Unless otherwise configured, the client libraries use Application Default Credentials to authenticate with Google Cloud Services. While this works for most applications, in some cases you may need to override this default. You can do so by providing the UnifiedCredentialsOption The following example shows how to explicitly load a service account key file:
[](std::string const& keyfile){ auto is = std::ifstream(keyfile); is.exceptions(std::ios::badbit);// Minimal error handling in examples auto contents = std::string(std::istreambuf_iterator<char>(is.rdbuf()),{}); auto options = google::cloud::Options{}.set<google::cloud::UnifiedCredentialsOption>( google::cloud::MakeServiceAccountCredentials(contents)); return google::cloud::advisorynotifications_v1:: AdvisoryNotificationsServiceClient( google::cloud::advisorynotifications_v1:: MakeAdvisoryNotificationsServiceConnection(options)); }
