
Update the client_secrets.json file
  You must update the clients_secrets.json file with a client id, client
  secret, and the redirect uri. You get these values by creating a new project
  in the Google APIs console and registering for OAuth2.0 for installed
  applications: https://code.google.com/apis/console
  Learn more about registering your analytics application here:
  https://developers.google.com/analytics/devguides/config/mgmt/v3/mgmtAuthorization
Sample Usage:
  $ python management_v3_reference.py
Also you can also get help on all the command-line flags the program
understands by running:
  $ python management_v3_reference.py --help
