在client_secret.json文件中，最后添加 redirect_uris 块. 您的文件应类似于: {"web":{"client_id":"foo"，"project_id":"bar"，"auth_uri":"foo"，"token_uri":"bar"，"auth_provider_x509_cert_url":"foo"，"client_secret": "bar"，"redirect_uris":" http://domain_name _where_you_want_to_redirect/"}}

In your client_secret.json file add redirect_uris block at the end. Your file should be like: {"web":{"client_id":"foo","project_id":"bar","auth_uri":"foo","token_uri":"bar","auth_provider_x509_cert_url":"foo","client_secret":"bar", "redirect_uris":"http://domain_name _where_you_want_to_redirect/"}}
