oauth2client.client.ApplicationDefaultCredentialsError：＆＃39; type＆＃39;，＆＃39; authorized_user＆＃39;或者＆＃39; service_account＆＃39;应设置值

Question

我试图从我的Python脚本访问BigQuery API。目前，我正在尝试仅尝试让this sample运行。

我已创建凭据，设置环境变量并运行脚本，只是为了得到此错误：

oauth2client.client.ApplicationDefaultCredentialsError: An error was encountered while reading json file: /PATH/TO/MY/google_api_credentials.json (pointed to by GOOGLE_APPLICATION_CREDENTIALS environment variable): 'type' field should be defined (and have one of the 'authorized_user' or 'service_account' values)

嗯，它没有在JSON文件中设置：

{"installed":{"client_id":"blahblah.apps.googleusercontent.com","project_id":"blahblah","auth_uri":"https://accounts.google.com/o/oauth2/auth","token_uri":"https://accounts.google.com/o/oauth2/token","auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs","client_secret":"blahblah","redirect_uris":["urn:ietf:wg:oauth:2.0:oob","http://localhost"]}}

由于我从Google控制台下载了JSON，它应该可以正常工作吗？我不知道＆＃39;键入＆＃39;我需要定义。

Answer 1

您提供的JSON文件适用于OAuth客户端。使用应用程序默认凭据时，需要提供JSON服务帐户密钥。尝试转到this page，点击＆＃34;创建服务帐户＆＃34;，填写表单，然后选择＆＃34;提供新的私钥。＆＃34;
